Abstract: A method of improving the uniformity of the contacting of a heavy oil feed with FCC cracking catalyst in the feed zone of an FCC cracking riser in which the heavy oil feed is injected into the catalyst in the riser by means of feed injectors located around the riser, the method comprising minimizing the differences in the temperature profile in the oil/catalyst mixture across the feed zone by varying the oil feed rate to the injectors.

Abstract: A method for removing gas contaminants from flowing solids in a fluid catalytic cracking (FCC) process can include: catalytically cracking a hydrocarbon feedstock in the presence of a catalyst in a riser of a FCC unit to produce a hydrocarbon product; separating the hydrocarbon product from a spent catalyst to produce a hydrocarbon product stream; regenerating the spent catalyst in a regeneration gas comprising oxygen to produce a mixture comprising a regenerated catalyst and a gas contaminant at a first concentration; introducing a stripping gas and the mixture into a regenerated catalyst stripper to produce a regenerated catalyst stream comprising the regenerated catalyst, the stripping gas, and a gas contaminant at a second concentration that is reduced by 50% or greater as compared to the first concentration; and introducing the regenerated catalyst stream to the riser.

Abstract: A method is provided for upgrading a hydrocarbon feed. The method may include contacting a hydrocarbon feed with a catalyst in a fluidized bed reactor; directing a portion of the catalyst from the fluidized bed reactor to a regeneration zone, such that the portion of the catalyst flows in a first direction through the regeneration zone; directing combustion air into the regeneration zone in a counter-flow direction to the first direction, wherein the combustion air is provided at a rate of about 100.05% or less of the stoichiometric air requirement for combusting coke present on the portion of catalyst; regenerating the portion of the catalyst in the regeneration zone to produce regenerated catalyst; and directing a portion of the hydrocarbon feed to combine with the regenerated catalyst downstream of the regeneration zone and lift the regenerated catalyst back to the fluidized bed reactor.
