A FLUID CATALYTIC CRACKING PROCESS" ABSTRACT, A method for operating a fluid catalytic cracking unit comprising a regeneration zone and a reaction zone with a relatively reduced temperature in the regeneration zone while processing a high-coke-making hydrocarbon feedstock having a 50 volume percent distillation temperature greater than about 500°F (260°C) which method comprises contacting at conversion conditions the feedstock in a reaction zone with a fluidizable mixture of regenerated cracking catalyst and low-coke-make non-catalytic solid particles comprising, a refractory inorganic oxide in a ratio of low-coke-make solid particles to cracking catalyst from about 1:100 to about 10:1 the …

Why it's free to use
- Granted January 23, 1990. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended January 23, 2007.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
