Method for Benzene Toluene and Xylene from pyrolysis fuel oil

摘要

Provided is a method for manufacturing benzene, toluene, and xylene, comprising: a first step of performing a selective hydrogenation reaction with the entire amount of pyrolyzed fuel oil, which is a by-product generated in a naphtha cracking center, as a raw material; and a second step of performing a hydrocracking reaction of the entire amount of reactants in the first step. According to the present invention, it is possible to solve the high heat of reaction generated during the hydrogenation reaction, suppress the rapid deactivation of a catalyst generated during the hydrocracking reaction with aromatic compounds with at least three rings, and secure an economic effect of not having to add a distillation process separately in order to reduce polycyclic aromatic compounds.
