Abstract: A jet boiling range composition is provided with an unexpected distribution of carbon chain lengths for the hydrocarbons and paraffins in the composition. The hydrocarbon composition corresponds to a jet boiling range composition that includes 40 wt % or more of hydrocarbons and/or paraffins that have carbon chain lengths of 17 carbons or 18 carbons. Additionally or alternately, the hydrocarbon composition can contain 45 wt % or less of C14-C17 hydrocarbons and/or paraffins. This unexpected distribution of carbon chain lengths in a jet boiling range composition can be achieved for a composition that has a freeze point of −40° C. or lower and a flash point of 38° C. or higher. Optionally, the jet boiling range composition can also have a T10 distillation point of 205° C. or less (such as down to 150° C.) and a final boiling point of 300° C. or less

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: 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.

Abstract: Methods of refining a whole crude oil stream. The methods involve first processing the crude either through a hydrotreating reactor comprising a dewaxing reactor bed or a flash evaporation separator. The treated streams are then further processed through a demetalization reactor bed, a hydroprocessing reactor bed, or both. The stream can then be still further processed via additional hydrotreating, distillation, or both.

Abstract: Systems and methods are provided for co-processing of biomass oil with mineral coker feeds in a coking environment. The coking can correspond to any convenient type of coking, such as delayed coking or fluidized coking. The biomass oil can correspond to biomass oil with a molar ratio of oxygen to carbon of 0.24 or less on a dry basis. Such types of biomass oil can be formed from pyrolysis methods such as hydrothermal pyrolysis, and are in contrast to biomass oils formed from pyrolysis methods such as fast pyrolysis. By using a biomass oil with a molar ratio of oxygen to carbon of 0.24 or less, improved yields of light coker gas oil can be achieved in conjunction with a reduction in the yield of heavy coker gas oil.

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.
