PROCESS OF INDUSTRIAL CELLULOSE PULP, NATIVE LIGNIN AND UNICELLULAR PROTEIN PRODUCTION, WHICH IS CARRIED OUT IN CATALYTIC REACTOR Russian patent published in 2010 - IPC D21C3/16 D21C3/26 D21C11/10 D21C9/18 D21C1/00 

FIELD: textiles, paper.

SUBSTANCE: invention is related to pulp and paper industry. Method for processing of lignocellulose material includes stage of impregnation, at which lignocellulose material is soaked in impregnation solution; the first stage of recycle, at which impregnation solution is drained, filtered, concentrated and returned to the stage of impregnation; stage of catalytic reaction, at which soaked lignocellulose material is mixed on chamber of catalytic reaction and heated up to the temperature over point of impregnation solution evaporation, thus, evaporated impregnation solution and lignin are produced. Besides method includes the second stage of recycle, at which evaporated impregnation solution is condensed and returned to stage of saturation; stage of boiling, at which lignin is energetically mixed in cooking boiler in presence of black iron and alkaline solution for production of cellulose pulp and black lye of full concentration; stage of processing, at which cellulose pulp is drained, washed and dried, thus, dried cellulose pulp and dissolved black lye are produced. Method includes the third stage of recycle, at which dissolved black lye is returned to the stage of boiling; stage of separation, at which black lye of full concentration is cooled and energetically mixed in presence of acid solution, thus, sweet lye is produced, as well as deposited lignin of natural origin; stage of filtering, at which sweet lye is filtered in order to extract lignin of natural origin, and stage of fermentation, at which sweet lye is added to bacteria in fermentation apparatus, thus, unicellular protein is produced as product of fermentation. Invention is related to device for processing of lignocellulose material, and also unicellular protein and lignin, which are produced by above-mentioned method.

EFFECT: possibility is provided to process various types of vegetable material with no necessity in re-equipping or variation of technological equipment, prevention of environmental pollution and reduction of power inputs.
