Abstract:
At low temperatures, C3 and C4 hydrocarbons (equivalent to propane gas) were produced using only water, a solid catalyst, and cellulose, employing no enzymes or expensive, valuable hydrogen. High C3 + C4 yields were achieved using a catalyst doped with Mg as a base site in ZrO2, which has Lewis acid and base properties, supported with Pt, which has high hydrocarbon production capacity. After screening and characterisation of this catalyst using various values of parameters such as the amount of Mg doping and the amount of Pt loading, findings indicated that 1 wt% Pt caused moderate decarbonylation and dehydration, and that the Zr0.5Mg0.5O2- support promoted cellulose degradation by its Lewis acid-base properties. The reaction mechanism was investigated, clarifying the C3 and C4 hydrocarbon formation mechanisms.
