Systems and methods for enhancing the processing of hydrocarbons in a FCC unit by introduction of the coked FCC catalyst from the FCC reactor and a renewable feedstock to the FCC regenerator to facilitate regeneration of the coked FCC catalyst. The renewable feedstock can contain biomass-derived pyrolysis oil. The biomass-derived pyrolysis oil and coke from the coked FCC catalyst are oxidized by oxygen to provide a regenerated catalyst that is recycled to the FCC reactor.

Methods and systems for enhancing processing of hydrocarbons in a fluid catalytic cracking unit using a renewable additive

Methods and systems for enhancing hydrocarbon processing in a fluid catalytic cracking (FCC) unit by introducing a renewable feedstock into the FCC unit at alternative locations of the FCC unit to increase residence time and promote a higher degree of FCC feedstock cracking. The renewable feedstock may include one or more of plastic-derived pyrolysis oil or plastic-derived hydrocarbons, biomass-derived pyrolysis oil, municipal waste-derived pyrolysis oil, vegetable based feedstock, animal fat feedstock, algae oil, sugar-derived hydrocarbons, or carbohydrate-derived hydrocarbons. The alternative locations of the FCC unit may include one or more of FCC reactor catalyst bed, an FCC catalyst stripper, at a nozzle located downstream of a gas oil injection point, or at a nozzle located upstream of the gas oil injection point.

Systems and methods are disclosed for enhancing the processing of hydrocarbons in a FCC unit by introduction of fluidized plastic at one or more locations of the FCC unit. In an embodiment, the method may include passing a coked FCC catalyst from a cyclone of the FCC unit to a regenerator. The method may include introducing at least oxygen and a fluidized plastic into the regenerator. The method may include combusting a combination of the fluidized plastic and a coke from the coked FCC catalyst in the regenerator, thereby to oxidize via the oxygen and produce a regenerated FCC catalyst and a flue gas. The method may include supplying the regenerated FCC catalyst from the regenerator to a riser of the FCC unit to crack the gas oil supplied to the riser of the FCC unit.

The invention provides an improved system for separation technology intended to reduce unwanted catalyst/thermal reactions by minimizing contact of the hydrocarbons and the catalyst within the reactor.

FCC yield selectivity improvements in high containment riser termination systems

An injection of a small amount of sweet vacuum residue into an FCC feed consisting of sweet gas oil combined with shape selective catalyst additives technology improves propylene and butylene yields significantly.
