【摘要】 本文研究了Al-MCM-41的成型工艺。通过氮气吸附-脱附,程序升温脱附（NH₃-TPD）等表征方法,对在不同条件下成型的Al-MCM-41分子筛（CX-Al-MCM-41）进行分析,考察了成型条件对催化剂酸量、孔道结构、侧压强度等的影响。实验结果表明当γ-Al₂O₃用量为30%,聚乙二醇用量为5%,丁烷四羧酸用量为3%,v（10%HNO3）∶m（Al-MCM-41）)=1.0∶1.5时,成型后催化剂的宏观物性最佳,其最大侧压强度可达48 N·cm^-1。更多还原

【Abstract】 The forming process and catalytic properties of Al-MCM-41 were studied.Effects of molding conditions of forming CX-Al-MCM-41 on the catalyst acidity,pore structure and the edgewise compressive strength were investigated by nitrogen adsorption desorption,temperature programmed desorption（NH₃-TPD） and other characterization methods.The results showed that the edgewise compressive strength of CX-Al-MCM-41 was up to48 N·cm^-1when the Al₂O₃ content was 30%,the polyethylene glycol（PEG） was 5%,the polycarboxylic acid dosage was 3% and v（10% HNO₃） ∶ m（Al-MCM-41）) was 1.0∶ 1.5.更多还原
