Abstract

The invention discloses a method for preparing butyl alcohol by using green soy bean straws, and belongs to the technical field of biomass energy. The butyl alcohol is prepared by the steps of drying, crushing, pretreating, hydrolyzing and fermenting the green soy bean straws. The method disclosed by the invention is wide in raw material source and low in cost of preparing butyl alcohol, has a high glucose conversion rate, and generates a small amount of residues, so that the method is a green and environment-friendly process. Compared with fuel prepared by a petroleum refining method, the biofuel, namely butyl alcohol, prepared by the method disclosed by the invention has a significant environmental protection effect and can effectively reduce the emission of room temperature gases. Meanwhile, the method also provides a new solution for solving the problem of shortage of energy.

Description

【Technical field】 [0001] The invention belongs to the technical field of biomass energy, and in particular relates to a method for preparing butanol from edamame stalks. 【Background technique】 [0002] Due to the popularization of coal, electricity and natural gas and the abundance of various industrial products in China in the past two decades, the demand for edamame stalks in rural areas has decreased. The disposal of a large amount of edamame stalks has become a serious social problem. Burning edamame stalks will cause air pollution, fires, and the failure of planes to take off and land normally. [0003] 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 butanol from crop wastes is considered to be the most promising industry. Edamame is planted in a wide area in my country,...
