Abstract: Systems and methods are provided for improving product yields and/or product quality during co-processing of fast pyrolysis oil in a fluid catalytic cracking (FCC) reaction environment. The systems and methods can allow for co-processing of an increased amount of fast pyrolysis oil while reducing or minimizing coke production for a feedstock including fast pyrolysis oil and a conventional FCC feed. The reducing or minimizing of coke production can be achieved in part by adding a low molecular weight, non-ionic surfactant to the mixture of fast pyrolysis oil and conventional FCC feed.

Abstract: In various aspects, systems and methods are provided for operating an oxygen-fired catalyst regenerator with flue gas recycle and CO2 capture. An oxygen-fired catalyst regenerator contrasts with an air-fired regenerator. The oxygen-fired catalyst regenerator substantially reduces nitrogen within the system, which facilitates CO2 capture by reducing the energy required to capture CO2. In various aspects, a first portion of the regenerator flue gas is passed to a CO2 capture system and a second portion is recycled to the regenerator. Before the flue gas is recycled or diverted to the CO2 capture, it is passed to various processes that remove and/or reduce SOx, NOx, particulate, and water content. In various aspects, a portion of the treated flue gas may be combined with substantially pure O2 and recycled to the regenerator.

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: The present disclosure provides methods and systems for co-processing a hydrocarbon feed in an FCC system with a second feed of a biomass-derived pyrolysis oil and a third feed of a plastic-derived pyrolysis oil and/or lubricant. A method of co-processing fluid catalytic cracking feeds, includes: introducing a hydrocarbon feed to a fluid catalytic cracking reactor, wherein the hydrocarbon feed comprises hydrocarbons; introducing a biomass feed to the fluid catalytic cracking reactor wherein the biomass feed comprises a biomass-derived pyrolysis oil; introducing a waste feed to the fluid catalytic cracking reactor, wherein the waste feed comprises a plastic, a plastic-derived pyrolysis oil, a lubricant, or a combination thereof; and reacting at least the hydrocarbon feed, the biomass feed, and the waste feed in the presence of one or more fluid catalytic cracking catalysts in the fluid catalytic cracking reactor to produce cracked products.

Abstract: Systems and methods are provided for expanding the operating envelope for an FCC reaction system while also reducing or minimizing the net environmental CO2 emissions associated with the FCC reaction system and/or the resulting FCC products. In some aspects, reducing or minimizing net environmental CO2 emissions can be achieved during processing of unconventional feeds, such as feeds that are traditionally viewed as having insufficient tendency to coke in order to maintain heat balance within an FCC reaction system. In other aspects, this can correspond to expanding the production of diesel within an FCC reaction system by modifying the reaction conditions in a manner that can cause a reaction system to fall out of heat balance (relative to the heat needed to maintain a target operating temperature) even when using conventional feeds.
