Abstract: Furfural is produced from biomass material containing pentosan, in high yields, in a production process comprising treating the biomass with a solution containing at least one α-hydroxysulfonic acid thereby hydrolyzing the biomass to produce a product stream containing at least one C5-carbohydrate compound in monomeric and/or oligomeric form, and dehydrating the C5-carbohydrate compound in the presence of a heterogeneous solid acid catalyst, in a biphasic reaction medium comprising an aqueous phase and a water-immiscible organic phase, at a temperature in the range of from about 100° C. to about 250° C. to produce a dehydration product stream containing furfural. An aqueous stream is separated from the dehydration product, which can be optionally recycled to the hydrolysis step.

CPC classification number: C12P7/10
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 crude 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.
