Problems solved by technology

Although there are various types of impregnated carbons on the market, such as NH3 impregnated carbons, H2S, SO2 impregnated carbons, NOx protective materials, HCN, CHCL protective materials, etc., but in terms of protection objects, these impregnated carbons are currently Carbon can only meet the protection of a certain kind or a certain type of toxic and harmful substances. When it is too late to figure out the types of toxic and harmful gases and the types of toxic and harmful gases are complicated, the above impregnated carbon cannot meet the protection requirements.

Abstract

The invention belongs to the technical field of impregnated carbon, and particularly relates to efficient impregnated carbon capable of effectively purifying multiple industrial toxic and harmful gases in a complex environment. The efficient impregnated carbon adopts broken coconut shell activated carbon as carrier framework material, and the carrier framework material is loaded with 13wt%-20wt% of Cu, 2wt%-6wt% of Mo, 0.1wt%-3wt% of Zn, 0-7wt% of CO3<2-> and 5wt%-10wt% of SO4<2->. The impregnated carbon provided by the invention is high in generality, good in universality and wide in protection spectrum, can meet the purification demand and the protection demand of the complex environment, is capable of effectively purifying gases in time especially under the condition that the types of the toxic and harmful gases can not be figured out in time and the varieties of the toxic and harmful gases are complicated, and is in accordance with the demand of market development.

Description

technical field [0001] The invention belongs to the technical field of impregnated carbon, and provides a method for preparing high-efficiency impregnated carbon that can be used in complex environments to effectively purify various industrial toxic and harmful gases. Background technique [0002] Activated carbon and its impregnated carbon are the core poison filter materials of chemical defense equipment (including individual combat protective equipment and cluster protective equipment) that were gradually developed and widely used after the two world wars. With the development of chemical warfare, the research on military poisons in various countries is increasing and deepening, and the development of impregnated carbon is also changing with each passing day, from the initial activated carbon, single-component loading (A-type activated carbon catalyst) to multi-component loading ( AS type, ASC type, ASC-T type and ASZM-T type activated carbon catalyst, etc.), from the ini...
