How to reduce reaction pressure and hydrogen consumption is a hot and difficult issue for the conversion of biomass to produce alkanes. In this research, vapors from cellulose pyrolysis were converted into alkanes without extra hydrogen source. The effect of content of Au loading, mass ratio of catalyst to cellulose, pyrolysis and catalytic temperature on the production of LCAs was studied. Model compounds were used to explore possible mechanism for the formation of LCAs. At the optimal reaction condition, the highest selectivity and yield of LCAs were 89.2% and 14.4 wt%, respectively, over 1.0% Au/TS-1. Alcohol functional groups are contributed to the formation of LCAs over Au/TS-1.

如何降低反应压力和氢气消耗是生物质转化生产烷烃的热点和难点问题。在这项研究中，纤维素热解产生的蒸汽在没有额外氢源的情况下转化为烷烃。研究了Au负载量、催化剂与纤维素的质量比、热解和催化温度对LCA生产的影响。模型化合物用于探索 LCA 形成的可能机制。在最佳反应条件下，LCA 的最高选择性和产率分别为 89.2% 和 14.4 wt%，超过 1.0% Au/TS-1。醇官能团有助于在 Au/TS-1 上形成 LCA。
