Abstract

The catalytic activity of the modified zeolites in the reaction of selective oxidative dehydrogenation of cyclohexane to cyclohexadiene-1,3 has been investigated. It has been found that, the catalyst, Cu Zn Co Cr-clinoptilolite (Cu2+—0.5%; Zn2+—0.2%; Co2+—0.1%; Cr3+—0.1%) shows the most activity in this reaction. A kinetic scheme of the mechanism of the reaction has been suggested and on the basis of this scheme, kinetic model of the process has been developed. Numerical values of the kinetic parameters were calculated.

Summary

Introduction

The alicyclic dienic hydrocarbons are the raw material for the synthesis of various classes of polyfunctional compounds. (2015) Selection of Active Modified Zeolite Catalyst and Kinetics of the Reaction of Selective Oxidative Dehydrogenation of Cyclohexane to Cyclohexadiene 1,3. Oxidative dehydrogenation of naphthenes for obtaining of alicyclic dienichydrocarbons refers to poorly studied heterogeneous catalytic reactions proceed with participation of oxygen. From this point of view, the synthesis of highly active and selective zeolite-based catalyst for the selective oxidative dehydrogenation of cyclohexane to cyclohexadiene-1,3 is of great theoretical and practical importance. This paper presents the results of studies of oxidative dehydrogenation of cyclohexane with molecular oxygen in order to identify the conditions of selective formation of cyclohexadiene-1,3 in the presence of modified zeolite catalysts and results of investigation of the kinetics of the reaction
