Abstract

The invention belongs to the technical field of gas absorbent materials, and in particular relates to a gas absorbent and its preparation method and application. Including the following raw materials in parts by weight: 30-70 parts of pseudo-boehmite; 35-55 parts of water glass; 130-150 parts of aluminum sulfate aqueous solution; 100-120 parts of sodium hydroxide aqueous solution; 2-5 parts of methane-oxidizing bacteria liquid . The gas absorbent can quickly remove the gas in the environment, reduce the gas concentration, avoid the use of toxic and harmful components, and reduce the personal injury to the miners through the proportioning of each component and the addition of the methane oxidizing bacteria solution.

Description

technical field [0001] The invention belongs to the technical field of gas absorbent materials, and in particular relates to a gas absorbent and its preparation method and application. Background technique [0002] The definition of gas is quite broad, not a single substance. Including domestic natural gas and coal mine gas. Gas is formed by the decomposition of cellulose and organic matter by anaerobic bacteria in the initial stage of coal accumulation by ancient plants. In the environment of high temperature and high pressure, while coal is formed, gas continues to be generated due to physical and chemical effects. Gas is a colorless, tasteless, and odorless gas, but sometimes you can smell an apple-like aroma, which is due to the simultaneous release of aromatic hydrocarbon gas and gas. The relative density of gas to air is 0.554. Under standard conditions, the density of gas is 0.716kg. The permeability of gas is 1.6 times that of air. Suffocate due to lack of oxygen...
