Abstract

The invention relates to an active carbon material, and particularly relates to a method for preparing food hygiene-level active carbon by use of biological waste resource bagasse. The method comprises the steps of collecting and cleaning the residual bagasse after sugar production; sufficiently fermenting at 10-50 DEG C, drying, grinding and sieving; then performing the operation treatment such as soaking in an active agent solution, charring, activation and the like on the pretreated bagasse; washing, drying and grinding to obtain a high-performance active carbon product which can be applied to decoloration, refining and impurity removal of the sugar industry and the fields of foods and medicines such as medicinal crude drugs and the like. According to the method provided by the invention, by adopting the waste bagasse as a raw material, the comprehensive utilization of resources and environmental protection are facilitated; moreover, the price is low, the product quality is high, and the economic and social benefits are good.

Description

technical field

[0001] The invention relates to an activated carbon material, in particular to a method for preparing food hygiene-grade activated carbon by utilizing the biological waste resource-bagasse. Background technique

[0002] Bagasse is the main by-product of the sugar industry and an important renewable biomass resource; China is the third largest sugarcane planting country after Brazil and India, with a total sugarcane output of more than 70 million tons. The fibrous stalk material-bagasse has an output of more than 7 million tons; the composition of bagasse is mainly cellulose, hemicellulose and lignin, and the content of protein, starch and soluble sugar is less; due to the lignification of bagasse The degree is relatively high, and there are silicified cells in the stem epidermis. It has been difficult to be effectively transformed and utilized for a long time, and it is often discarded, or simply used as fuel, and the utilization rate is very low. The pollut...
