The recent research progress in bio-oil refining is reviewed，including distillation，solvent extraction，chromatography，membrane separation and supercritical extraction. Distillation under ambient or reduced pressure can be used in bio-oil separation，while it suffers from a problem in the thermal sensitivity of bio-oil. On the other hand，molecular distillation is more suitable for the bio-oil refining. Some species can be extracted from bio-oil via solvent extraction，while the major disadvantage of which is the difficulty in the separation of solvent with the extract(s) as well as the low extraction selectivity. Exploring or exploiting peculiar extracting agents with specific functional groups，which can uniquely interact with the desired component in bio-oil，might be an interesting research topic in the future. Chromatography can effectively separate and purify bio-oil，but its low throughput makes it only suitable for high value-added compounds. Supercritical CO2 extraction is potentially a good way in refining bio-oil due to its nearby ambient operation temperature. In addition，supercritical CO2 extraction does not need a process of back-extraction. Fundamental research and integrated technique exploitation for bio-oil refining may be important research topics in the future.

Flat plate heat pipe is one of the available technology to deal with the high density electronic cooling problem.

The adsorption separation of CO2，CH4 and N2 was studied via volumetric measurements of β-zeolite samples with different SiO2/Al2O3 ratios at 273 and 303 K. Results showed that all the obtained adsorption isotherms are well correlated with the Langmuir-Freundlich model. For a certain sample，the adsorption capacity for CO2 is much higher than that for CH4 and N2. The adsorption capacity for CO2 increases with the decrease in SiO2/Al2O3 ratio under same temperature and pressure. The Henry law′s constant and adsorption equilibrium selectivity of CO2，CH4，and N2 on different β-zeolite samples were calculated via Virial equation，showing that the β-zeolite samples have higher equilibrium selectivity for CO2 over N2 and CH4. The selectivity of CO2 over N2 and CH4 increases with the decrease in SiO2/Al2O3 ratio. Therefore，the β-zeolite sample with a low SiO2/Al2O3 ratio is a good candidate for the separation of carbon dioxide from its mixture with methane and nitrogen. The isosteric adsorption heat for CO2，CH4 and N2 calculated by Clausius-Clapeyron equation is independent with the increase of adsorption loading，which indicates thatβ-zeolite is an energetically homogenous adsorbent.

Al-based slurry catalysts using pseudo-boehmite as aluminum source were prepared by complete liquid phase technology, and the catalyst precursors Cu(NO3)2 and Zn(NO3)2 were dissolved in different solvents. The as-prepared catalysts were characterized by means of X-ray diffraction, N2 adsorption, Xray photoelectron spectroscopy and H2 temperature-programmed reduction. Performance of the catalysts was evaluated in a slurry reactor for the synthesis of dimethyl ether (DME) from syngas. Results indicated that different solvent has significant influence on the catalyst structure and performance. Using glycol as solvent, the catalyst shows a stable phase structure and largest pore diameter and pore volume, meanwhile, the catalyst has more reducible copper and can be easily reduced. Therefore, the catalyst shows enhanced CO conversation while keeping the DME selectivity unchanged.
