摘要
通过分析煤对CO2和N2的等温吸附实验结果,发现煤吸附CO2能力强于吸附N2,而煤吸附N2强于吸附O2,因此CO2的存在必定会对煤低温吸附O2过程有重要影响。考虑CO2对煤吸附氧的影响,研究了CO2对煤低温物理吸附氧过程作用实质的实验方案,试图探索延缓煤自燃的办法。
Coal can adsorb more CO2 than N2 by analyzing coal＇s isothermal adsorption experiment results, and it is found out that coal can adsorb more N2 than O2. Therefore, existence of CO2 has an impor- tant effect on oxygen physisorption process of coal at low temperature. Considering the above effect, a test plan for the oxygen physisorption process of coal at low temperature is studied to investigate a method to delay self-igniting of coal.
