Methods are described for converting carbohydrates including, e.g., monosaccharides, disaccharides, and polysaccharides in ionic liquids to value-added chemicals including furans, useful as chemical intermediates and/or feedstocks. Fructose is converted to 5-hydroxylmethylfurfural (HMF) in the presence of metal halide and acid catalysts. Glucose is effectively converted to HMF in the presence of chromium chloride catalysts. Yields of up to about 70% are achieved with low levels of impurities such as levulinic acid.

A process for the treatment of biomass to render structural carbohydrates more accessible and/or digestible using concentrated ammonium hydroxide with or without anhydrous ammonia addition, is described. The process preferably uses steam to strip ammonia from the biomass for recycling. The process yields of monosaccharides from the structural carbohydrates are good, particularly as measured by the enzymatic hydrolysis of the structural carbohydrates. The monosaccharides are used as animal feeds and energy sources for ethanol production.

High-yielding method for chemical hydrolysis of lignocellulose into monosaccharides. The process of the invention can additionally be applied to cellulose, xylan and related biomass polysaccharides, such as galactan, mannan, or arabinan. The method is employed for hydrolysis of a biomass polysaccharide substrate. The process is carried out in an ionic liquid in which cellulose is soluble in the presence of catalytic acid at a temperature sufficiently high to initiate hydrolysis. Water is added to the reaction mixture after initiation of hydrolysis at a rate controlled to avoid precipitation yet avoid undesired sugar dehydration products such ad HMF. Hydrolysis product is useful as feedstock for fermentations including fermentation processes for ethanol, butanol and other fuels.

The invention discloses a method for preparing fuel ethanol from bamboo fibers. The method comprises the following steps that: waste from bamboo (or other non-wood biomass) processing is used as a raw material, the raw material is cut, dried, crushed and passed through a 80-mesh sieve, the powder passing through the 80-mesh sieve is fine bamboo powder and the powder failing to pass through the 80-mesh sieve is coarse bamboo powder; the coarse bamboo powder is cooked in a mixed liquid of formic acid, acetic acid and water for hydrolyzing hemicellulose and delignification, and fibers are obtained and subjected to hydrolysis by an organic acid to form a reducing monosaccharide; the fine bamboo powder is hydrolyzed directly by the organic acid to form the reducing monosaccharide; the reducing monosaccharide obtained from the hydrolysis of the hemicelluloses, the fibers and the fine bamboo powder are detoxicated by an excess amount of Ca(OH)2, the pH of the mixture is reduced, and the fuel ethanol is obtained after fermentation and rectification. The method for producing the fuel ethanol ensures the yield of the fuel ethanol, reduces the energy consumption for hydrolysis, and allows the organic acid used for hydrolysis to be recycled. In addition, the process of the fuel ethanol preparation using the method requires less water, and reduces environmental pollution and cost.

This invention relates to a process for producing a lactose-free milk which does not confer a sweet taste to the milk normally resulting from the hydrolysis of lactose into monosaccharides. The process comprises the step of reducing the lactose content of the milk to about 3% prior to hydrolysis with lactase. When the milk is skimmed milk, the protein content may be increased to about 3.8-4.0% or greater, which further improves the organoleptic properties of the milk. Milk so processed and dairy products derived therefrom are also disclosed and claimed.
