    摘要： A method of treating cellulose-containing materials to increase chemical and biological reactivity of cellulose. The cellulose is contacted, in a pressure vessel, with a volatile liquid swelling agent having a vapor pressure greater than atmospheric at ambient temperatures, such as ammonia. The contact is maintained for a sufficient time to enable said agent to swell the cellulose fibers. The pressure is rapidly reduced to atmospheric, allowing said agent to boil and explode the cellulose fiber structure. The rapid pressure reduction also causes some freezing of the cellulose. The agent is separated from said cellulose and recovered for recycling.

    摘要： A nontoxic cellulose solvent and process for forming and utilizing the same. The solvent includes a metal chelating agent, a metal compound, an oxygen scavenging stabilizing agent and a caustic swelling agent with the disclosed solvent being prepared in either aqueous or solid form. The solvent is caused to contact cellulosic materials in order to dissolve cellulose therefrom. The dissolved cellulose may be reprecipitated and may then be hydrolyzed by cellulose enzyme or acid to yield glucose with lignin being removed either before or after hydrolysis has occurred.

    摘要： 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.

    摘要： A process for producing a microbial growth stimulant (MGS) from a plant biomass is described. An ammonium hydroxide solution is used to extract a solution of proteins and ammonia from the biomass. Some of the proteins and ammonia are separated from the extracted solution to provide the MGS solution. The removed ammonia can be recycled and the proteins are useful as animal feeds.

    摘要： This process for increasing the reactivity of cellulose-containing materials such as animal feedstuffs involves contacting the material, in a pressure vessel, with a volatile liquid swelling agent e.g. ammonia, which has a vapor pressure greater than atmospheric pressure at ambient temperatures. The contact is maintained for a time period sufficient for the agent to swell the cellulose of the material. The pressure is then rapidly reduced to atmospheric pressure, thereby causing the agent to boil and explode the material. The rapid pressure reduction also causes some freezing of the cellulose. The swelling agent is separated from said cellulose-containing material and recovered for recycling. The process also increases the water holding capacity of cellulose-containing materials.

    摘要： A method for treating biomass is provided, which includes, in a reactor, allowing gaseous ammonia to condense on the biomass and react with water present in the biomass to produce pretreated biomass, wherein reactivity of polysaccharides in the biomass is increased during subsequent biological conversion as compared to polysaccharides in biomass which has not been pretreated. A method for treating biomass with a liquid ammonia and recovering the liquid ammonia is also provided. Related systems which include a biochemical or biofuel production facility are disclosed.
