Abstract: Systems and methods are provided for integrating a fluidized coking process, optionally a coke gasification process, and processes for production of additional liquid products from the coking and/or gasification process. In some aspects, the integrated processes can allow for conversion of olefins generated during a fluidized coking process to form additional liquid products. Additionally or alternately, in some aspects the integrated processes can allow for separation of syngas from the flue gas/fuel gas generated by a gasifier integrated with a fluidized coking process. This syngas can then be used to form methanol, which can then be converted in a methanol conversion process to form heavier products. In such aspects, olefins generated during the fluidized coking process can be added to the methanol conversion process to improve the yield. Additionally, in various aspects, the off-gas from the integrated conversion process can be used as an additional paraffin feed that can be recycled to one of the heat integration conduits in the fluidized coker for additional generation of olefins. This can provide a further increase in liquid yields using a carbon source (C4− paraffins) that is conventionally viewed as a low value product from coking.

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 adding a heated stream of light hydrocarbons to a fluidized coking environment to improve liquid product yield and/or reduce coke production. The light hydrocarbons can correspond to C1-C10 hydrocarbons and/or hydrogen. The light hydrocarbons can be heated so that the light hydrocarbons are exposed to an activation temperature of 535° C. to 950° C. and/or an activation temperature higher than the temperature in the coking zone by 50° C. or more for an activation time prior to entering the fluidized coking reactor and/or the coking zone in the fluidized coking environment.

Abstract: Systems and methods are provided for integrating a fluidized coking process with a catalyst-enhanced coke gasification process. The catalyst for the gasification process can correspond to calcium oxide, a thermally decomposable calcium salt, a potassium salt such as potassium carbonate, or a combination thereof. Examples of suitable calcium salts can include, but are not limited to, calcium hydroxide, calcium nitrate, and calcium carbonate. The calcium oxide, potassium salts, and/or thermally decomposable calcium salts can be introduced into the integrated system, for example, as part of the feed into the coker. It has been unexpectedly discovered that using catalytic gasification as part of an integrated fluidized coking and gasification process can result in an overhead gas stream from the gasifier with increased energy content and/or overhead gas pressure.

Abstract: A method is provided for upgrading a hydrocarbon feed. The method may include contacting a hydrocarbon feed with a catalyst in a fluidized bed reactor; directing a portion of the catalyst from the fluidized bed reactor to a regeneration zone, such that the portion of the catalyst flows in a first direction through the regeneration zone; directing combustion air into the regeneration zone in a counter-flow direction to the first direction, wherein the combustion air is provided at a rate of about 100.05% or less of the stoichiometric air requirement for combusting coke present on the portion of catalyst; regenerating the portion of the catalyst in the regeneration zone to produce regenerated catalyst; and directing a portion of the hydrocarbon feed to combine with the regenerated catalyst downstream of the regeneration zone and lift the regenerated catalyst back to the fluidized bed reactor.
