CONJUGATED CATALYTIC EFFECT OF THE COMPONENTS OF Ni/MOR/SO_{4} 2- -ZrO_{2} ON THE CONVERSION OF A MIXTURE OF STRAIGHT-RUN GASOLINE AND AROMATIC HYDROCARBONS AT ATMOSPHERIC PRESSURE OF HYDROGEN

Abstract

The paper presents the results of studying the conversion of a mixture of toluene: straight-run gasoline (T:SRQ)= 1:1, modeling the conversion of reforming gasoline, in the presence of a composite catalytic system Ni/HMOR/SO42/ZrO₂ (CCS) and its components, activating the joint hydrogenation of aromatic hydrocarbons and isomerization disproportionate transformation of C₈+ components. It has been established that at atmospheric pressure, Т=180⁰С and the ratio Н2/hydrocarbon =8, the transformation of the mixture with the participation of CCS is characterized by 76.8% conversion of toluene, 77.1% conversion of С₈+ components of SRQ and the 44.7% yield of isomeric С₅-С₇ alkanes. Based on a comparison of the results of the T:SRQ conversion in the presence of individual CCS components and their mechanical mixture, a conclusion was made about the conjugated nature of the effect of the CCS components on the process and a mechanism for the occurrence of catalytic synergy in the process of conversion of the T:SRQ mixture was proposed.
