CATALYST FOR STEAM CRACKING OF HYDROCARBONS, METHOD OF PREPARATION THEREOF, AND A LIGHT OLEFIN PRODUCTION PROCESS UTILIZING THIS CATALYST

摘要

FIELD: petroleum processing and catalysts. ^ SUBSTANCE: invention relates to catalyst for steam cracking of hydrocarbons, which catalyst contains KMgPO4 as catalyst component. Catalyst is prepared by dissolving KMgPO4 precursor in water and impregnating a support with resulting aqueous solution of KMgPO4 precursor or mixing KMgPO4 powder or its precursor with a metal oxide followed by caking resulting mixture. Described is also a light olefin production involving steam cracking of hydrocarbons. ^ EFFECT: increased yield of olefins, reduced amount of coke deposited on catalyst, and stabilized catalyst activity. ^ 21 cl, 4 tbl, 14 cl
