Abstract

The invention discloses a method for co-producing ethanol, acetone and butanol by using bougainvillea spectabilis vines, and belongs to the technical field of biomass energy sources. The ethanol, the acetone and the butanol are prepared from the bougainvillea spectabilis vines through the steps of drying, crushing, preprocessing, hydrolysis, fermentation. The method has the advantages that the raw material resources are wide; the ethanol, acetone and butanol co-producing cost is low; the yield of sugar prepared by the method provided by the invention is 92.21 percent to 92.91 percent; the butanol yield is 66.53 percent to 67.52 percent; the purity of the butanol is 99.61 percent to 99.73 percent, so that the sugar conversion rate and the butanol yield are improved. By using the method, the high yield of the ethanol, the acetone and the butanol can be realized. The method can be used for co-producing various novel energy sources; a novel solution is provided for the energy source lack 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 using bougainvillea 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 bougainvillea vine has low protein content but high carbohydrate content, and the carbohydrate content of individual varieties is as high as 78.89% of dry matter, so it is a high-quality raw material for biomass energy production. 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 inventio...
