摘要： A digestion method for producing pulp which comprises digesting a lignocellulose material by using an alkaline digesting liquor containing polysulfides in the presence of a quinone-hydroquinone compound having a value obtained by reducing an oxidation-reduction potential observed in a form being present during digestion to a standard oxidation-reduction potential (Ea), wherein an activity of hydrogen ion is 1, in the range of 0.12 to 0.25 V to the standard hydrogen electrode potential. The method can be used for digesting a lignocellulose material to a pulp having a low kappa value in high yield, and also for reducing the amount of chemicals to be used and for reducing a load on a boiler for recovery.

摘要： The invention relates to a process for producing pulp from cellulosic fiber material with improved polysulfide regeneration alone or in combination with polysulfide cooking. The cellulosic fiber material is impregnated with polysulfide before cooking followed by extraction of spent cooking liquor. A portion of the spent cooking liquor is gasified to hydrogen sulphide and treated to form an acidic gas comprising hydrogen sulphide and carbon dioxide. The acidic gas is reacted under conditions providing a hot stream of elemental sulphur, said stream admixed with an alkaline liquor containing sulphide. An alkaline polysulfide liquor is thus formed which is added during cooking or impregnation. During cooking is a portion of the extracted spent cooking liquor recycled to the impregnation step and a desired polysulfide concentration in the impregnation step is maintained by adding polysulfide liquor.

摘要： A method for Kraft pulping employing a modified cooking process in conjunction with polysulfide pulping technologies to obtain higher pulping yields than obtained in the prior art. The total required alkali charge (polysulfide liquor) is added to the beginning of a cook, and after all polysulfide has essentially reacted with lignocellulosic material at temperature below that at which no significant carbohydrate degradation occurs, a first quantity of the cooking liquor high in effective alkali (EA) concentration is removed from a first point in the pulping process and replaced with a cooking liquor low in EA concentration removed from another process point. The first quantity is then added elsewhere in the pulping process, where the EA concentration is low. This cooking liquor "exchange" obtains the full yield benefit from polysulfide pulping and a more uniform EA concentration profile to retain the major benefits of modified cooking.
