| Abstract: | The research of coal methane adsorption and desorption at home and abroad mainly stay research on the adsorption and desorption mechanism and on the adsorption and desorption reversibility test stage.From the perspective of micro-elements,it is introduced that MC(Monte Carlo) simulation method for molecular adsorption of methane,the principle of analytic modeling and main steps of the simulation(for ensemble selection;the establishment of an analytical model adsorption;initial conditions and periodic boundary treatment;start simulation;random processes of simulation;calculate the thermodynamic average of ensemble;simulation result authentication in laboratory).The problems to be solved are discussed which MC simulation method has been applied to molecular adsorption and desorption of methane,in order to prove that MC simulation method is feasible. |
