Embodiment 1

[0035] A kind of method utilizing kiwi fruit vine to prepare ethanol, comprises the following steps:

[0036] S1: Rinse the kiwifruit vines with 12% salt water for 2.5 hours, and then dry the kiwifruit vines at a temperature of 98-104°C until the water content is ≤9% to obtain dried kiwifruit vines;

[0037] S2: crush the dried kiwifruit vines prepared in step S1, and pass through a 150-mesh sieve to obtain kiwifruit vine particles;

[0038] S3: Put the kiwifruit vine granules prepared in step S2 into a microwave reactor, add solution A and mix evenly, heat to 66°C, pretreat at a stirring speed of 200r / min for 0.7h, then cool to room temperature and filter to prepare Obtain pretreated kiwifruit rattan particles; the solution A is a mixed solution of butanone, ethanol, ammonium phosphate, the mass concentration of the butanone is 9%, the mass concentration of the ethanol is 70%, and the ammonium phosphate The mass concentration of salt is 7%, and the volume ratio of described ...

Embodiment 2

[0042] A kind of method utilizing kiwi fruit vine to prepare ethanol, comprises the following steps:

[0043] S1: Rinse the kiwifruit vines with 10% salt water for 3 hours, and then dry the kiwifruit vines at a temperature of 98-104°C until the water content is ≤9% to obtain dried kiwifruit vines;

[0044] S2: crush the dried kiwifruit vines prepared in step S1, and pass through a 120-mesh sieve to obtain kiwifruit vine particles;

[0045] S3: Put the kiwifruit vine granules prepared in step S2 into a microwave reactor, add solution A and mix evenly, heat to 64°C, pretreat at a stirring speed of 200r / min for 0.8h, then cool to room temperature and filter to prepare Obtain the kiwifruit rattan 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 the mass concentration of described ammonium phosphate The ma...

Embodiment 3

[0049] A kind of method utilizing kiwi fruit vine to prepare ethanol, comprises the following steps:

[0050] S1: Rinse the kiwifruit vines with 15% salt water for 2 hours, and after rinsing, dry the kiwifruit vines at a temperature of 98-104°C until the water content is ≤9% to obtain dried kiwifruit vines;

[0051] S2: crush the dried kiwifruit vines prepared in step S1, and pass through a 200-mesh sieve to obtain kiwifruit vine particles;

Abstract

The invention discloses a method for preparing ethyl alcohol from Chinese gooseberry stems, and belongs to the technical field of biomass energy. The ethyl alcohol is prepared from the Chinese gooseberry stems through the steps of drying, pulverization, pretreatment, hydrolysis, fermentation and the like. The uncertainty of a microbial enzyme fermentation sugar making process can be avoided, and the technical risk is lowered. The glucose conversion rate is high; the generated residue quantity is small; the method belongs to a green and environmentally-friendly process. The preparation process is simple; the investment is low; the method is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the technical field of biomass energy, and in particular relates to a method for preparing ethanol from kiwifruit 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 increasing attention, and the production of fuel ethanol from crop wastes is considered to be the most promising industry. The planting area of ​​kiwi fruit in our country is very wide, and a large amount of kiwi fruit vines are also produced every year when the fruit is harvested. The protein content of kiwifruit vine is low but the carbohydrate content is high, and the carbohydrate content of individual varieties is as high as 82% of the dry matter, so it is a high-quality raw material for the production of biomass energy. Research on the conversion of vines to fuel ethanol has s...
