金属镍因其在生物质水蒸气气化和降低焦油方面的活性而被选为生物质气化的催化剂。考察了铂、钴、铁等助剂对生物质气化的影响。感兴趣的领域是制备方法的影响，即浸渍和共沉淀。浸渍法制备的催化剂表现出优异的性能。实验结果表明，铂助剂促进重整反应，铁促进水-气变换反应，钴助剂有利于甲烷化反应。此外，贵金属的加入减少了镍/白云石上的积碳。
Metallic nickel has been selected as a catalyst for biomass gasification because of its activity in biomass steam gasification and tar reduction. The effects of types of promoters such as platinum, cobalt, and iron on biomass gasification were evaluated. The area of interest was the effects of preparation methods, which were impregnation and coprecipitation. Catalyst preparation by the impregnation method showed superior performance. The conclusion can be drawn from the experiments that the platinum promoter enhanced the reforming reaction, iron promoted a water-gas shift reaction, and the cobalt promoter favored a methanation reaction. Moreover, the addition of noble metal reduced carbon deposition on Ni/dolomite.
