摘    要:采用后合成法制备出固体碱催化剂KOH/SBA-15,利用X射线衍射法(XRD)、N2吸附-脱附(BET)、透射电镜(TEM)、化学吸附剂表面碱性测定(COz—TPD)等对其进行表征。考察了其在大豆油酯交换反应制备生物柴油中的催化性能。结果表明,在相同反应条件下,与CaO/SBA-15和MgO/SBA-15相比,KOH/SBA-15在催化活性和孔扩散上都具有较大的优越性,催化制备生物柴油产率最高(83.56%)。

关 键 词:KOH  SBA-15  固体碱催化剂  表征  催化性能

Abstract:SBA-15 was modified by introducing an active component by post-synthetic method for pre- paring a solid base catalyst KOH/SBA-15. Characterization was carried out by XRD, BET, TEM and CO2-TDP to understand the nature. KOH/SBA-15 catalytic performance on transesterification to pro- duce biodiesel from soybean oil was studied. In the same reaction conditions, compared to CaO/SBA-15 and MgO/SBA-15, (15%)KOH/SBA-15 showed the highest yield of biodiesel, due to its favorable su- periority on catalytic activity and pore diffusion.
Keywords:KOH/SBA-15  Solid base catalyst  Characterization  Catalytic performance
