This paper reviewed the current research of heat transfer enhancement technologies on the two-phase closed thermosyphon. Heat transfer enhancement technologies were classified into highly efficient working fluid application，inner surface treatment，pipe inserted into the thermosyphon，and other methods. The heat transfer enhancement mechanism of these technologies was analyzed. The result indicates that most technologies stay in the experimental level and lack the theoretical research. And they have not obtained any widespread industrial application yet. Theoretical study，research of the effect of parameters on the heat transfer performance，how to reduce the production costs of industrial application will be the hot research topics of heat transfer enhancement technologies with thermosyphon in the future.

There are many types of adsorbents which are used for adsorption and separation of CO2/CH4 binary mixtures system. It is the various characteristics of adsorbents that affect separation result. As a starting point，four kinds of adsorbent properties affecting separation，which include porous structure，exchangeable cations，surface chemistry and moisture of adsorbent，are summarized in this article and the reason of all kinds of influences are explained. We come to several conclusions，including that mesoporous is conducive to the separation and amine grafting；the introduction of corresponding exchangeable cations can enhance the affinity between quadrupole and adsorbents，and improve the adsorption selectivity；surface hydroxyl is also an important factor affecting grafting amine；moisture can enhance the separation performance of adsorbent but also is conducive to grafting amine.

Droplets freezing process by spray freezing leads to their complex microstructures due to the formation of ice crystals within droplets. Numerical simulation was conducted to study the effect of droplet size，gas velocity and environmental temperature on the freezing process for a single droplet. Uniform temperature model was adopted in the simulation of droplet freezing process. The results show that the total solidification time for larger droplet is about 3 orders longer than that for the smaller one. Freezing rate is enhanced as gas velocity increases and environmental temperature decreases. Using variance analysis method，it is found that droplet size，gas velocity and environmental temperature have significant impacts on droplet total solidification time（p=0.0063>0.05）. During cooling process，the ratio of droplet mass loss due to convection decreases to lesser extent with the increases of droplet size and gas velocity，which is about 2%. Lower environmental temperature，which is an influential parameter，results in lower droplet mass loss ratio.

In order to overcome the difficulty of being easily trapped in local optimal solution during the global optimization process of heat exchanger network，the Monte-Carlo random sampling technique was applied to the random combination of cold fluid and hot fluid in the heat exchanger network. Through this way，the random changes of optimization sequence about multi-dimensional parameters were accomplished，the global optimal result of heat exchanger network could be sought out during jumping out from one local minimum solution to another. Through a case study，compared with previous results，the better result was obtained using this optimization method which is more suitable to industrial applications.

A control method of total reflux by introducing temperatures of top part，upper-middle part and middle part in batch distillation column without reflux drum was proposed. The ethanol—n-propanol system identified as a typical ideal system was used to conduct the experimental study of this operation. The optimized temperature control conditions were determined by experiments：when the temperature of the top part was stable and difference between the upper-middle part and the top part was 0.3 ℃，the total reflux operation would be switched to the total withdrawal operation，and if the temperature of the middle part rose by 1 ℃，the total withdrawal operation should be converted to the total reflux operation. From the results of experiments under the same operating conditions，the influence of different feed concentrations on the overhead product average purity is not significant，basically maintained at 0.99（mass fraction）. Finally，compared with dual temperature control method under the same feed concentration and operating conditions，this tri-temperature control method reduces operating time by 23.3 min，promotes separation efficiency by 23.95%，increases the purity of product by 1.06% and increases the product yield by 1.08%.

The model for applying an internal thermally coupled reactive distillation column（ITCRDC）to hydrolysis of methyl acetate was studied by using the simulation software，Aspen Plus. On the premise of ensuring the purity of products and minimum approach temperature，the effects of the various configurations of ITCRDC on the energy saving were explored. The results suggested that configuration had great influence on the performance of ITCRDC for the hydrolysis reaction of methyl acetate and the optimal one was obtained. And the characteristic of the optimal configuration is that the reaction section is in the rectifying tower and the stripping tower is thermally coupled with the rectifying tower.

Steady state simulation research was carried out for one industrial fluidized catalytic cracking（FCC）unit using the simulation platform developed by our group. The unit model was calibrated and validated by the industrial data collected from the unit. The effects of regenerator heat remover duty on the unit operation were then simulated and analyzed in this paper. The simulation results showed that，via the regulation of regenerator heat remover duty，the unit operator could change unit heat balance effectively and tune up the ratio of catalyst to oil before violating the operating range of process variables，thus more feedstocks could be converted to lighter products and the products distribution could then be adjusted effectively. However it could also decrease the temperature of dense bed in second stage regenerator and then deteriorate the operating performance of regenerator，thus its application is not conducive to improve the initial activity of regenerated catalyst.

Aqueous-phase reforming of biomass-derived polyols is one of the ongoing and promising technologies for hydrogen production. In this paper，the recent advance in hydrogen production by aqueous-phase reforming of biomass-derived polyols is reviewed. First，the thermodynamic and kinetic considerations that form the basis of the process are discussed. Then，the reaction pathways and the catalytic system as well as the optimization of technological conditions are introduced. In comparison with the process of steam reforming，the advantages and disadvantages of aqueous-phase reforming are proposed. On the one hand，the technology of aqueous-phase reforming possesses the features of lower energy consumption，less processing steps and relatively simple post-processing. On the other hand，there are more side reactions and the yield of H2 is lower. Finally，the review points out that the research directions are the development of more effective and stable catalysts，and the reduction of the cost for catalysts preparation and the optimization of the processing condition in the future.

During the lifetime of an internal engine，carbon deposit forms at various locations，such as combustion chamber，injection nozzle and inlet valve. Engine carbon deposit has serious influences on the engine efficiency，driveability and exhaust emissions. In order to clean up the carbon deposit，gasoline additives have become a necessary part of modern engine fuel. A large number of research literatures suggest that carbon deposit formation has two steps，i.e. initiation and growth；and these processes would be affected by metal surface temperature，fuel composition，injection rate，and many other factors. The use of a particular structure of the organic amines which can be adsorbed on metal surfaces and disperse pectin can clean the extensive carbon deposit. In addition，the composition，the development and the evaluation method of gasoline detergent have been summarized.

A series of Al2O3-ZrO2 composite oxides were prepared by impregnation-deposition method. Ni2P/Al2O3-ZrO2 catalysts were prepared by temperature-programmed reduction in a H2 flow. The supports and catalysts were characterized by X-ray diffraction（XRD），N2 adsorption-desorption and X-ray photoelectron spectroscopy（XPS）. The effect of composite oxides on the performance of Ni2P catalysts was studied by thiophene hydrodesulfurization and pyridine hydrodenitrogenation. The results showed that the introduction of small amounts of ZrO2 on the surface of Al2O3 would not only keep high surface area of γ-Al2O3 but also reduce the contact between P or Ni and the surface of Al2O3，and therefore，promote the formation of Ni2P. Ni2P/Al2O3-ZrO2 catalyst made from Al2O3-ZrO2 support with 20% ZrO2 exhibited the highest activity. And the activity of catalyst would decrease with higher calcination temperature of supports.

A SiO2/TiO2 composite photocatalyst was prepared by microemulsion method using inorganic polymerized silicate as the silicon source and titanium sulfate as the titanium source. The influence of preparation conditions on photocatalytic activity was investigated，and the photocatalyst was characterized by SEM，FTIR，XRD and BET. The results prove that a strong interaction exists between SiO2 and TiO2 particles，the formation of Ti—O—Si bond inhibits the TiO2 particle growth and also defers the transformation of TiO2 from anatast to rutile phase. The photocatalytic degradation of dyes，such as methyl orange，shows that the photocatalytic activity of SiO2/TiO2 is not improved along with higher propotion of TiO2. when the amount of substance ratio between Silicon and Titanium was 1∶1，and the photocatalyst was hydrothermal synthesized for 2.5 h at 160 ℃，the decoloration rate of methyl orange under UV light irradiation for 15 minutes over the SiO2/TiO2 photocatalyst could reach 85.5%，which has better photocatalytic activity and higher specific surface area than the TiO2 photocatalyst prepared under the same condition.

Nano-N-doped TiO2 photocatalyst was prepared by Sol-Gel method at room temperature，using tetrabutyl titanate as raw material and urea as N source. The N/TiO2 photocatalyst was characterized by X-ray diffraction（XRD），TEM，UV-Vis DRS. The results show that the N doped extended the spectral response range of nano-TiO2 particles to the visible light region. The better process parameters are that：n(n-butyl titanate) ∶n(urea) of 1∶3 and calcinate time of 3.5 h at 400 ℃，under which nano-N/TiO2 is anatase phase and its average particle diameter is 13 nm. When the photodegradation of methyl orange，the optimal pH is 4.0，degradation rate of methyl orange can reach 70.5% after 3 h。

The effects of MgO loading amount，reaction temperature，reaction time，and the ratio of methanol to EC on the catalytic performance have been studied. The results demonstrated that the MgO-loading amount played an important role on the dispersion of MgO species and the basic property of catalysts. The best catalytic performance was obtained over the 12% MgO/NaY catalyst under 70 °C with a ratio of methanol to EC of 8∶1，affording a remarkable DMC yield of 89%.

Photo-responsive drug delivery systems（Pr-DDS）stands out as a clean and noninvasive DDS. For Pr-DDS，the release of entrapped drugs can be accelerated at a specific location and time upon light-activation，which promotes maximum efficacy. The typical chromophores，incorporated into the photo-responsive drug release systems to render it susceptible to light trigger，include azobenzene（photoisomerization type），spiropyran（formation of zwitterionic species），coumarin（formation of the photo-cross-linking structure），and nitrobenzyl esters（conversion from hydrophobic to hydrophilic block）. In this paper，the progress in Pr-DDS development has been reviewed according to their different chromophores，and their application is also involved. Among these four Pr-DDS，Azo，as the representatives of the photoisomerization type，is the most widely studied one，which involves themicelles，vesicles，hydrogels，liposomes，etc. And nitrobenzyl ester，as the representatives of the conversion from hydrophobic to hydrophilic block type，has attracted wide attention for the two-photon response capability. In conclusion，although great progresses had been made on Pr-DDS，but there were still many problems，including how to improve the biocompatibility，and how to achieve feasible targeted light-controlled release in vivo.

The development of environmental friendly polyurethane foams is a focus in polyurethane industry. By introducing soy protein isolate（SPI）and flame retardant polyols into polyurethane（PU），environmental friendly flame retardant high resilience flexible polyurethane foams were prepared by free foaming. The effects of SPI content and addition manner on the physical，mechanical，biodegradability，and flame retardant properties of PU foams were investigated. The results show that，introducing SPI by adding not by substituting for polyols is an effective way to improve the performance of PU foam. By adding a small amount of SPI，the open cell ratio，elongation at break，resilience，comfort factor，density，and indentation force deflection value of PU foam are increased，while the tensile strength，limited oxygen index，and compression set value are slightly affected. SPI changes the structure of rigid segments，hence effectively enhances the biodegradability of PU foam.

Chitosan（CS）/polyvinyl alcohol（PVA）blend films with different compositions were prepared by solution casting technical using 2% acetic acid/water as a solvent. The structure，hydrogen-bonding，thermal behaviors and crystallization of CS/PVA blend films were systematically investigated by variable temperature FTIR，TGA，DTA，DSC and WXRD.

The effects of PVA，PIP and TMC concentration，temperature and time of heat treatment on the composite membrane were studied，and the surface structure and morphology were analyzed by scanning electron microscope（SEM）and atomic force microscopy（AFM）. The experiment results showed that increasing PVA content would lead to the increase in the flux of the nanofiltration membrane，make the nanofiltration membrane more hydrophilic，and cause the surface of the nanofiltration membrane smoother. The optimal preparing condition of the composite membrane was 3.0 g/L TMC，1.0 g/L PIP，0.54 g/L PVA，1 min reaction time，and 10 min heat treatment at 50 ℃.The separation performance of self-made nanofiltration membrane，treating the solutions of Na2SO4，MgSO4，NaCl or MgCl2，was similar to that of the commercial nanofiltration membranes，such as Dow NF-270 and Synder. Furthermore，the nanofiltration membrane also showed very good separation and anti-fouling performance in the advanced treatment of deinking wastewater.

The effect of the amount of triphenylphosphine on furfural yield was investigated in the range of 0.05%—0.5% of corncob’s weight. The result shows that furfural yield reached 86% with triphenylphosphine’s amount of 0.25% in corncobs. Furfural yield was improved 20—25 percent compared to the traditional process. Therefore，the addition of triphenylphosphine could improve furfural yield obviously，which would have a good prospect in furfural production.

The synthesis of 3-methyl salicylic acid in supercritical or subcritical carbon dioxide has important meaning for the green synthesis of 3-methyl salicylic acid and resourcization of carbon dioxide. After comparing the catalytic activity of anhydrous potash，anhydrous sodium carbonate and so on，anhydrous potash was chosen as the best catalyst to synthesize 3-methyl salicylic acid directly from o-cresol by one-pot method in supercritical or subcritical carbon dioxide.

The result showed that the conversion of o-cresol and the yield of 3-methyl salicylic acid both increased at first with the increase of time，and then the conversion became stable，but the yield decreased slightly in the end. The conversion and the yield increased rapidly at first and then increased slowly with the increase of catalyst′s relatively dosage. The conversion and the yield increased rapidly at first but then decreased with the increase of reaction pressure or reaction temperature. The conversion is about 19.7% and the yield is about 17.5% under the optimal condition that reaction time was 3 hours，catalyst′s relatively dosage was 0.5，reaction temperature was 190 ℃ and reaction pressure was 8 MPa. In addition，a possible reaction mechanism was proposed.

In this paper，cracking C9 gasoline from Dushanzi Petrochemical Company is used as raw material and industrial equipment condition was simulated. The results of stability and 1000h activity of LY-C9-A1+LY-C9-A2 and contrast catalyst show that diene value of LY-C9-A1+LY-C9-A2 hydrogenation products is much lower than that of contrast catalyst even under the condition that inlet temperature of LY-C9-A1+LY-C9-A2 is 5～10 ℃ lower than that of contrast catalyst. The results indicated that LY-C9-A1+LY-C9-A2 possessed better hydrogenation activity comparing with contrast catalyst. Meanwhile，the heating rate of LY-C9-A1+LY-C9-A2 is slower than that of contrast catalyst，which shows that carbon deposition rate of LY-C9-A1+LY-C9-A2 is slower and hydrogenation stability is better. In conclusion，comprehensive properties of LY-C9-A1+LY-C9-A2 are superior to contrast catalyst and enjoy predictable industrial application prospect.

With α-MS，hydrogen as raw material，cumene was synthesized by catalytic hydrogenation in a trickle-bed. The work mainly investigated the influence of reaction temperature，pressure，circulation，feeding α-MS concentration，hydrogen oil ratio on hydrogenation reaction. The results showed that the reaction temperature can accelerate the reaction rate within the range of 60—120 ℃；hydrogenation reaction rate is the fastest with the pressure from 0.7 to 0.8MPa，processing capability is the largest；the improvement on hydrogen to oil ratio ensure raw materials and catalyst contact time under the premise of the reaction；the circulation rate and the concentration of the feed α-MS reaction rate can be changed but the actual processing capacity cannot be changed；the stability of catalytic activity is the premise of the hydrogenation. The constrains for bed design processing capacity is the key for the reduction of current hydrogenation effect and the limitation of production capacity.
