| titleOfInvention | CHEMICAL METHOD OF CELLULOSE BOILING |
| abstract | 1. A method of cooking cellulose, including: 1) cooking vegetable raw materials using composite alkali containing sulfate and lime and / or carbide slag, in order to obtain cellulose fiber containing fibers and black liquor, 2) optionally upon completion of cooking and / or the time of pulping, the addition of aluminum sulfate in order to form flakes of organic black liquor macromolecules and precipitate and adsorb them on the fibers, and then separate and / or 3) optionally add plant materials and alkali used in creatures advanced alkaline cooking technology, or other weak alkalis, such as lime and / or carbide slag, etc., into a sulfate-containing filtrate obtained by filtering off insoluble cellulose substances in order to obtain cellulose fiber. 2. A method of cooking cellulose, including: 1) cooking plant materials using existing alkaline or sulfate cooking technology to obtain cellulose fiber containing fibers and black liquor, and 2) upon completion of cooking and / or during pulping, the addition of aluminum sulfate to form flakes organic macromolecules of black liquor and their deposition and adsorption on fibers, and then separation, and / or 3) optionally the addition of plant materials, sulfate and alkali used in existing alkali technology oh pulping, or alkali composite comprising sulphate and lime and / or carbide slag, a filtrate obtained by filtering off insoluble cellulose substances to obtain cellulosic volokna.3. The method according to claim 1 or 2, wherein the alkali used in the existing alkaline cooking method is preferably |
