Medium low alkali biochemical catalyst

Abstract

The invention relates to a medium and low alkali biochemical catalyst which is composed of inorganic alkaline, lipase, anthraquinone, osmotic agent and surface active agent, wherein, the mass percentage of all the components is as follows: inorganic alkaline 35 percent to 45 percent, lipase 10 percent to 15 percent, anthraquinone 15 percent to 20 percent, osmotic agent 10 percent to 15 percent and surface active agent 10 percent to 15 percent. The catalyst is applicable in the dipping and fiber processing of cornstock, cotton stalk, willow timber, reed, Anaphalis yedoensis, straw, pernyi and other plant fiber under normal temperature and normal pressure. The sources of the raw materials are wide and the scope of application is wide. The catalyst can improve the speed of delignify and the fiber yield, and reduce the residual alkali value.

Description

technical field [0001] The invention belongs to the field of catalysts, in particular to a medium-low alkali type biochemical catalyst. Background technique [0002] In recent decades, some scientific research institutes and enterprises at home and abroad have researched and developed the pollution-free fiber extraction technology, and the process routes are roughly as follows: [0003] (1) Blasting method: also known as thermal spraying method. The method is to put rice and wheat straw into a high-temperature and high-pressure container. When a certain temperature and pressure are reached, the pressure is released instantly to form a blast, and the plant straw is separated into fine fibers. [0004] (2) Dry method: the plant straw is broken into filaments, and the screened filaments are evenly distributed on the Fourdrinier by air flow, and then glued and hot-pressed. Adding glue consumes a lot of non-renewable resources such as inorganic glue and organic glue; the fiber ...

AI Technical Summary

Problems solved by technology

Adding glue consumes a lot of non-renewable resources such as inorganic glue and organic glue; the fiber is brittle and not durable

[0005] For decades, the above technology is still in the laboratory stage and has not achieved large-scale production

[0006] (3) The traditional pulping technology is to put plant straws such as sawdust, rice, wheat straw, etc. into the steaming ball, mix chemical raw materials, cook under high pressure and high temperature, and then complex reactions of lignin and miscellaneous cells in plants with alkali ( It will greatly reduce the strength, effective length and output rate of the fibrils, and at the same time, it will mutate to form a black liquor with complex components, which seriously exceeds the COD, BOD, AOD indicators), and then wash it away with a large amount of water to obtain a single fiber

Due to the degree of digestion and absorption and financial reasons, the operation results are not very satisfactory and need to be further improved
