中文摘要:
      通过表面响应法,以Box-Behnken试验原理,对生物质(玉米秸秆)的非催化热解进行三因素试验,其中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进行催化热解。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,并进行玉米秸秆的微波催化热解产物分析。通过XRD、SEM、TEM、NH3-TPD进行催化剂表征,得到复合催化剂不仅具有介孔催化剂SBA-15的性质,且兼备微孔催化剂ZSM-5的性质。通过GC-MS分析,复合催化剂ZSM-5/SBA-15的加入,相比非催化热解烃类收率(6.42%)和酚类收率(39.65%)都有所增加。
英文摘要:
      Through the surface response method, based on the Box-Behnken test principle, a three-factor test was carried out on non-catalytic pyrolysis of biomass (corn straw), which the bio-oil yield is the response value, and the temperature, heating rate and nitrogen flow rate are independent variables. Process parameters to determine the maximum bio-oil yield for catalytic pyrolysis. Using tetraethyl silicate as the silicon source, a composite catalyst ZSM-5/SBA-15 was synthesized by post-synthesis method, and the microwave catalytic pyrolysis product analysis of corn straw was carried out. The catalysts were characterized by XRD, SEM, TEM, NH3-TPD, and draw conclusions the composite catalyst not only had the properties of mesoporous catalyst SBA-15, but also had the properties of microporous catalyst ZSM-5. Through GC-MS analysis, the addition of the composite catalyst ZSM-5/SBA-15 increased the content of hydrocarbon (6.42%) and phenol (39.65%) compared with that of non-catalytic pyrolysis.
