Recent advances in naphtha catalytic cracking by nano ZSM-5: A review

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.

Graphical AbstractApplication of nano ZSM-5 in naphtha catalytic cracking results in better conversion, longer lifetime and higher selectivity for olefins compare to micro ZSM-5. It is also indicated that altering reaction temperature and feedstock can change the conversion and the selectivity of catalyst.Figure optionsDownload full-size imageDownload as PowerPoint slide
