摘要： The present invention is a method for producing pulp from fibrous lignocellulose material using a treatment step which exposes the material to oxalic acid, or oxalic acid and sodium bisulfite, prior to pulping. The pulping of the resulting product requires less energy input and provides a pulp having enhanced physical properties as compared to untreated materials.

摘要： In a new process for preparing pulped wood chips for paper making, chips from a hardwood such as eucalyptus are inoculated with aliving culture of one or more white rot fungi. The fungi propagate throughout the body of the wood chip, selectively attacking the lignin of the wood without harming the cellulosic fibers. Subsequent mechanical pulpting results in reduced utilization of energy, improved strength, and reduced cooking time.

摘要： A method using biological processes in the production of pulp from industrial wood waste is described. The process makes use of various species of white-rot fungi which selectively degrade lignin. The industrial wood waste must be cleaned and hydrated prior to inoculation with the fungus. Paper produced by this process has excellent strength characteristics as compared to both non-treated industrial wood waste and pulp produced from virgin wood chips. Substantial energy savings are also realized when the biopulped industrial wood waste chips are further refined by conventional mechanical pulping procedures. Kraft pulping of wood waste resulted in strength properties comparable to those of virgin wood. Fungal pretreatment subsequently enhanced the resulting kraft pulp properties.
摘要翻译：描述了使用生产工艺在工业木材废料生产纸浆中的方法。该方法利用选择性降解木质素的各种白腐真菌。在用真菌接种之前，必须对工业废木材进行清洁和水化。与未经处理的工业木屑和由原始木片生产的纸浆相比，通过该方法生产的纸具有优异的强度特性。当通过常规的机械制浆方法进一步精制生物泵的工业废木屑时，也可实现显着的节能。木材废料的牛皮纸制浆导致与原始木材相当的强度性能。真菌预处理随后提高了所得牛皮纸浆的性质。

摘要： The present invention provides a method for producing an MDF board from pulp from a fibrous lignocellulose material using a treatment or pretreatment step which exposes the material to oxalic acid or oxalic acid derivatives (particularly dialkyl ester derivatives, particularly in the vapor phase). The treated wood is then subjected to a sugar extraction wash and refined using any one of the several pulping methods to produce a final pulp product. Once this is done the pulp is used to make MDF boards having improved water repellency properties.

摘要： The present invention is a method for producing a pulp from a fibrous lignocellulose material or source using a treatment or pretreatment step which exposes the material to oxalic acid derivatives, particularly dialkyl ester derivatives, particularly in the vapor phase. Once treated, the material may be refined using any one of the several pulping methods to produce a final pulp product and the production of the product is accompanied by strength increases in paper made from the pulp and energy savings in making the pulp, hi addition the treatment or pretreatment produces a soluble carbohydrate source and other components (e.g. acetic acid, other wood components) for further product development. In certain cases a pulp product is not produced and all of the carbohydrate present in the lignocellulose is converted into soluble sugars.

摘要： A method of using biological processes as a pretreatment step in combined biological and mechanical paper pulping process is described. The process uses a species of fungus, Ceriporiopsis subvermispora, which has not previously been used for this purpose. It has been found that even with a non-optimized system, and with the stationary holding of the wood chips during fungal incubation, that significant savings in energy usage in the pulping process can be achieved compared to conventional mechanical pulping while simultaneously achieving increased strength characteristics in the paper.
