Effect of the Composition of a Nonacid n-Alkane Cyclization Catalyst on Its Physicochemical and Catalytic Properties

Information is presented on the catalysts used for the cyclization of n-alkanes and the features of the relevant reactions, depending on the nature of the binder used for catalyst synthesis. A procedure for the synthesis of nonacid catalysts for the cyclization of n-alkanes is described. The results of instrumental studies and catalytic tests of synthesized catalyst samples are presented. Of the most common commercial binder materials manufactured by SASOL, boehmite Disperal P2 has been found to provide the best combination of mechanical and catalytic properties. The optimum ratio of zeolite KL and the binder in the composition of the n-alkane cyclization catalyst is 70 wt % zeolite and 30 wt % binder. This formulation makes it possible to achieve an optimal combination of mechanical strength and catalytic activity of the catalyst.
