    Abstract: A method comprises introducing biomass solids to a digester comprising a reactor, a circulation system including a first injector; providing a catalyst-containing digestion medium and an organic solvent layer floating thereon; circulating the medium through the circulation system; flowing gas through the medium; keeping the medium hot enough to digest the solids; and operating the digester such a headspace exists above the solvent. The digester includes a first eductor having an inlet in the headspace, a second eductor having an inlet in the organic layer, and a downdraft tube having an inlet in the digestion medium. A motive fluid flowing from the first injector draws gas from the headspace into the first eductor, a motive fluid flowing from the first eductor draws fluid from the organic layer into the second eductor, and a motive fluid flowing from the second eductor draws fluid from the digestion medium into the downdraft tube.

    Abstract: Methods for production of ethanol, distiller's corn oil, and enhanced co-products are disclosed. Methods include obtaining a mixture of one or more co-products of an alcohol production process, which may include wet cake, performing hydrolysis of polysaccharides in the mixture to generate fermentable sugars, fermenting the fermentable sugars in the mixture to produce alcohol, distilling the mixture to remove alcohol from the mixture thereby producing alcohol-containing distillate and enhanced whole stillage, removing released oil from the fermented mixture before distillation and/or from the enhanced whole stillage after distillation, and recovering enhanced wet distiller's grains, enhanced thin stillage, and/or enhanced dried distiller's grains. Compositions disclosed herein include enhanced dried distiller's grains having a cmde protein content of at least 45% on a dry weight basis and having a total fat content of less than 10% on a dry weight basis.

    Abstract: A process for the production of benzene and ethylene from an alkane-containing gas stream. The alkane-containing gas stream may be contacted, in a reaction zone of a reactor under alkane aromatization conditions, with an aromatization catalyst including any combination of fresh, spent, and regenerated catalyst to produce an outlet stream including (i) spent catalyst and (ii) a product mixture including benzene and ethylene. The spent catalyst may be regenerated in a regeneration zone under regeneration conditions to produce the regenerated catalyst. A selected amount of fresh catalyst may be added to the regeneration zone to produce the mixture of fresh catalyst and regenerated catalyst, which may be recycled to the reaction zone. A ratio of benzene to ethylene in the product mixture may be controlled by modifying the alkane aromatization conditions, the regeneration conditions, and/or the selected amount of fresh catalyst added to the regeneration zone.
