    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 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.
