Catalytic cracking of cyclohexane (CHA) over ZSM-5, Beta, and USY zeolite catalysts was examined in a ifxed lfuidized bed reactor (ACE) at 773 K. The adsorption of cyclohexane in ZSM-5, Beta, and USY catalysts was investigated by IR spectroscopy. The IR results demonstrated that the zeolite structure has a remarkable inlfuence on adsorption. Beta zeolite has stronger adsorption of cyclohexane than ZSM-5 and USY zeolites. During the cracking of cyclohexane, path I (cyclohexane→methycyclopentane→light oleifns) and path II (cyclohexane→cyclohexene→light oleifns) were found as two important reaction pathways to produce light oleifns. A mixture of ZSM-5 and Beta zeolites is better suited for path I, and a combination of ZSM-5 and USY zeolites is suitable for path II. When pathway I and pathway II had the same proportion in cyclohexane conversion, pathway II would be a better choice for light oleifns production.
