Synthesis and study of zeolites modified with cation metals as catalysts for the reaction of oxidative dehydrogenation of naphthenic hydrocarbons

A study of the catalytic activity of modified zeolites in the reaction of selective oxidative dehydrogenation of cyclohexane and methyl cyclohexane demonstrated that catalysts prepared on the basis of natural clinoptilolite modified with Cu 2+ , Zn 2+ , Co 2+ , and Cr 3+ cations exhibit the highest activity in the reactions under consideration. Principles to be used when selecting high-efficiency catalytic systems for the reaction of oxidative dehydrogenation of alicyclic hydrocarbons to the corresponding dienes are formulated.
