The dependence of the yield and composition of the heavy pyrolysis resin on the initial hydrocarbon feedstock and the process conditions is investigated. The variation of technological parameters within certain limits leads to a change in the content of low molecular weight olefins in the gaseous pyrolysis products, as well as the qualitative and quantitative composition of by-product liquid products. As a result of the research, the optimum process conditions for the pyrolysis of straight-run gasoline were determined, which, with the maximum conversion of hydrocarbons to low-molecular-weight olefins, significantly increases the yield of heavy resin containing a wide fraction of naphthalene, biphenyl, indene and their alkyl derivatives. It is shown that when treating by-products containing valuable hydrocarbons as target products and combining the technological mode of pyrolysis and their composition, it is possible to achieve along with the maximum yield of low molecular weight olefins, a significant yield of heavy pyrolysis resin and qualitative changes in its composition.
