CATALYST FOR STEAM CRACKING OF HYDROCARBONS, METHOD OF PREPARATION THEREOF, AND A LIGHT OLEFIN PRODUCTION PROCESS UTILIZING THIS CATALYST Russian patent published in 2007 - IPC B01J27/18 C10G11/02 B01J37/02 B01J37/08 

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.
