Abstract

The invention discloses a method for utilizing rosa banksiae to co-produce ethyl alcohol, acetone and butanol and belongs to the technical field of biomass energy. The ethyl alcohol, the acetone and the butanol are prepared through the steps of rosa banksiae drying, smashing, pretreatment, hydrolysis, fermentation and the like. The raw material is wide in source, and the cost for co-producing the ethyl alcohol, the acetone and the butanol is low. The glucose conversion rate of the butanol prepared by means of the method is 92.22%-92.93%, the yield of the butanol is 66.54%-67.57%, the purity of the butanol is 99.59%-99.71%, it is shown that the glucose conversion rate and the yield of the butanol are high, and the high-yield ethyl alcohol, acetone and butanol can be achieved by means of the method. By the adoption of the method, a variety of new energy resources can be co-produced, and a new solution is provided for the energy shortage problem.

Description

【Technical field】 [0001] The invention belongs to the technical field of biomass energy, and in particular relates to a method for co-producing ethanol, acetone and butanol by using woody 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 widespread attention, and the production of fuel butanol and ethanol from crop wastes is considered to be the most promising industry. The protein content of Muxiangteng is low but the carbohydrate content is high, and the carbohydrate content of individual species is as high as 78.89% of the dry matter, so it is a high-quality raw material for the production of biomass energy. Domestic and foreign studies on the conversion of vines to fuel butanol and ethanol have started, but the yields of butanol and ethanol are still relatively low. Therefore, the in...
