摘要：
The conversion of ethanol to light olefins has been attracted more attentions since the bioethanol got much developed in recent years. This paper reviewed the advancement of HZSM-5 catalyst for the reaction. The HZSM-5 catalysts modified with metal ion or phosphorus improved the catalytic performance compared to the unmodified catalysts. The loaded components on HZSM-5 decreased the amount of B acid and changed the intensity, the activity of catalysts and selectivity of light olefins were remarkably enhanced by the modification, and the service life was also prolonged. The factors for the reaction and the possible reaction mechanism, were also discussed in the paper. It was pointed out that the production of olefins via ethanol is an alternative route for cracking naphtha.
