以纤维素为模型化合物，在连续进料流化床反应器中，采用一种优良的催化剂（Rh/CeO 2/SiO2），开发了一种新型的低温生物质制氢和合成气催化工艺。该催化剂同时促进了纤维素热解产物如焦油、焦炭等的重整和燃烧反应以及水煤气变换反应。在空气和水蒸汽的混合物存在下，纤维素在773 K下完全转化为气体产物。这项工作可以代表一种新的和节能的方法来合成氢气和合成气从生物质。(C)2002 Elsevier Science（美国）。
We have developed a novel catalytic process for hydrogen and syngas production from biomass at very low temperature using an excellent catalyst (Rh/CeO2/SiO2) in a continuous-feeding fluidized-bed reactor using cellulose as a model compound. The catalyst simultaneously promoted the reforming and combustion reactions of pyrolyzed products of cellulose, such as tar, char, and so forth, and the water-gas shift reaction. In the presence of a mixture of air and steam, the cellulose completely converted to gas products at 773 K. This work can represent a new and energy efficient approach to the synthesis of hydrogen and syngas from biomass. (C) 2002 Elsevier Science (USA).
