不同煤階軟硬煤的吸附—解吸規(guī)律及應(yīng)用
[Abstract]:Based on a large number of domestic and foreign research results, the problems in the study of adsorption and desorption of soft and hard coals with different rank are analyzed, and pore structure parameters, macromolecular structure parameters, adsorption constants of soft and hard coals with different metamorphism are tested. The pore structure and macromolecular structure of soft and hard coals with different rank were studied by desorption data. The adsorption potential well of different broken types of coal was calculated by quantum chemical MP2 method, and the mechanism of methane adsorption by coal was explained microscopically. The adsorption characteristics of soft and hard coal with different rank were studied and its control mechanism was found. A comprehensive model of methane adsorption by coal was established by using adsorption potential theory, and an experimental system of high efficiency gas adsorption and desorption of high quality coal samples with temperature control function was set up. The desorption law and control mechanism of soft and hard coal with different rank were studied. The critical value of gas content in outburst area of coal with different metamorphism was determined and the reliability of calculating method of gas content loss was analyzed.
