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.

Production of ethanol and enhanced co-products using co-products as feedstock

An acid-generating fluid includes a thermally activated strong acid precursor. The thermally activated strong acid precursor can include a component selected from aldehydes, ketones, and combinations thereof, in combination with a precursor of a compound adapted to react to liberate sulfur dioxide; or it can include sulfur dioxide in combination with a precursor of a compound adapted to react to liberate a component selected from aldehydes, ketones, and combinations thereof.

Thermally activated strong acids

Fermentable sugar useful for the production of biofuels can be produced from biomass by contacting the biomass with a solution containing at least one &#x3b1;-hydroxysulfonic acid. The &#x3b1;-hydroxysulfonic acid can be easily removed from the product and recycled.

A weighted acid composition comprising an acid, a brine, and an amino acid and associated methods.

Weighted acid compositions comprising amino acids

Inducibly degradable compositions comprising polyacetal and associated methods and systems.

Inducibly degradable polyacetal compositions for use in subterranean formations

An acid-generating fluid comprising a thermally activated strong acid precursor is provided in the method of the present invention. The thermally activated strong acid precursor comprises sulfur dioxide or a first precursor of a compound adapted to react to liberate sulfur dioxide, and an aldehyde and/or a ketone or a second precursor of a compound adapted to react to liberate an aldehyde and/or ketone. The acid-generating fluid is placed into a subterranean formation, where the first precursor and/or the second precursor are thermally activated, thereby liberating sulfur dioxide and the aldehyde and/or ketone. The sulfur dioxide and the aldehyde and/or ketone are reacted to form a thermally activated strong acid.

A novel method of separating bio oil (pyrolysis oil) into oxygenated rich species and lignin/phenolic based species in a highly efficient manner is provided. Lignin and phenolic fractions can be separated from light oxygenates from bio oil by use of reversible &#x3b1;-hydroxysulfonic acid.

Method of separating lignin derived compounds from pyrolysis oil

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 &#x3b1;-hydroxysulfonic acid thereby hydrolyzing the biomass to produce a product stream containing at least one C-carbohydrate compound in monomeric and/or oligomeric form, and dehydrating the C-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&#xb0; C. to about 250&#xb0; 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.

Process for preparing furfural from biomass

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 &#x3b1;-hydroxysulfonic acid thereby hydrolyzing the biomass to produce a product stream containing at least one C-carbohydrate compound in monomeric and/or oligomeric form, and dehydrating the C5-carbohydrate compound in the presence of an acid, 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&#xb0; C. to about 250&#xb0; C. to produce a dehydration product stream containing furfural. An aqueous stream is separated from the dehydration product that can be optionally recycled to the hydrolysis step.

Since biomass is always accompanied by caustic inorganic materials, we have found that the formation of the anion salt of &#x3b1;-hydroxysulfonic acid represent the largest 'loss' of the &#x3b1;-hydroxysulfonic acid in the potential reversible acid pretreatment process. By titrating the &#x3b1;-hydroxysulfonic acid salt with strong mineral acid and then reverting the alfa-hydroxysulfonic acid as its primary components, the acid components can be recovered substantially quantitatively.

Process for treating biomass to produce materials useful for biofuels

Embodiments of the present invention provide for efficient and economical production and recovery of ethanol or other volatile organic compounds. One embodiment comprises contacting a solid component of a biomass material with a solution adapted to facilitate saccharification. The solid component is generated by a method comprising: introducing a biomass material to a compartment of a solventless recovery system, wherein the biomass material contains one or more volatile organic compounds; contacting the biomass material with a superheated vapor stream in the compartment to vaporize at least a portion of an initial liquid content in the biomass material; separating a vapor component and a solid component from the heated biomass material; and retaining at least a portion of the gas component for use as part of the superheated vapor stream. In one embodiment, the solid component contacted with the solution is further subjected to enzymatic hydrolysis and/or fermentation.

Methods and systems for processing biomass material

A method of treating ethanol production byproduct is provided by treating wet distillers grain or stillage with a solution containing at least one &#x3b1;-hydroxysulfonic acid to produce at least one fermentable sugar containing product. Fermentable sugar useful for the production of biofuels or ethanol can be produced from such methods. The &#x3b1;-hydroxysulfonic acid can be easily removed from the product and recycled.

Method of treating ethanol production byproducts

Fermentable sugar useful for the production of biofuels is produced from biomass in a continuous or semi-continuous manner by providing pumpable biomass.
