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;
[0046] S2: crush the dry creeper prepared in step S1, and pass through a 120-mesh sieve to obtain creeper granules;
[0047] S3: Put the creeper particles prepared in step S2 into a microwave reactor, add solution A and mix evenly, heat to 56°C, pretreat at a stirring speed of 100r / min for 1.8h, 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 8%, the mass concentration of the ethanol is 60%, and the phosphotungstic The mass concentration of acid ammonium salt is 6%, the volume ratio of described methyl ethyl ke...
Embodiment 3
[0051] A kind of method utilizing creeper to co-produce ethanol, acetone and butanol, comprises the following steps:
[0052] S1: The creeper was rinsed with 25% salt water for 1.5 hours, and after rinsing, the creeper was dried at a temperature of 85-103°C until the water content was 10%, to obtain a dry creeper;
[0053] S2: crush the dry creeper prepared in step S1, and pass through a 180-mesh sieve to obtain creeper granules;
[0054] S3: Put the creeper particles prepared in step S2 into a microwave reactor, add solution A and mix evenly, heat to 66°C, pretreat at a stirring speed of 400r / min for 0.6h, then cool to room temperature and filter to obtain Pretreated creeper particles; the solution A is a mixture of butanone, ethanol, ammonium phosphotungstate, the mass concentration of the butanone is 10%, the mass concentration of the ethanol is 80%, and the phosphotungstic The mass concentration of acid ammonium salt is 8%, and the volume ratio of described butanone solut...
