Gas clusters can reprove the sewage ability of flame-permeability char joint, but the interaction motion between proposed vapor molecules and gasoline-confine charcoal during the wind enema advance is still unclear. For this consideration, supported by the surface assimilation figure of qualifier-enclose char, the magnificent orthodox whole Monte Carlo (GCMC) manner was interesting to ponder the elution conduct of CH4 in the wind-confine charcoal configuration after the farding bag of N-2/CO2 under distinct enema stamp. The clockwork of N-2/C advances the elution of CH4 in charcoal. The examination ensues showed the following: (1) Compared with the enema of N-2, the gasoline-restrain charcoal has more familiar CH4 molecules after CO2 enema, and the constituting force of the CH4-CO2 system is everywhere more humble than that of the CH4-N-2 system, the former is more fix. (2) In the same enema pattern, obtained with the CH4-N-2 system, the CH4 grout indicated more regular distribution in the CH4-CO2 system. CH4 heptane is more active, the expansion cooperation of CH4 in the CH4-CO2 system is more, and the effect of CO2 in promoting the elution of CH4 is better. (3) After CO2/N-2 is interjected into the fart-hold charcoal construction, as the enema compression extension, the referring concentrations of CO2, N-2, and CH4 in the coping wax, the opposite to major of CH4 in the CH4-CO2 system is the zenith everywhere. In the CH4-N-2 system, the opposite to major of CO2 in the CH4 and CH4-CO2 system is in the centric, and the opposite to major of N-2 in the CH4-N-2 system is the lowermost. (4) The reasonably enema affliction for N-2 to raise CH4 elution is between 2 and 4 MPa, and CO2 is honest to advance CH4 elution. The enema urgency is between 3 and 4 MPa. Based on this data, methane extraction and resource utilization can be improved to a certain extent. The result has shown that the inquiry effect can condition speculative uphold for the research studies of char cicatrix petrol enema irritation technology.
