Temperature-Programmed Oxidation Experiments on Typical Bituminous Coal Under Inert Conditions

Abstract: In this study, an experimental investigation was presented on the oxidation behaviors of bituminous coal for different inert gases (N2 and CO2) at different concentrations (oxygen concentration indexes 21%, 18.4%, 15.8%, and 13.1%) using a temperature-programmed experimental device. The purpose of this research was to examine the oxidation patterns of bituminous coal under different inert conditions. The results showed that (1) the oxidative heating of the coal underwent two stages: an initial slow heating sta… Show more

“…Ambient conditions have important influences on the explosive characteristics of combustible gas. Therein, the ambient pressure and ambient temperature exert the greatest influences. In China, high-temperature condition is inevitable in coal mines with the increase in mining depth and spontaneous ignition of coal seams. , In the utilization of low-concentration oxygen-containing gas, processes including methane extraction by pressure swing adsorption, gas deoxygenation and concentration, and low-concentration gas regenerative oxidation also encounter high-temperature conditions, so the temperature rise poses a severe challenge for controlling gas explosion. Therefore, studying explosive characteristics of methane under high-temperature conditions can provide an important theoretical basis for the prevention of gas explosion accidents, design of bearing pressure devices, and explosion venting design.…”
