Abstract

The invention belongs to the field of biomass energy, and relates to a preparation method for tape grass biomass fermentation liquid glucose. In the preparation method provided by the invention, tape grass is hydrolyzed, and the specific process comprises the steps of tape grass cleaning and smashing, metal salt catalytic hydrolysis and the like. The preparation method for the tape grass biomass fermentation liquid glucose, provided by the invention has the advantages as follows: (1), the source of raw materials is wide, and the tape grass as float grass naturally growing at river bottom occupies no agricultural acreage, so that the production cost of the tape grass biomass fermentation liquid glucose is low; (2), the preparation technology is simple, and the dependence on instruments, equipment and places is low, so that the tape grass biomass fermentation liquid glucose is suitable for large-scale popularization and application; (3), environmental protection is realized, waste water, waste residues and waste gas which are harmful to the environment are hardly generated in the production process, and the microbial fermentation is not needed. Therefore, the tape grass biomass fermentation liquid glucose prepared by the invention can be used as raw material for producing alcohol, and has wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of biomass energy, and in particular relates to a method for preparing sugar liquid fermented with bitter grass biomass. Background technique [0002] The use of biomass materials to produce ethanol is of great significance to alleviate the energy crisis and environmental degradation (Biomass Chemical Engineering, 2012, 46(3), 39-44). Biomass materials are mainly composed of cellulose, hemicellulose and lignin, among which cellulose and hemicellulose are the main sources of fermentable sugars. Due to the complexity of lignocellulosic material composition, the tightness of connections, and the rigid structure of lignification, it has brought many difficulties to the thorough hydrolysis of cellulose and hemicellulose, so the hydrolysis of lignocellulosic materials into fermentable sugars has low efficiency and high efficiency. Cost is the bottleneck in the commercial production process of bioethanol. Pretrea...
