摘要：以硅酸四乙酯为硅源，通过水热合成法合成了复合催化剂 ZSM-5/SBA-15，采用 XRD、SEM、TEM、NH 3 -TPD
对其进行了表征。并将其用于生物质（玉米秸秆）的微波催化热解。通过表面响应法，根据 Box-Behnken 实验
原理，对玉米秸秆的非催化热解进行三因素实验，以生物油产率为响应值，温度、升温速率、氮气流速为自变
量，确定最大生物油产率的工艺参数。结果表明，得到的复合催化剂 ZSM-5/SBA-15 不仅具有介孔催化剂 SBA-15
的性质，还兼备微孔催化剂 ZSM-5 的性质，SBA-15 的引入降低了复合催化剂 ZSM-5/SBA-15 的酸性，有利于
促进活性中间体反应。复合催化剂 ZSM-5/SBA-15 的加入对生物油产率影响不大，但对生物油组分具有一定影
响，生物油中烃类和酚类色谱含量（GC）分别达到了 6.42%和 39.65%，比非催化热解都有所增加。

Abstract: Composite catalyst ZSM-5/SBA-15 was prepared by hydrothermal synthesis using tetraethyl
silicate as silicon source and characterized by XRD, SEM, TEM and NH 3-TPD. It was used in microwave
catalytic pyrolysis of biomass (maize straw). Based on the principle of Box-Behnken test, three-factor tests
were carried out on non-catalytic maize straw by surface response method. The yield of bio oil was the
response value, and the temperature, heating rate and nitrogen flow rate were independent variables to
determine the process parameters of the maximum yield of bio oil. The results showed that composite
catalyst ZSM-5/SBA-15 not only had the properties of mesoporous catalyst SBA-15, but also had the
properties of microporous catalyst ZSM-5. The introduction of SBA-15 reduced the acidity of
ZSM-5/SBA-15 and promoted the reaction of active intermediates. The addition of ZSM-5/SBA-15 had
little effect on the yield of bio oil, but had some effect on the components of bio oil. The content of
chromatography (GC) of hydrocarbons and phenols were up to 6.42% and 39.65% in bio oil, higher than
those of non catalytic pyrolysis.
