AI Technical Summary

Problems solved by technology

In addition, lignocellulose hydrolyzate has high chemical reactivity and is prone to side reactions
Therefore, the slow reaction rate caused by the structure and the instability of the hydrolyzate lead to low conversion rate and poor selectivity of lignocellulose hydrolysis into sugar

Embodiment 1

[0022] The straw-based lignocellulose acidifier consists of the following components in parts by weight: 0.75-1.2 parts of potassium hydrogen peroxosulfate, 2.5-7.5 parts of potassium hydroxide, and 2.5-7.5 parts of sodium citrate.

Embodiment 2

[0024] The straw-based lignocellulose acidifier consists of the following components by weight: 0.65-1.1 parts of potassium hydrogen peroxosulfate, 3.5-6.5 parts of potassium hydroxide, 3.5-6.5 parts of sodium citrate, 4.1-6.9 parts of phosphoric acid, 3.9-6.1 parts of acetic acid

Embodiment 3

[0026] The acidification treatment method of straw fiber is as follows:

[0027] Add the acidulant described in Example 1 or Example 2 into the corn stalks, mix well, and let it stand in the acidification pool for 2-3 days. The weight ratio of corn stalk to acidulant is 1:3 to 1:9.

Abstract

The invention discloses a straw lignocellulose acidifying agent and an acidifying treatment method. The straw lignocellulose acidifying agent is composed of a softening agent, a lignin-reducing acidifying agent and a sugar-converting acidifying agent. After the straw resources are treated by the softener, the lignin-reducing acidifying agent and the sugar-converting acidifying agent, lignocellulose in the straw resources can be effectively degraded and converted into carbohydrates, and the content of low-molecular carbohydrates in the straw feed can be increased by the sugar-converting technology.

Description

technical field [0001] The invention belongs to the field of utilization of fiber resources, and in particular relates to a straw-based lignocellulose acidifying agent and an acidifying treatment method. Background technique [0002] Straw crops are currently a large and very important development resource, with the characteristics of large output, various types, and large availability. If the straw crops produced cannot be treated scientifically and effectively, a large amount of agricultural wastes will be formed that pollute the environment and cause a lot of waste of crops. The utilization of straw resources is the main way to reduce the pollution of agricultural wastes and the waste of resources. There are many ways to utilize straw resources, among which the use of straw resources as feed is a way with great potential at present, and the livestock and poultry waste produced through straw feed is used as organic fertilizer, which can be directly fed back to the ecologic...
