METHOD FOR PRODUCING HIGH-ADDED-VALUE AROMATIC PRODUCTS AND OLEFINIC PRODUCTS FROM AN AROMATIC-COMPOUND-CONTAINING OIL FRACTION

摘要

METHOD FOR PRODUCING HIGH-ADDED-VALUE AROMATIC PRODUCTS AND OLEFINIC PRODUCTS FROM AN AROMATIC-COMPOUND-CONTAINING OIL FRACTION5The present invention relates to a method for manufacturing aromatic products (benzene/toluene/xylene) and olefinic products from an aromatic-compound-containing oilM 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.
