摘要：
The present invention relates to the FCC units processing heavy feedstocks enriched with hydrogen, such as for example a highly hydrotreated VGO, or the unconverted part at the end of hydrocracking this same type of VGO feedstock, feedstocks which have the characteristic of cracking to light olefins such as ethylene and propylene. The integration of an FCC with an aromatic complex allows the recovery by the aromatic complex of the BTX formed in the FCC, and the recovery by the FCC from the flow at the bottom of the column, of heavy aromatics from the aromatic complex.
