摘要： The invention is related to a method for the preparation of kraft pulp with increased pulping yield from lignin-containing cellulosic material using polysulfide cooking liquor. In order to obtain a cost efficient system both in aspects of investment costs but also in aspects of heat economy of operating the process is most of the total charge of alkali charged as heated polysulfide liquor to an first atmospheric vessel, wherein the hot polysulfide liquor flashes off steam providing most if not all of the necessary steaming effect for the cellulose material. The polysulfide liquor is then allowed to impregnate the cellulose material at a temperature closer to cooking temperature but still so low that essentially no delignification occurs in impregnation vessel, as the H-factor in impregnation vessel is kept within 1-20.

摘要： The present invention relates to a process for preparing lactic acid and/or a lactate salt via the fermentation of carbohydrates obtained from lignocellulosic material. In particular the process comprises: a) treating a lignocellulosic material with an alkaline agent comprising a caustic magnesium salt in the presence of water to provide a treated aqueous lignocellulosic material; b) saccharifying the treated aqueous lignocellulosic material in the presence of a hydrolytic enzyme to provide a saccharified aqueous lignocellulosic material comprising fermentable carbohydrates and a solid lignocellulosic fraction; c) fermenting the fermentable carbohydrates in the saccharified aqueous lignocellulosic material by means of lactic acid producing microorganism in the presence of an alkaline agent comprising a caustic magnesium salt to provide an aqueous fermentation broth comprising a magnesium lactate; and d) isolating lactic acid and/or lactate salt from the fermentation broth; wherein the saccharification step b) and the fermentation step c) are performed as two separate steps.

摘要： The present disclosure relates to methods for detoxifying a hydrolysate obtained from a lignocellulosic biomass and methods of producing ethanol from the detoxified hydrolysate. The present methods provide detoxified hydrolysates in which the quantity of compounds that are deleterious to fermenting microorganisms are substantially reduced relative to the starting hydrolysate and in which the amount of fermentable sugars loss is minimal.

摘要： The invention concerns a method, system and a withdrawal screen section for the impregnation of chips during the manufacture of chemical pulp. Chips are both steamed and impregnated in a low pressure impregnation vessel 3, using pressurised hot spent cooking liquor BL as the main part of the impregnation liquid, which hot spent cooking liquor produce most of the steam BLSτ necessary for steaming the chips. In order to improve the process in the impregnation vessel 3 are at least two independent first and second screen rows, SC1 and SC1 b respectively, installed. The first screen row withdraws acidified treatment liquor for disposal which otherwise would be a parasitic acidified waste fluid in the system, and the second screen row recirculates treatment fluid back to centre of treatment vessel in order to even out the pH profile over the cross section of the vessel.

摘要： Impregnating or spraying softwood chips in a solution containing an appropriate concentration of alkaline earth metal ions selected from the group consisting of calcium ions, barium ions and strontium, preferably calcium ions, at room temperature before a reductive alkaline pulping process, for example kraft pulping, significantly increases pulp yield. Using an agent that complexes with the metal ions, such as hydroxyethylidene diphosphonic acid (HEDP) allows this benefit of metal ions to be achieved during the pulping process rather than in a separate impregnation step.
