Abstract

Using the benzene alkylation reaction with propylene, the catalytic properties of heterogeneous catalysts are compared under conditions of simultaneous action of permanent deactivating factors (atmospheric pressure, increased volume feed rate) on the samples under study. For a comparative evaluation of the tested catalysts, a mathematical analysis of the experimental data on the concentration of the desired alkylation product vs. the time of the catalyst operation was carried out, and a corresponding empirical formula was derived. To compare the activity of catalysts, the power coefficient of the function was proposed as a catalyst activity factor f. A relationship between the value of this factor and the rate of deactivation of the catalyst under the conditions of the experiments was derived.
