Embodiment 1

[0037] A kind of method utilizing creeper to co-produce ethanol, acetone and butanol, comprises the following steps:

[0038]S1: Rinse the creeper with 22% salt water for 1.5-2 hours, after rinsing, dry the creeper at a temperature of 85-103°C until the water content is 10%, to obtain a dry creeper;

[0039] S2: crush the dry creeper prepared in step S1, and pass through a 150-mesh sieve to obtain creeper granules;

[0040] S3: Put the creeper particles prepared in step S2 into a microwave reactor, add solution A and mix evenly, heat to 60°C, pretreat at a stirring speed of 300r / min for 1.2h, then cool to room temperature and filter to obtain Pretreated creeper particles; the solution A is a mixed solution of butanone, ethanol, ammonium phosphotungstate, the mass concentration of the butanone is 9%, the mass concentration of the ethanol is 70%, and the phosphotungstic The mass concentration of acid ammonium salt is 7%, the volume ratio of described methyl ethyl ketone solutio...

Embodiment 2

[0044] A kind of method utilizing creeper to co-produce ethanol, acetone and butanol, comprises the following steps:

[0045] S1: The creeper was rinsed with 18% salt water for 2 hours, and after rinsing, the creeper was dried at a temperature of 85-103°C until the water content was 9%, to obtain a dry creeper;

Abstract

The invention discloses a method for co-producing ethyl alcohol, acetone and butanol through boston ivies and belongs to the technical field of biomass energy. The ethyl alcohol, the acetone and the butanol are prepared through the steps of boston ivy drying, smashing, pretreatment, hydrolysis, fermentation and the like. The source of the raw material is wide, and the cost of co-producing of the ethyl alcohol, the acetone and the butanol is low. The sugar yield is 92.26%-92.97%, the butanol yield is 66.58%-67.61%, the butanol purity is 99.59%-99.69%, it states that the sugar conversion rate and the butanol yield are high, and by means of the method, the ethyl alcohol, the acetone and the butanol can be produced in a high yield mode. By means of the method, multiple 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 ivy. 【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 creeper is low but the carbohydrate content is high, and the carbohydrate content of individual species is as high as 79.1% 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. At present, the yields of butanol and ethanol are still relatively low. The bottleneck is that ...
