摘要： An improved dry grind system and method for producing a sugar stream from grains or similar carbohydrate sources and/or residues, such as for biochemical production. In particular, after saccharification and prior to a sugar conversion process, a sugar/carbohydrate stream is removed from a saccharified stream. The sugar/carbohydrate stream includes a desired Dextrose Equivalent (DE) where DE describes the degree of conversion of starch to dextrose can be produced, with the such sugar stream being available for biochemical production, e.g., alcohol production, or other processes. In addition, the systems and methods also can involve the removal of certain grain components, e.g., corn kernel components, including protein and/or fiber. Sugar stream production occurs on the front end of the system and method.

The present invention further provides an acidic xylooligosaccharide having an acetyl group content of 0 to 5.0 mass %. The acidic xylooligosaccharide of the present invention, which has an acetyl group content of 0 to 5.0 mass %, can be used as a starting material in a production method to thereby obtain pentosan polysulfate with a high yield.

摘要： A process for the conversion of a solid material containing hemicellulose, cellulose and lignin, which process comprises the following steps:
(i) hydrolyzing, at a temperature equal to or less than 40° C., preferably equal to or less than 30° C., at least part of the hemicellulose of the solid material by contacting the solid material with a first aqueous hydrochloric acid solution, which first aqueous hydrochloric acid solution has a hydrochloric acid concentration in the range from equal to or more than 15.0 wt. % to less than 40.0 wt. %, based on the weight amount of water and hydrochloric acid in such first aqueous hydrochloric acid solution, yielding a remaining solid material and an aqueous first hydrolysate product solution;
(ii) displacing aqueous solution from the remaining solid material with a non-aqueous displacement fluid;
(iii) hydrolyzing, at a temperature equal to or less than 40° C., preferably equal to or less than 30° C., at least part of the cellulose of the remaining solid material by replacing the non-aqueous displacement fluid with a second aqueous hydrochloric acid solution, which second aqueous hydrochloric acid solution has a hydrochloric acid concentration in the range from equal to or more than 40.0 wt. % to equal to or less than 51.0 wt. %, based on the weight amount of water and hydrochloric acid in such second aqueous hydrochloric acid solution, yielding a residue and an aqueous second hydrolysate product solution
wherein the process is carried out in one or more reactors and wherein the reactor comprises a cylindrical vessel with its axis arranged in an essentially vertical manner, and
wherein said non-aqueous displacement fluid is a non-aqueous, preferably hydrophobic, liquid having a density equal to or less than 1000 kilograms per cubic meter (kg/m3), and
wherein the non-aqueous displacement fluid is supplied to such reactor in a downward fashion.

摘要： In one aspect, the present invention provides methods for preparing a fermentation product. The methods include pre-treating a mixture of biomass and ionic liquid, wherein the ionic liquid comprises a choline cation and the biomass comprises polysaccharide and lignin. The methods further include forming hydrolysates from the introduction of glycoside hydrolase to the pre-treated mixture at conditions sufficient to produce a sugar composition mixture for fermentation steps. The present invention provides methods for loading biomass mixtures in a batch-fed process, wherein the biomass slurries can be loaded into water or a concentrated sugar composition for hydrolysate production. The methods can be performed in a one-pot process, wherein the ionic liquids are present in the mixtures throughout each step. Aspects of the invention provide compositions of sugar composition mixtures and fermentation product mixtures.

摘要： The present invention discloses a method of preparing oligosaccharide using biomass sugar as raw material. The method places a biomass sugar in a quartz tubular reactor, places the quartz tubular reactor at a temperature-controlled zone of a tubular thermal conversion reactor under the protection of nitrogen gas, controls a thermal conversion time, rapidly quenches a material to obtain an oligosaccharide precursor after thermal conversion ends, then dissolves by adding pure water and purifies through an inorganic ultrafiltration membrane, and finally obtain an oligosaccharide after drying.
