US 2013/0253242 A1 · METHOD FOR PRODUCING HIGH-ADDED-VALUE AROMATIC PRODUCTS AND OLEFINIC PRODUCTS FROM AN AROMATIC-COMPOUND-CONTAINING OIL FRACTION

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 feedstock for aromatic production and so make stable supply and demand, 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 separation step and a transalkylation step, and optionally also comprising a recirculation step.

Dependent claims

A method of producing aromatic products and olefinic products from an aromatic compound-containing oil fraction, comprising the steps of:

(a) hydroprocessing an aromatic compound-containing oil fraction in the presence of a catalyst to partially saturate components in the oil fraction;
(b) catalytic cracking the components partially saturated in step (a) in the presence of a cracking catalyst;
(c) separating the components cracked in step (b) into (i) benzene, toluene, xylene and aromatic components of 9 or more carbon atoms, (ii) olefin components and (iii) a residual oil fraction;
and
(d) carrying out transalkylation of benzene, toluene and aromatic components of 9 or more carbon atoms separated in step (c).
