Embodiment 1
[0038] A kind of method utilizing corn stalk to prepare butanol, comprises the following steps:
[0039] S1: The corn stalks were rinsed with 12% salt water for 2.5 hours, and after rinsing, the corn stalks were dried at a temperature of 96-104°C until the water content was ≤8%, to obtain dry corn stalks;
[0040] S2: crush the dry corn stalks prepared in step S1, and pass through a 150-mesh sieve to obtain corn stalk granules;
[0041] S3: Put the corn stalk particles prepared in step S2 into a microwave reactor, add solution A and mix evenly, heat to 62°C, pretreat at a stirring speed of 300r / min for 1.1h, then cool to room temperature and filter to prepare Obtain pretreated corn stalk particles; the solution A is a mixed solution of acetone, ethanol, ammonium phosphate, the mass concentration of the acetone is 9%, the mass concentration of the ethanol is 70%, the ammonium phosphate The mass concentration is 7%, the volume ratio of the acetone solution, ethanol solution, an...
Embodiment 2
[0045] A kind of method utilizing corn stalk to prepare butanol, comprises the following steps:
[0046] S1: Rinse the corn stalks with 10% salt water for 3 hours, and dry the corn stalks at a temperature of 96-104°C until the water content is ≤8% to obtain dry corn stalks;
[0047] S2: crush the dry corn stalks prepared in step S1, and pass through a 120-mesh sieve to obtain corn stalk granules;
[0048] S3: Put the corn stalk 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 200r / min for 1.3h, then cool to room temperature and filter to prepare Obtain pretreated corn stalk particles; the solution A is a mixed solution of acetone, ethanol, ammonium phosphate, the mass concentration of the acetone is 8%, the mass concentration of the ethanol is 60%, and the mass concentration of the ammonium phosphate is The mass concentration is 6%, the volume ratio of the acetone solution, ethanol solution, a...
Embodiment 3
[0052] A kind of method utilizing corn stalk to prepare butanol, comprises the following steps:
[0053] S1: Rinse the corn stalks with 15% salt water for 2 hours, and then dry the corn stalks at a temperature of 96-104°C until the water content is ≤8% to obtain dry corn stalks;
[0054] S2: crush the dry corn stalks prepared in step S1, and pass through a 200-mesh sieve to obtain corn stalk granules;
[0055] S3: Put the corn stalk particles prepared in step S2 into a microwave reactor, add solution A and mix evenly, heat to 64°C, pretreat at a stirring speed of 300r / min for 0.9h, then cool to room temperature and filter to prepare Obtain pretreated corn stalk particles; the solution A is a mixed solution of acetone, ethanol, ammonium phosphate, the mass concentration of the acetone is 10%, the mass concentration of the ethanol is 80%, and the mass concentration of the ammonium phosphate is The mass concentration is 8%, the volume ratio of the acetone solution, ethanol solut...
