Method for producing raw material of naphtha cracking center

Abstract

A method for producing a raw material of a naphtha cracking process, the method including: preparing a pyrolysis composition including a polyolefin or a blend including the polyolefin and a hydrogen donor; and pyrolyzing the pyrolysis composition to obtain pyrolysis products. The method results in an increase in the amount of gasoline included in the pyrolysis product, while significantly decreasing the amount of a heavy hydrocarbon having 23 or more carbon atoms, which is not appropriate as the raw material of a naphtha cracking center. Thus, a yield of the pyrolysis fraction can be further increased while obtaining a high-quality pyrolysis fraction.
