Abstract：The research studied the theory and technology of energy-saving， CO2 application and emission-reduction during biomass high-efficient utilization. In accordance with the requirements of the mission statement， bio-oil was selective hydrogenated under low temperature （<125 ℃） with high-efficient and stable catalyst （Ru/C） to generate easily separated gaseous olefins and aromatic hydrocarbons in liquid form. Biomass low-temperature gasification was also carried out to generate syngas. Besides， the complex fluid dynamics of fluidized bed， especially dense fluidized bed， was further understood. A series of technical problems for applying of microwave heating-IR thermal imaging technology for particle tracing was conquered. Benzene was used as model compound for experimental study of biomass tar catalytic gasification. The research in this year found a suitable catalysis for low-temperature biomass gasification to syngas， the effects of temperature and pressure on the product distribution was also revealed. Based on these， “microwave heating-infrared thermography” particles tracing method was developed to solve the three-dimensional particle motion information problem which is difficult to obtain by conventional testing methods. This new method has successfully applied to spouted fluidized bed， revealing the particle circulating mode， cycle distribution and residence time distribution of the heavy particles. Whats more， during the study of gasification tar removal by catalytic decomposition process， the influence of temperature， water vapor， bed height and bed material on the process was also analyzed. Significant research results are as follows： bio-oil catalytic conversion to chemicals will jointly published an article on SCIENCE in the near future. The achievement of flow reactor coupled with the reaction has received the second award for 2010 National Science and Technology Progress， 12 papers were also published， with an invention patent. CO2 high-efficient absorption with the biomass production published 1 SCI papers and applied 2 invention patents. Biomass by-product catalytic carbonization to produce high performance electromagnetic shielding materials published 1 SCI， 1 EI and 1 core journal papers， and obtained 2 invention patents， 2 new utility patents， and applied 1 invention patent. The use of separated CO2 to synthesis carbonate materials has published 2 SCI papers， and applied 1 invention patent.
