摘要： The invention provides for methods for producing pulp (comprising cellulose) and lignin from lignocellulosic material, such as wood chips. The methods involve acid catalyzed hydrolysis. Lignocellulosic material having a relatively high moisture concentration can be used as the starting material. The lignocellulosic material is impregnated with an acid (preferably nitric acid) and heated. During the heating lignin is depolymerized at relatively low temperatures, and the acid catalyst is distilled off. The acid catalyst can be collected and recycled after impregnation and heating. The lignocellulosic material is then digested in an alkaline solution under heat, dissolving the lignin and allowing the pulp to be removed. Acid is added to the black liquor to precipitate the lignin which is then removed. The resultant amber liquor can be further processed into other ancillary products such as alcohols and/or unicellular proteins.
摘要翻译：本发明提供了用于从木质纤维素材料如木屑生产纸浆（包括纤维素）和木质素的方法。该方法涉及酸催化水解。可以使用具有较高水分浓度的木质纤维素材料作为原料。木质纤维素材料用酸（优选硝酸）浸渍并加热。在加热期间，木质素在较低温度下解聚，并将酸催化剂蒸馏掉。浸渍和加热后可以收集和回收酸催化剂。然后将木质纤维素材料在碱性溶液中加热消化，溶解木质素并允许除去纸浆。将酸加入到黑液中以沉淀木质素，然后将其除去。所得琥珀色液体可以进一步加工成其它辅助产物如醇和/或单细胞蛋白。

摘要： A continuous, alkaline process for the production of pulp from wood chips, wherein the preheated chips are subjected to an extended impregnation step for at least 60 min, preferably longer, at a temperature not exceeding the impregnation liquor boiling point at atmospheric conditions, and a rapid heating and cooking period of less than 65 min, preferably shorter, followed by cooling to below reaction temperature. Fresh alkali is added both during impregnation and the heating/cooking period.

摘要： Depolymerized lignins contained within black liquor are transferred to an organic solvent, soluble in organic matter and insoluble of aqueous sodium compounds contained within the black liquor. Upon separation of the aqueous sodium compounds from the organic solvent, saturated with contained depolymerized lignins, depolymerized lignins are removed from the organic solvent to result in depolymerized lignins and a separated organic solvent suitable for recycling. Resulting aqueous sodium compounds are concentrated by a multiple effect evaporator to provide liquor to digest wood chips. Whereby depolymerized lignins, substantially free from sodium compounds, are separated from a black liquor. Accordingly this invention modifies black liquor without employing a lime kiln and a recovery boiler, producing a molten smelt.

摘要： A multi-function process is described for the separation of cellulose fibers from the other constituents of lignocellulosic biomass such as found in trees, grasses, agricultural waste, and waste paper with application in the preparation of feedstocks for use in the manufacture of paper, plastics, ethanol, and other chemicals. This process minimizes waste disposal problems since it uses only steam, water, and oxygen at elevated temperature in the range of 180null C. to 240null C. for 1 to 10 minutes plus a small amount of chemical reagents to maintain pH in the range 8 to 13. An energy recuperation function is important to the economic viability of the process.

摘要： A method of treating solid containing material derived from effluent or sludge from a plant for de-inking paper, the material containing calcium in the form of one or more insoluble calcium compounds, the method including the steps of treating the material with an acid to cause dissolution of the calcium thereby forming a calcium ion-containing solution in which insoluble solids are suspended, separating the solution from the insoluble solids and incinerating the separated solids. The solution containing calcium ions may be treated by adding one or more reagents to form a calcium compound precipitate, eg calcium carbonate. The particulate solids produced following the incineration step and following the precipitate formation may be employed as pigments or fillers in paper making or paper coating.

摘要： The invention relates to a process for producing cellulose and a fertilizer by-product by using a closed cycle of cooking chemicals and process waters. In the process of the invention, the pulp is bleached by at least partly using potassium hydroxide as a bleaching chemical. Thus, a bleach concentrate rich in potassium is obtained from the bleach filtrate, which bleach concentrate is combined with ashes obtained from the burning of lignin and other organic matter recovered from pulp production as a by-product, in order to be used as a potash fertilizer. The bleach concentrate can also be used as a potash fertilizer as such. The invention also relates to a potash fertilizer obtained this way.

摘要： A novel process has been discovered whereby acid is added to the lignocellulosic material (black liquor containing lignin). The acid renders the lignin insoluble thus enabling it to be separated from the lignocellulosic material. This allows the chemical value of various components to be reclaimed. This process enables important environmental and economic benefits to be achieved. The invention obviates the need for a recovery boiler which burns the sugars and the lignin. Additionally, sodium salts are precipitated out of the process. Sodium carbonate from outside sources is used in the novel process. The supply of energy to the separation process is from a source other than the recovery furnace.

摘要： The invention relates to a process for treating bleaching liquors from pulping processes based on organic acids. The process is characterized in that inorganic acid such as nitric acid, phosphoric acid and/or sulphuric acid, is added into a bleaching liquor obtained from the bleaching or a stage closely associated with bleaching, whereby organic acids contained in the bleaching liquor are released into the bleaching liquor. The organic acids are then separated from the bleaching liquor and recycled to the cooking stage to be used as cooking chemicals. The nitrogen-, phosphor- and/or sulphur-containing product thereby produced, from which organic acids have been separated, is recovered to be used as a fertilizer or as raw material for a fertilizer.
