摘要:

采用等体积浸渍法制备Mo/ZSM-5催化剂,并应用于生物质快速热解制备生物油。采用Py-GC/MS装置,重点研究了Mo负载量、反应温度、反应时间和催化剂与木粉质量比等参数对生物油产率和组成的影响规律。实验结果表明,与纯木粉热解相比较,ZSM-5和Mo/ZSM-5催化作用下生物油的产率大幅提高;在反应温度为600℃、反应时间为25 s、催化剂与木粉质量比为10/1的条件下,10Mo/ZSM-5催化作用下生物油中芳香烃类化合物的产率和相对含量达到最大值。根据生物油产率和组成的变化,可以得出Mo负载的ZSM-5催化剂强化促进酸类、醛酮类等含氧化合物转化为芳香烃类化合物,有效实现了生物质热解生物油品质的提升。

Abstract:

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.
