摘要：
The Mo/ZSM-5 catalyst was prepared by an equal volume impregnation method and applied to the rapid pyrolysis of biomass to prepare bio-oil. The effects of Mo loadings, reaction temperature, reaction time and catalyst/biomass mass ratio on the yields and composition of bio-oils were researched. Compared to the pyrolysis of sawdust, the yields of bio-oils were greatly increased by ZSM-5 and Mo/ZSM-5 catalysts. Under the reaction condition of T=600℃, t=25 s, catalyst/biomass mass ratio=10/1, the yields and amounts of aromatic hydrocarbons in bio-oil reached the maximum by 10Mo/ZSM-5 catalysts. According to the variations of products in bio-oils, Mo/ZSM-5 catalysts promoted the conversion of oxygenated compounds, such as acids, aldehydes and ketones, into aromatic hydrocarbons, which could effectively upgrade the bio-oils. © All Right Reserved.
