Experimental Research on Catalyzed Hydrothermal Gasification of Cellulose
摘要
Abstract
This paper uses a kind of Ni/C catalyst to study hydrothermal gasification of cellulose of main components of bio-mass so as to provide research basis for utilization of biomass hydrothermal conversion. It adopts the experimental method to respectively discuss effects of different temperatures,pressures and liquid-solid quality ratios on hydrothermal conversion of the cellulose,meanwhile it uses the autoclave reactor and the flow reactor to make experiment on catalyzed hydrothermal gasification characteristic and compare gasification characteristics under different operating conditions. It represents gasifi-cation characteristics by yields of components of gas products and carbon conversion efficiencies. Corresponding results indi-cate improvement of temperature and pressure can promote catalyzed hydrothermal gasification of the intermittent cellulose, and the gas yield and carbon conversion efficiency at 350 ℃ and under 4 MPa will reach to the highest. In addition,propor-tions of CH4 and H2 in gas products are higher. In the meantime,improvement of temperature can promote continuous cata-lyzed hydrothermal gasification and the gas product and carbon conversion efficiency of the continuous reaction under the high temperature are both superior to that of the intermittent reaction.关键词
