Oxidative Conversion of Lower Olefins and Paraffins Over the Modified Zeolite Catalysts

Abstract

With the purpose of development of high efficiency catalysts for reactions of the oxidative conversion of lower olefins and paraffins into the desired products of petrochemical industry it has been synthesized by ion exchange method a range of the metalzeolite catalysts on the basis of synthetic (NaY) and natural (pure and dealuminated clinoptilolite and mordenite) zeolites and the cations of different metals. It has been established that the metalzeolite catalysts prepared on the basis of synthetic zeolite NaY shows relatively high activity in the oxidative conversion of ethylene and propylene into acetaldehyde and acetone accordingly. It has been also synthesized a highly effective metalzeolite catalysts for the processes: oxidative conversion of methane into ethylene; oxidative conversion of propane into acetaldehyde and formaldehyde; oxidative conversion of methane to ethylene and acetylene; oxidative conversion of methane to 1,4-butanediol
