Embodiment 1
[0037] A method utilizing honeysuckle rattan to co-produce ethanol, acetone and butanol, comprising the following steps:
[0038]S1: Rinse honeysuckle vines with 22% salt water for 1.5-2 hours, and then dry the honeysuckle vines at a temperature of 82-104°C until the water content is 10% to obtain dried honeysuckle vines;
[0039] S2: crush the dried honeysuckle rattan obtained in step S1, and pass through a 150-mesh sieve to obtain honeysuckle rattan particles;
[0040] S3: Put the honeysuckle rattan granules 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 prepare Obtain the honeysuckle vine particle of pretreatment; Described solution A is the mixed liquor of butanone, ethanol, ammonium phosphate, and the mass concentration of described butanone is 9%, and the mass concentration of described ethanol is 70%, and the mass concentration of de...

[0044] A method utilizing honeysuckle rattan to co-produce ethanol, acetone and butanol, comprising the following steps:
[0045] S1: The honeysuckle vines were rinsed with 18% salt water for 2 hours, and after rinsing, the honeysuckle vines were dried at a temperature of 82-104°C until the water content was 9%, to obtain dried honeysuckle vines;
[0046] S2: crush the dried honeysuckle rattan obtained in step S1, and pass through a 120-mesh sieve to obtain honeysuckle rattan particles;
[0047] S3: Put the honeysuckle rattan granules 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 prepare Obtain the honeysuckle vine particle of pretreatment; Described solution A is the mixed solution of butanone, ethanol, ammonium phosphate, and the mass concentration of described butanone is 8%, and the mass concentration of described ethanol is 60%, and t...
Embodiment 3
[0051] A method utilizing honeysuckle rattan to co-produce ethanol, acetone and butanol, comprising the following steps:
[0052] S1: The honeysuckle vines were rinsed with 25% salt water for 1.5 hours, and after rinsing, the honeysuckle vines were dried at a temperature of 82-104°C until the water content was 10%, to obtain dried honeysuckle vines;
[0053] S2: crush the dried honeysuckle rattan obtained in step S1, and pass through a 180-mesh sieve to obtain honeysuckle rattan particles;
