| contents | Time dependent self-diffusion coefficient of methane molecules confined into micropores structure of a sandstone F. de J. Guevara-Rodríguez Física, Astronomía y Matemáticas diffusion Porous materials confinement effect time dependent self In this work, the effect of pore structure of a sandstone on the molecular displacement of confined methane gas is analyzed. It was found that the self-diffusion coefficient of a methane molecule depends on the pore size distribution. In particular, the time dependent self-diffusion coefficient exhibits a maximum which is correlated with the effect of the molecular confinement. It was found that a sandstone with small pores (whose diameter is less than 20A) traps the gas more efficiently than other sandstones. 2019 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57082922012 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
