摘　　要：以正庚烷为模型化合物,在固定床连续微型反应器装置上考察了催化剂的酸量、酸强度分布以及沸石含量对其在芳构化反应过程的影响。试验结果表明,ZSM-5沸石催化剂具有很好的芳构化反应活性,其芳构化反应活性不仅取决于催化剂的酸量和金属活性中心数,而且与催化剂上B酸位的分布密切相关,尤其是B酸位之间的距离。Using n-heptane as a model compound, the influence of acid amount, acid strength distribution and zeolite content of catalysts on the aromatization process was investigated by a continuous fixed-bed micro-reactor system. Results show that ZSM-5 catalysts exhibit excellent aromatization activity. Its aromatization activity not only depends on the catalyst acidity and the amount of metal active sites, but also closely relates with the Bronsted（B）acid sites distribution,especially the distance between B acid sites.
