Enhanced distillate oil recovery from thermal processing and catalytic cracking of biomass slurry
A method for thermal processing and catalytic cracking of a biomass to effect distillate oil recovery can include, particle size reduction. slurrying the biomass with a carrier fluid to create a reaction mixture, slurrying a catalyst with a carrier fluid to create a catalyst slurry, heating the reaction mixture and/or the catalyst slurry, and depolymerizing the reaction mixture with the catalyst. The reaction mixture can undergo distillation and fractionation to produce distillate fractions that include naphtha, kerosene, and diesel. In some embodiments, thermal processing and catalytic cracking includes vaporization of the biomass followed by distillation and fractionation. In some embodiments, a resulting distillate can be used as a carrier fluid. In some embodiments, the method can include desulfurization, dehydration, and/or decontamination.

PROCESS FOR REGENERATING CATALYST FROM A FLUIDIZED CATALYTIC PROCESS AT HIGH PRESSURE
A process for regenerating catalyst from a fluidized catalytic process comprising is disclosed. The process comprises providing an oxygen stream and a preheated carbon dioxide recycle stream and mixing the oxygen stream and the preheated carbon dioxide recycle stream to provide a carbon dioxide rich oxidation stream. The carbon dioxide rich oxidation stream is passed to a regenerator unit to provide a carbon dioxide rich flue gas stream. One or more of a sulfur-containing compound, a nitrogen-containing compound, or both in the carbon dioxide rich flue gas stream is reacted with a reactant in a decontamination reactor to form a reactor effluent stream comprising reactant salt. The reactor effluent stream is filtered to remove the reactant salt and catalyst fines to produce a filtered reactor effluent stream. A carbon dioxide recycle stream is taken from the filtered reactor effluent stream.
