采用愈创木酚作为生物质模型化合物，以ZSM-5为催化剂，在固定床反应器中研究了反应温度、质量空速以及分压对热解产物产率、选择性的影响，并考察了催化剂的积炭情况。结果表明，愈创木酚催化热解的主要产物为酚类，其次是芳香烃。温度对产物分布有显著影响。催化剂适量的积炭有利于提高烯烃和芳香烃的产率。根据愈创木酚催化热解反应产物分布，推测其主要反应为脱除甲氧基形成酚类，进一步芳构化形成芳香烃。本文研究结果为研究生物质催化热解反应机理提供了理论依据。

Catalytic pyrolysis of guaiacol, as a model compound of biomass, was conducted over ZSM-5 in a fixed-bed reactor. The effects of temperature, weight hourly space velocity and partial pressure on the yield and the selectivity of product were investigated and the coked ZSM-5 were characterized. The results indicated that the main products of guaiacol catalytic pyrolysis were phenolic compounds, followed by aromatic hydrocarbons. Temperature has a significant influence on the product distribution. A certain amount of coke deposition on the catalyst is useful in improving the yield of olefins and aromatic hydrocarbons. Based on the product distribution , the catalytic reaction pathway was speculated to be the removal methoxy group to form phenols with further aromatization to form aromatic hydrocarbons. The results provide a theoretical basis for the research of the mechanism of biomass catalytic pyrolysis.
