    摘要: The disclosure is concerned with a pretreatment process for removing lignin from lignocellulosic material so as to enhance enzymatic or microbial decomposability of cellulose. The pretreatment process comprises wetting lignocellulosic material with an alkaline aqueous solution in a manner that interstices between the cellulosic material remain, and exposing the wetted cellulosic material to an ozone-containing gas so as to decompose lignin in the lignocellulosic material with a very small energy consumption.

    摘要: Wood and/or woody wastes, particularly coniferous woods, are treated to render them suitable as a high energy food for ruminating animals. Comminuted wood or woody wastes are impregnated with a glycol or glycol-ether solvent and a catalyst, and the mixture heated to a temperature of at least 145.degree. C. for a time sufficient to delignify the wood the desired amount and solubilize extraneous components in the wood which are detrimental to the digestibility of the treated wood by the ruminant. The treated wood is then defibrated and the glycol solvent and catalyst extracted from the treated wood and recovered for recycle and reuse. The pulp recovered from extraction is a substantially anhydrous pulp which can be injected with nutrients promoting greater digestibility of the pulp and rehydrated for feeding to the ruminant.

    摘要: A process for treating plant organic matter particles to increase the digestability thereof by ruminants including mixing the organic particles with water, a nontoxic acid catalyst to produce a Ph lower than 3.0, and a metallic catalyst of either iron or manganese, oxidizing the mixture under elevated pressure and temperature to fragment the cellulose molecules and break the lignin-cellulose bond, and hydrolizing the oxidized mixture under elevated pressure and temperature to convert at least a portion of the cellulose molecules to saccharides and saccharide acids.
