application of lattice boltzman method in modeling of methane adsorption breakthrough curve

A d2q9 lattice boltzmann model was developed to solve the unsteady state concentration profile of methane adsorption from nitrogen in a packed bed of activated carbon# this method solved the time-dependent convection-diffusion-reaction equation for methane adsorption in a bed of activated carbon# the programming matlab code was written for simulating methane mass transfer zone inside the bed with axial dispersion and using adsorption rate as a sink term in the boltzmann equation# the present study provided an alternative numerical approach to solve adsorption mass transfer problems# validation of the lbm numerical breakthrough curve was carried out by experimental data and the results have shown good agreement with outlet concentration of methane from the bed versus time# this research has demonstrated the ability of the lbm model for numerical modeling dynamic adsorption systems#
