Abstract:

This review discussed the use of nano ZSM-5 in naphtha catalytic cracking. The impact of nano ZSM-5 on product selectivity, reaction conversion and catalyst lifetime were compared with micro-sized ZSM-5. The application of nano ZSM-5 not only increased the catalyst lifetime, but also gave more stability for light olefins selectivity. The effects of the reaction parameters of temperature and feedstock on the performance of nano ZSM-5 were investigated, and showed that high temperature and linear alkanes as feedstock improved light olefin selectivity and conversion.
