USE OF METAL-ZEOLITES AS A CATALYST IN REACTION OF OXIDATIVE DEHYDROGENATION OF NAPHTHENES

M.Nagiyev Institute of Catalysis and Inorganic Chemistry, NAS of Azerbaijan zumrud-042425-@mail.ru Received 20.04.2016 Oxidative dehydrogenation of cyclohexane into 1,3-cyclohexadiene and methylcyclohexane into 1-methyl-1,3-cyclohexadiene has been found possible by use of clinoptilolite (CL) {Cu2+ (0.5 mas. %), Zn2+ (0.2 mas. %), Co2+ (0.1 mas. %), Cr3+ (0.1 mas. %)} and CL {Co2+ (0.5 mas. %), Cr3+ (0.25 mas. %)} heterogenic catalysts, prepared by ion-exchange, accordingly. By analyzing experimental data and taking into account bonding energies of exchange cations with dissociative adsorbed oxygen the active centers consisting of components of the catalyst have been grouped and reaction paths have been elucidated. The kinetic model worked out by taking into account these active centers, is presented
