Abstract
The present invention relates to a pulping catalytic cracking agent without steaming and boiling. The pulping catalytic cracking agent comprises at least one kind of active biological enzyme, a kind of anthraquinone compound, at least one kind of penetrating agent, EDTA sodium salt or sodium dithionite, an oxidative bleaching agent and alkali. When used, the catalytic cracking agent is proportionally added into water, fibrous raw materials are soaked in the solution f under the conditions of the room temperature or a temperature between 30 and 55 DEG C and the atmospheric pressure or 2 to 6 hours, and the reaction is finished. Because the reaction temperature is low, the separated soak liquid is yellowy and can be repeatedly used after being filtered. In addition, the present invention has the advantages of great reduction of energy consumption, high pulp yield, low production cost, low soaked liquid colloid content and easy filtration.
Description
Technical field
The present invention relates to pulp technology for making paper, particularly a kind of catalytic pyrolyzing agent for pulping without steaming and boiling that is used for pulp production.
Background technology
Papermaking technology is invented by Chinese, history in several thousand has been arranged so far, the key link of papermaking is slurrying, traditional pulp-making method need carry out boiling with fibrous plants under high-temperature and high-pressure conditions, need add a large amount of alkali during boiling, cooking process slurrying produces a large amount of black liquor, and black liquid is the pollution sources of intractable.
Solvent pulping is external technology newly developed, mainly be with the slurrying of alcohol organic solvent method, the temperature of general reaction is all more than 100 ℃, the time of reaction all needs several hrs, biology enzyme slurrying also obtains certain achievement, but also there are a lot of difficult problems in these technology, can't realize that suitability for industrialized production (sees " pulping and paper-making cleaner production new technology " ISBN7-5025-4716-9/X.323 of Chemical Industry Press for details, Pg5-33; Pg67-73).
Chinese patent discloses the method for preparing paper pulp under two kinds of normal temperature, the condition of normal pressure; " medicine catalytic reaction string is made the method for paper pulp under the normal temperature and pressure " (application number: 200310105602.5); " clean pulping catalyst and technique for applying thereof " (application number: 200310115531.7).The method of catalysis has all been adopted in these two patent applications, because the reaction condition gentleness does not produce black liquor, but above-mentioned two technology all are batch process production from technology analysis, and its catalyst or medicament are not open, analyze from its prescription, do not contain biologic product yet.
Summary of the invention
The purpose of this invention is to provide a kind of catalytic pyrolyzing agent for pulping without steaming and boiling, use the present invention and can realize that normal temperature or low temperature (30～55 ℃) uses fibrous raw material slurrying, pulping process does not produce black liquor, the recyclable utilization of soup.
The present invention realizes by following scheme: comprises at least a active biological enzyme and a kind of anthraquinone compounds in its composition of a kind of catalytic pyrolyzing agent for pulping without steaming and boiling, also comprises at least a bleeding agent, EDTA sodium salt or sodium dithionite, and oxidative bleaching agent and alkali;
Above-mentioned active biological enzyme is cellulase or hemicellulase;
Above-mentioned active biological enzyme is an alkali protease;
Above-mentioned bleeding agent is a triethanolamine;
Above-mentioned anthraquinone compounds is a kind of of hydroxy-anthraquione, amino anthraquinones or tetrahydro-anthraquinone;
Above-mentioned oxidative bleaching agent is hydrogen peroxide or clorox;
Above-mentioned active biological enzyme is cellulase or hemicellulase;
Above-mentioned alkali is sodium hydroxide solution;
The optimum weight proportioning of each composition of the present invention is: clorox 5～10%, triethanolamine 2～10%, cellulase 10～22%, hydroxy-anthraquione 0.04～0.08%, EDTA sodium salt 0.03～0.08%, sodium dithionite 0.03～0.08%, all the other are NaOH.
The present invention in making up water by a certain percentage, soaked fibrous raw material 2 to 6 hours under normal temperature or 30～55 ℃ of condition of normal pressure when using, just finish reaction, because reaction temperature is low, isolated soak color is yellowish, can reuse after the filtration, in addition, cut down the consumption of energy greatly, pulping rate is higher, and production cost is lower, liquid glue body burden after the immersion is few, easily filters.
