摘要：
The stepwise hydrothermal conversion of Pubescens selectively to furans and phenol compounds was investigated in a sealed autoclave reactor. The influence of reaction temperature and reaction time on the product distribution was studied. The results were compared to those from direct pyrolysis process. The residues from Pubescens via hydrothermal route and pyrolytic route were characterized by SEM and component analysis. A new method for obtaining furans and phenols separately through a two-step process was proposed. The first step was suggested performing at a moderate temperature for a shorter time to obtain liquid product with high furan content, while the second step was designed proceeding at a higher temperature for a comparatively longer time to produce more phenol compounds.
