Process for upgrading refinery heavy residues to petrochemicals

摘要

The present invention relates to a process for upgrading refinery heavy residues to petrochemicals, comprising the following steps of:(a) separating a hydrocarbon feedstock in a distillation unit into a to overhead stream and a bottom stream(b) feeding said bottom stream to a hydrocracking reaction area(c) separating reaction products, which are generated from said reaction area of step (b) into a stream rich in mono-aromatics and in a stream rich in poly-aromatics(d) feeding said stream rich in mono-aromatics to a gasoline hydrocracker (GHC) unit,(e) feeding said stream rich in poly-aromatics to a ring opening reaction area.
