Abstract

The invention relates to the field of carbon dioxide cracking in coal mine, in particular to a heating material for a carbon dioxide cracker. The heating material is prepared from following raw materials in parts by weight: 45-55 parts of Chinese locust charcoal powder, 10-14 parts of calcium peroxide, 7-9 parts of sodium bismuthate, 13-19 parts of peat and 12-16 parts of activated clay. The invention further discloses a preparation method of the heating material for the carbon dioxide cracker. The preparation method comprises following steps: 1), the Chinese locust charcoal powder, the activated clay, calcium peroxide, sodium bismuthate and the peat are weighed in a formula ratio and poured into a beaker in sequence; 2), the materials in the beaker are slowly stirred to be uniform by a glass bar; 3), the materials obtained after sufficient mixing are put in a storage bag. Liquid carbon dioxide can be converted into gaseous carbon dioxide, so that a coal bed is subjected to technical treatment of cracking, penetration enhancement and desorption by carbon dioxide, and purposes of safe and fast extraction and outburst elimination are achieved.

Description

technical field [0001] The invention relates to the field of carbon dioxide cracking in coal mines, in particular to a heating material for a carbon dioxide cracker and a preparation method thereof. Background technique [0002] The heat source is an important component of the carbon dioxide cracker, which quickly converts liquid carbon dioxide into gaseous carbon dioxide. Using the coal-friendly characteristics of carbon dioxide to coal seam, which has a higher adsorption capacity than gas, the coal seam is treated with cracking and anti-permeability desorption technology, and a large amount of adsorbed gas is covered by carbon dioxide. The dissociated gas is turned into free gas, so that the gas permeability and gas freeness of the coal seam are double improved, and the goal of safe and fast drainage and outburst elimination is achieved. [0003] The chemicals in the heat source of the existing carbon dioxide cracker have a slow heating rate and a small heat generation, wh...
