MANUFACTURING METHOD OF LIGHT OLEFINS AND BTX BY USING FCC UNIT FOR TREATING HIGHLY HYDROTREATED VGO-TYPE HEAVY FEEDSTOCK, BY BEING COUPLED WITH CATALYTIC REFORMING UNIT AND AROMATIC COMPLEX FOR TREATING NAPHTHA-TYPE FEEDSTOCK

摘要

The present invention relates to FCC units for treating heavy feedstocks with thickened hydrogen, such as a portion which is not converted when hydrocracking of highly hydrotreated VGO or the same type VGO feedstock thereof is terminated. The feedstocks of the FCC units have degradation properties with respect to light olefins such as ethylene and propylene. A combination of an aromatic complex and FCC is capable of collecting by the aromatic complex of BTX formed in the FCC, and collecting by the FCC from flow in a floor of a column of heavy aromatic groups from the aromatic complex.;COPYRIGHT KIPO 2016
