EFFECT OF PROMOTER METALS ON CATALYST ACTIVITY IN PROPANE-BUTANE FRANCOATION

Abstract

Abstract The work studies the effect of the composition of active components on the rate of the reaction of aromatic hydrocarbons from the propane-butane fraction. The effect of various factors on the catalytic activity of selected catalysts in the reaction of aromatic hydrocarbons production was evaluated. The studies were conducted in a flow differential catalytic device in the stationary phase of the catalyst (catalyst volume 6 cm3), at 450-650C, at normal atmospheric pressure (P = 0.1 MPa), and under conditions of a volumetric flow rate of the initial gas mixture of 600-1000 h-1. Experiments were conducted with different amounts of zirconium prepared on the basis of molybdenum. In addition, the process of obtaining aromatic hydrocarbons by catalytic aromatization of propane-butane fraction by introducing spirit and gallium oxides into a composite catalyst based on Zr-Mo was analyzed. The effect of metal oxides used in the preparation of catalysts on the aromatization process and coking was studied.
