Abstract: The invention provides extraction of immobilized oil from an oil-containing feed using a food grade solvent. The food grade solvent may include ethyl acetate or ethyl lactate. The solvent may also include an ethanol co-solvent with the ethyl acetate or ethyl lactate. The solvent may be recaptured within the system and reused in the process.

Abstract: The invention provides systems and methods for converting biomass into syngas using a pressurized multi-stage progressively expanding fluidized bed gasifier to eliminate or reduce the formation of methane, volatiles such as BTX, and tars. The gasifier may include a reactive stage that may receive a biomass feed through a feed line and oxygen through an oxygen feed line. The gasifier may also include a fluidized bed section that may be configured to receive the reaction products from the first stage, mix them and perform fluidized bed activity. A gasifier may also have a disengagement section that may be configured to separate fluidized media and particulate matter from syngas product. A gasification system may also include oxyblown catalytic autothermal reactor and a cryogenic air separation unit.

Abstract: A corn oil extraction process is disclosed. The process includes the recovery of corn oil and other co-products, including but not limited to steam, electric power and chemicals, from an ethanol production process and in particular, a process that involves dry corn milling methods. The process involves extraction of oil from milled corn and residues from the fermentation step, including thick stillage, distillers wet grain, distillers dry grain and distillers dry grains with solubles, by the application of an alkyl acetate, phase separation and recovery of the separated matter. A process of drying wet co-product using ethanol and carbon dioxide from the production facility is also disclosed.
