Abstract

The invention discloses an environment-friendly separation process for valuable components in biomass materials. The environment-friendly separation process comprises the following steps of crushing the biomass materials; adding water for pulverizing-leaching treatment on the crushed biomass materials; activating the pulverized and leached materials in a stirring device; conveying the activated materials to a reaction kettle for pyrohydrolysis, wherein the temperature is controlled to 150-220 DEG C and the pressure is controlled to 0.5-3MPa during pyrohydrolysis; filtering a reaction product after pyrohydrolysis, wherein filter liquor mainly comprises hydrolysis components of hemicellulose in the biomass materials, filter residue can be subsequently treated, a lignin degradation component, cellulose and other components can be further separated through subsequent oxydative degradation. The method has the advantages of convenient operation, low equipment investment, low-price and easily obtained materials, environment friendliness, circular using of biomass resource and the like.

Description

technical field [0001] The invention relates to a treatment method based on biomass, in particular to a method for selectively separating valuable components from biomass raw materials. Background technique [0002] At present, acid, alkali chemicals and organic solvents are commonly used in domestic biomass treatment for selective separation. Although those skilled in the art have been exploring advanced biomass raw material pretreatment methods, the current overall treatment cost is still high Still, production costs remain uncompetitive with conventional commodity fuels and chemicals. In order to meet the requirements of industrial production and commercial application, the pretreatment process of biomass raw materials still needs to be improved. [0003] Suresh Chandra Srivastava and others disclosed a single-step method for separating biomass components in CN101680165A Chinese patent document (application number 200880014753.0), which uses immiscible A mixture of orga...
