PROCESS FOR MAXIMUM DISTILLATE PRODUCTION FROM FLUID CATALYTIC CRACKING UNITS (FCCU)
摘要
The present invention provides an improved fluidized catalytic cracking process coupled with a two stage regeneration process in which the activity of the circulating catalyst is independently controlled for cracking hydrocarbon feedstocks or the vapors at low severity to produce maximum light cycle oil/distillate in one riser whilst cracking recycle streams comprising heavy cycle oil (HCO), light cracked naphtha (LCN) etc. in a second riser operating at high severity to produce LPG.
