Abstract

The present invention provides a method for processing plant raw materials; in the present invention, the raw materials are pulverized, extracted with hot water, sieved to remove impurities, and then added with a specific proportion of n-butanol or isobutanol, oxidants and other additives, The cooking reaction, through the mutual cooperation of pretreatment conditions, solvent addition amount, oxidant addition amount, other additive addition amount and cooking conditions, synergizes, facilitates the penetration of reagents, fully separates raw material components, and basically retains active groups , remarkably improve the cooking efficiency and product yield, so that the product performance is better, the invention has a simple process, can realize industrialized large-scale production, can bring good economic benefits to enterprises, and has broad prospects.

Description

technical field [0001] The invention belongs to the field of lignocellulosic raw material processing, and relates to a method for processing plant raw materials. Background technique [0002] The traditional fossil energy is depleting day by day, but the demand for it is increasing year by year. Therefore, the development and research of petroleum substitutes is imminent. Lignocellulosic raw materials are the most abundant organic matter in nature, and the conversion and utilization of lignocellulosic raw materials has become an inevitable trend. The main components of lignocellulosic raw materials are cellulose, hemicellulose and lignin. After effective separation, the three major components can be converted into high value-added bioenergy, materials and chemicals through processing. [0003] Existing lignocellulosic treatment technologies include physical methods, physical-chemical methods, chemical methods, biological methods, etc., which have poor separation effects an...
