摘要：An integrated hydrotreating process which produces a high quality feed for the FCC to maintain sulfur in FCC gasoline to a level lower than 30 ppm from a high boiling feedstock and an ultra low sulfur diesel stream preferably less than 10 ppm from a cracked diesel boiling material. The high boiling feedstock is firstly hydrotreated to reduce the concentration of heterogeneous compounds which produces lower boiling hydrocarbonaceous compounds boiling in the diesel range and the resulting hydrotreated high boiling feedstock is separated in a high pressure stripper. The resulting hydrocarbonaceous compounds boiling in the diesel range together with other cracked and/or straight run material in the diesel boiling range are further hydrotreated in an integrated second hydrotreating zone to meet ultra low sulfur diesel specifications and a high cetane index.
