Experimental Analysis on Effects of Cycling Operation of Methane Adsorption and Desorption on Monolithic Activated Carbon

چکیده مقاله

Using pressure vessels filled with activated carbon to store and transport of natural gas as one the important resources of energy at moderate pressures up to 800 psia and ambient temperature has been studied as a potential alternative to compressed natural gas (CNG) at high pressures (about 3000 psia). The present studies provide an experimental investigation of adsorption and desorption cycles of natural gas in a prototype storage vessel filled with monolithic activated carbon and analysis the effect of the gas cycling on the adsorption and desorption capacity. Many studies are devoted to the characterization of suitable adsorbent materials to optimize the methane storage capacity. Nevertheless, since the natural composition include about 95% of methane mixed with other components, an important deterioration of the storage performance is observed after successive cycles of an ANG system. In the present study, the changes of the methane capacity of a 10 cycling operation is experimentally measured.
