Abstract

The present invention relates to a method for manufacturing aromatic products (benzene / toluene / xylene) and olefinic products from an aromatic-compound-containing oil fraction, whereby it is possible to substitute naphtha as a starting material for aromatic production and so arrange stable water supply, and it is possible to substantially increase the yield of high-added-value olefinic and high-added-value aromatic components, by providing a method for manufacturing olefinic and aromatic products from light cycle oil comprising a hydrogen-processing reaction step, a catalytic cracking step, an isolation step and a transalkylation step, and optionally also comprising a recirculation step.

Description

technical field [0001] This invention relates to a process for the production of valuable aromatic products (benzene / toluene / xylene) and olefinic products from hydrocarbon oils containing aromatic compounds. Background technique [0002] Worldwide, demand for aromatics (eg, benzene, toluene, and xylene) is growing by an average of 4-6% per year. That is, the demand for aromatic products is growing so rapidly that the growth rate of the demand for aromatics is about twice the growth rate of GDP and three times the growth rate of the demand for petroleum products. In particular, this increase in demand is driven by the increase in demand for aromatics in China. [0003] Typically, aromatic products (benzene / toluene / xylene) are produced by hydrotreating and extracting pyrolysis gasoline in a naphtha cracking center with The main base oil fractions (such as ethylene, propylene, etc.) are produced together; or the reformate obtained from the catalytic naphtha reforming process ...
