There is plentiful biomass, a renewable resource，in the world. Not only the problem of energy shortage can be solved，but also the amount of emission of carbon dioxide can be decreased by the effective utilization of biomass energy. Thermochemical conversion of biomass includes gasification, pyrolysis and liquefaction. Liquefaction has got more and more attention in recent years because of its advantages over other methods.

Compared with the traditional method, an improved process was developed to synthesize 8–hydroxyquioline aluminum (AlQ3) by chemical deposition in nitrogen atmosphere. The acidity of solution and reaction time influenced the yield of AlQ3 strongly.

The absorption of H2S in acid solution of Fe2(SO4)3 was carried out in order to study the technology of removing H2S by bacterial cultures of Thiobacillus ferrooxidans. Single factor test was designed to test the profile of desulfurization efficiency under different conditions of liquid–to–gas ratio (L/V), initial concentration of Fe3+([Fe3+]) and pH. Simulation analysis showed that the gas–liquid mass transfer rates in this experiment was much smaller than chemical reaction rate and was the controlling step of the H2S absorption process. The experiment results proved that liquid–to–gas ratio was the dominant factor of gas–liquid mass transfer rates, but initial [Fe3+] concentration and pH showed little effect. The optimal operation conditions were as follows L/V=0.6min－1；[Fe3+]=10 g·L－1; pH=2.0. Under such conditions, the efficiency of removing H2S by bacterial cultures was around 90%.

This paper studies batch absorption with a two–section column for the treatment of tail gas containing hydrogen chloride (HCl). The operation not only makes the emission of hydrogen chloride meet the environment standard, but also can produce hydrochloric acid as a by–product. In the lower section of the column, dilute hydrochloric acid is recycled at a large flow rate as the absorbent. Fresh water at a smaller flow rate is used in the upper section. The temperature of the absorbent in the lower section should be below 40℃. In a laboratory test column, when the concentration of dilute hydrochloric acid in the lower section is 1%～15%, the rate of absorption for hydrogen chloride was over 99.5 %. In an industrial test column, the average rate of absorption for hydrogen chloride reached 97.6% and the concentration of by–product hydrochloric acid was 10%～15%.
