Abstract: A methodology has been proposed to improve the efficiency of the industrial straight-run gasoline pyrolysis process, in which part of the gasoline deficit is compensated by propane. The procedure consists of two stages. In the first stage, a theoretically substantiated mathematical model of gasoline pyrolysis is applied to determine the operating parameters that maximize the total yield of ethylene and propylene. In the second stage, a mathematical model of propane thermal cracking is used to define the propane feed that provides the maximum yield of target products at the optimal temperature obtained in the first stage (Topt = 1123 K).
