Gas adsorption has been studied in recent years as an alternative to store gases which may be used as fuels, such as methane and hydrogen. It has been shown that textural and surface properties, such as the pore size and/or adsorbent-adsorbate interaction, are important in the adsorption capacity of these gases in porous materials [1,2]. In this work is presented a comparative study of different porous materials which may be used as an alternative to store methane by an adsorption process. There were selected, among those commercially available, a set of the most recognized microporous materials, namely: zeolites, activated carbons, and metal organic frameworks (MOF). These samples were exhaustively characterized by nitrogen adsorption-desorption and studied in methane adsorption at high pressure conditions and different temperatures.
