  • PROCESS FOR MAXIMUM DISTILLATE PRODUCTION FROM FLUID CATALYTIC CRACKING UNITS (FCCU)
    Publication number: 20130130889
    Abstract: 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.

  • Process and apparatus for separating fluidized cracking catalysts from hydrocarbon vapor
    Patent number: 5837129
    Abstract: The invention is a process and apparatus for rapidly and efficiently separating a fluidized catalytic cracking mixture into cracking catalysts and hydrocarbon vapor. The invention decreases the production of unwanted hydrocarbon byproducts by decreasing the contact time between the separated hydrocarbon vapor and the cracking catalyst.
    Type: Grant
