摘　　要：纤维素的催化氢解制备低碳多元醇是一种行之有效的生物质利用途径,其核心是催化剂的研究。以SBA-15为模板,引入生物碳源(大豆油),通过固液研磨法制备自还原型金属双功能催化剂x%Ni-y%W/SBA-15,并将其应用于纤维素氢解制备低碳多元醇。当镍、钨含量分别为10%和20%时,低碳多元醇的总收率最高,为51.37%。改变加氢组分,与20%W/SBA-15制成混合型双功能催化剂M+20%W/SBA-15(M=Pd/C,Raney Ni,Rh/C,Pt/C,Ir/C)催化纤维素氢解时,加入Pt/C和Ru/C的混合型催化剂催化效果最好,低碳多元醇的总收率分别为68.39%和53.43%。最后,对用固液研磨法制备自还原型金属双功能催化剂进行优缺点分析,在此基础上,对今后此法制备的催化剂在纤维素氢解中的应用进行了展望。The catalytic hydrogenation of cellulose into low carbon polyols with cellulose as raw material under certain conditions is an effective solution of biomass utilization,and its core is the research of the catalyst. SBA-15 as the template,through the solid liquid grinding with the introduction of biological carbon source（ soybean oil）,the self-reduced metal bifunctional catalysts x% Ni-y% W / SBA-15 was prepared,and it was applied to hydrogenation of cellulose into low carbon polyols. When the content of nickel and tungsten was respectively 10% and 20%,low carbon polyols had the highest total yield 51. 37%. The hybride bifunctional catalyst M ＋ 20% W / SBA-15（ M = Pd / C,Raney Ni,Rh / C and Pt / C,Ir / C） was prepared by changing the hydrogenation component mixed with 20% W / SBA-15. When this catalyst was applied to reaction mentioned above,it was found that the catalytic activity of Pt / C and Ru / C was best,the total yield of low carbon polyols was 68. 39% and 53. 43% respectively. Finally,the advantages and disadvantages of this catalyst preparation method were analyzed. On this basis,the future of the catalysts prepared by this method were applied to cellulose to chemicals was discussed.
