LEARNING OF EFFICIENCY OF USE OF ZEOLITIC MATERIALS AS COMPONENTS OF CATALYSTS FOR THE HYDROISOMERIZATION OF <i>N</i>-ALKANES
The possibility of using three different zeolite materials (ZSM-5, ZSM-23, SAPO-11) as the acid component a bifunctional hydroisomerization catalyst of normal alkanes was investigated. The comparative analysis of physicochemical properties of the catalyst systems was presented. The catalytic activity was studied in a laboratory using a model feed - hexadecane. Laboratory test results show that catalyst samples prepared using zeolite materials with dimensional channel structure and a predominance of weak acid sites (ZSM-23, SAPO-11) have a high selectivity to the isomers in the hydroisomerization of n -alkanes.
