摘　　要：采用正交实验法和极差分析法，以苯酚作为生物质焦油模化物，SiC多孔泡沫陶瓷作为催化剂负载体，实验研究不同气化反应条件和不同催化剂制备条件对苯酚气化制氢的H2产率、气化效率和H2浓度的影响。结果表明：气化反应温度和催化剂煅烧时间是影响气化指标的关键因素。H2产率最优时对应的反应条件为气化反应温度800℃，水碳比（S／C）为6，催化剂负载量为6％；H2产率最优时对应的催化剂制备条件为煅烧时间1h，煅烧温度700℃，孔隙率为20ppi。The influences of different reaction conditions and preparation conditions of catalyst on Hz yield, gasification efficiency and H2 concentration are investigated with orthogonal experiment method and range analysis method in which phenol as a biomass tar model, and SiC porous foam ceramic as catalyst carrier. The results show that the gasification reaction temperature and the catalyst calcination time are the key elements to affect the gasification indexes. The optimal reaction conditions for the H2 yield are as follows, reaction temperature is 800 ℃, steam-carbon ratio （S/C） is 6, and catalyst loading is 6%. The optimal catalyst preparation conditions for the H2 yield are that the calcination time is lh, calcination temperature is 700 ℃, and porosity is 20 ppi.
