An alternative technology of benzene alkylation with propylene is proposed at OJSC Omsk rubber. The effectiveness of aluminum chloride catalyst replacement is evaluated on sulfocationites. A discrete supply of propane-propylene fraction to the alkylation reactor is proposed. The mathematical model of benzene alkylation process with propylene using the sulfocationites catalysts was developed. Mathematical model of the process was developed in the program environment AspenTech. The numerical values of the rate constants were determined. An adequate process model allow carrying out numerical experiments on the variation of the basic reagents relations reactions.
