HYDROCRACKING PROCESS TO MAXIMIZE DIESEL WITH IMPROVED AROMATIC SATURATION

摘要

A VGO stream is initially hydrocracked in a hydrocracking reaction zone with in an integrated hydroconversion process. Effluent from the hydrocracking reaction zone is combined with a light aromatic-containing feed stream, and the blended stream hydrotreated in a hydrotreating reaction zone. Heat exchange occurs between the hydrocracking reaction zone and the hydrotreating reaction zone, permitting the temperature control of the initi al hydrocracking zone. The integrated reaction system provides a single hydrogen supply and recirculation system for use in two reaction processes.< /SDOAB>
