Abstract

The invention discloses a method of preparing ethanol from muskmelon vine, and belongs to the technical field of biomass energy. The ethanol is obtained through the following steps: drying muskmelon vines, grinding, and carrying out pretreatment, hydrolysis, and fermentation. The uncertainty of microbial enzymatic fermentation sugar production technology can be avoided, the technological risk is reduced, the sugar conversion rate is high, the generated residue amount is little, the technology is green and environment-friendly; the hydrolysis temperature is lower, the energy consumption is less, and thus the technology is easy to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of biomass energy, and in particular relates to a method for preparing ethanol from muskmelon vines. Background technique [0002] With the growth of population, food, energy and environment are the most important challenges facing human beings. The production of renewable clean energy from cellulosic raw materials has attracted increasing attention, and the production of fuel ethanol from crop wastes is considered to be the most promising industry. Cantaloupe has a wide planting area in my country, and a large amount of cantaloupe vines are also produced every year when the fruit is harvested. Cantaloupe vine has low protein content but high carbohydrate content, and the carbohydrate content of individual varieties is as high as 81% of dry matter, so it is a high-quality raw material for biomass energy production. Research on the conversion of vines to fuel ethanol has started at home and abroad, but comp...
