Method of making a zeolite catalyst and using the catalyst in a hydrocarbon conversion process

摘要

A hydrocarbon conversion process in which the rate of coke formation is reduced and aromatics and lower olefins yield is increased by the use of an improved zeolite catalyst that comprises a silylated, zeolite material preferably treated with steam. Another embodiment includes the use of an improved zeolite catalyst that comprises silylated, acid treated zeolite material.
