Monte Carlo simulation of natural gas adsorption storage in pillared layered material

Grand canonical ensemble Monte Carlo (GCEMC) method has been used for adsor ption storage of methane, the main component in natural gas, in pillared la yered material at T = 300K, Pillared layered material is modeled by the app roach of Yi et al. with the uniform distribution of pillars. Methane is des cribed as a spherical Lennard - Jones molecule, and 10 - 4 - 3 potential fr om Steele is used for representing the interaction between methane and a ca rbon wall in the GCEMC simulation. The local density profiles and the adsor ption isotherms of methane adsorbed in pillared layered material with 4 var ious porosities in the pores of width 1. 36 nm were obtained. Consequently, an optimum porosity of the pillared layered material is recommended for th e adsorption storage of methane.
