Microwave-assisted catalytic pyrolysis of biomass is a promising technology to obtain hydrocarbon rich fuel oil. In consideration of this method, HZSM-5 is currently recognized as a catalyst with a good effect. However, given the small pore diameter and easy coking of HZSM-5, the catalytic upgrading of bio-oil is limited to a certain extent. In this study, MCM-41 and HZSM-5 were used for joint catalysis to explore the effect of catalytic temperature, the ratio of two catalysts, and the ratio of soybean soapstock and catalysts on the pyrolysis products. The optimal reaction conditions included the following: catalytic temperature, 400 °C; MCM-41/HZSM-5 ratio, 1:1; feedstock/catalyst ratio, 2:1. The results showed that MCM-41 could effectively alleviate the coking of HZSM-5, and the use of both catalysts reduced the bio-oil yield but effectively improved the selectivity of monocyclic aromatic hydrocarbons in bio-oil, thus increasing the value of bio-oil.

微波辅助生物质的催化热解是一种获得富烃燃料油的有前途的技术。考虑到该方法，HZSM-5目前被认为是具有良好效果的催化剂。然而，由于HZSM-5的孔径小且易于结焦，生物油的催化提质在一定程度上受到限制。在这项研究中，MCM-41和HZSM-5用于联合催化，以探索催化温度，两种催化剂的比例以及大豆皂液和催化剂的比例对热解产物的影响。最佳反应条件包括：催化温度400°C; MCM-41 / HZSM-5比例为1：1；原料/催化剂比为2：1。结果表明，MCM-41可以有效减轻HZSM-5的焦化，
