Abstract

The present invention relates to a kind of method that utilizes bamboo to make paper pulp, relate to firstly splitting bamboo vertically and transversely and then going through the process of screening and washing to reduce the consumption of medicines in the process of prehydrolysis and pulping and make it easy to react, thereby A method of making pulp from bamboo and its pulp that can produce better-quality, higher-yield dissolving pulp, and that can prevent the generation of dioxins by using the bleaching method of ECF or TCF. Since the anthraquinone caustic soda method using anthraquinone as a catalyst is used in the cooking process, the effects of improving delignification and pulp quality and increasing pulp yield are obtained. Also, the content and degree of polymerization of Ξ±-cellulose can be arbitrarily adjusted according to the characteristics of the man-made fibers produced as desired by adjusting the conditions of prehydrolysis, cooking and bleaching. At the same time, by recovering xylose produced in the dissolving pulp manufacturing process, it is used to manufacture xylitol, seasoning, furfural, etc., thereby contributing to the improvement of resource utilization and economic efficiency of waste.

Description

technical field

[0001] The present invention relates to a method of utilizing bamboo to produce dissolving pulp, in particular to a method of utilizing bamboo to produce cellulose (dissolving) pulp and the pulp thereof. Hemicellulose is bleached by bleaching agent with less environmental pollution, so as to produce high-quality dissolving pulp with high yield of pulp production and no emission of environmental pollutants such as dioxin. Background technique

[0002] Paper and dissolving pulp are generally considered to be produced from wood. Here, the dissolving pulp refers to cellulose pulp, and refers to pulp that can be made into fibers from the cellulose pulp in the future. That is, in the past, wood pulp accounted for the vast majority, but recently due to insufficient wood resources, it has become a major issue to protect forests and maintain the environment to produce pulp as a raw material for papermaking. try.

[0003] Such non-wood plants...
