Abstract: Provided is a process capable of converting the cokes on spent catalysts in a fluid catalytic cracking (FCC) process into synthesis gas. The produced synthesis gas contains high concentrations of CO and H2 and may be utilized in many downstream applications such as syngas fermentation for alcohol production, hydrogen production and synthesis of chemical intermediates. A reducer/regenerator reactor for a fluid catalytic process comprising a chemical looping system to produce synthesis gas is also described.

Abstract: Systems and methods are provided for increasing the yield of products generated during co-processing of biomass oil in a fluid catalytic cracking (FCC) system. The systems and methods can allow for increased yield by reducing or minimizing formation of carbon oxides, gas phase products, and/or coke yields during the co-processing. This can be achieved by adding a hydrogen-rich co-feed to the co-processing environment. Examples of hydrogen-rich co-feeds include high hydrogen content vacuum gas oil co-feed, high hydrogen content distillate co-feed, and/or high hydrogen content naphtha co-feed. Additionally or alternately, various types of fractions that contain a sufficient amount of hydrogen donor compounds can be used to reduce or minimize carbon oxide formation

Abstract: A method may include: providing bio waste stream wherein the bio waste stream comprises at least one bio waste selected from the group consisting of palm oil mill effluent, soapstock, and combinations thereof; introducing the bio waste effluent stream into a fluidized catalytic cracking unit; contacting the bio waste with a catalyst in the fluidized catalytic cacking unit; and cracking at least a portion of the bio waste stream to form cracked products that comprise a cracked product stream.
