Abstract
In order to study the effect of H2S on gas adsorption in coal seam, the adsorption characteristics of single-component CO2, CH4, N2 and H2S and multi-component H2S mixed with CO2, CH4 and N2 by anthracite were simulated by using the Grand Canonical Ensemble Monte Carlo (GCMC) method. The results show that the adsorption capacity of CO2, CH4, N2 and H2S in anthracite decreases with the increasing of temperature and increases with the increasing of pressure. The adsorption isotherms of CO2, CH4, N2, H2S and different ratios of H2S/CH4, H2S/N2, H2S/CO2 were consistent with the Langmuir equation. The adsorption capacity of H2S and CO2 is significantly higher than that of N2 and CH4. There is competitive adsorption among H2S, CO2, CH4 and N2, and the adsorption capacity of H2S is better than that of CO2, CH4 and N2.
