Fluid catalytic cracking of renewable feedstocks

A system for producing a renewable fuel product, the system comprising:

• a fractionation column configured to receive a flow of feedstock into one or more injection ports and to preheat the flow of feedstock, the feedstock comprising a renewable fuel;
• and
• a fluidized catalytic cracker having a reactor section and a regenerator section, the reactor section comprising a riser and a reactor, the reactor section configured to receive a flow of the preheated feedstock, the riser configured to receive a flow of regenerated catalyst from the regenerator section and to direct the regenerated catalyst to the reactor,
• wherein the flow of the preheated feedstock is contacted with the regenerated catalyst within the reactor section, thereby converting at least a portion of the preheated feedstock into a first product stream and converting at least a portion of the regenerated catalyst to spent catalyst.

A method of producing a renewable fuel product, the method comprising:

• optionally pretreating a renewable feedstock;
• optionally hydroprocessing the pretreated renewable feedstock;
• preheating at least a portion of the renewable feedstock via direct or indirect contact with an FCC reactor product stream from a fluidized catalytic cracker;
• optionally further heating the preheated renewable feedstock;
• feeding the preheated renewable feedstock into a reactor section of the fluidized catalytic cracker such that at least a portion of the preheated renewable feedstock is contacted with an FCC catalyst, thereby producing the FCC reactor product stream;
• feeding a petroleum-derived coke precursor material into the reactor section;
• and
• feeding the FCC reactor product stream to a fractionator to preheat the at least a portion of the renewable feedstock and to fractionate the FCC reactor product stream into two or more fraction product streams,
• wherein the renewable feedstock comprises one or more of a plant-derived oil, a plant-derived fat, an animal-derived oils, an animal-derived fat, free fatty acids, and algal oils,
• wherein hydroprocessing the pretreated feedstock includes one or more of hydrotreating, hydrocracking, hydrodeoxygenation, hydrodenitrification, hydrodesulfurization, isomerization, and hydroisomerization.
