Charge/Discharge Characteristics Of High-capacity Methane Adsorption Storage Systems

Impacts of Gas Impurities from Pipeline Natural Gas on Methane Storage in Metal–Organic Frameworks during Long-Term Cycling

“…Biloe et al used expanded natural graphite (ENG) as an adsorbent and reported that the thermal conductivity in the system was about 30 times higher than that of activated carbon packed bed, which provides a more isothermal operating condition. Mota and Blazek et al introduced reversible phase-change materials into an adsorbent bed to transfer the heat generated from the adsorption cycle to desorption cycle. Here we focus on ANG tank for vehicular use and assume a flow rate low enough in both filling and release operations , that allows us to assume isothermal conditions in the adsorption and desorption processes.…”

“…The undesirable exothermic behavior of adsorption processes reduces the adsorption capacity (BILOÉ; GOETZ; GUILLOT, 2002) hence heat exchange systems have been developed, such as U-tubes (BASUMATARY et al, 2005;RAHMAN et al, 2011;YANG, X. D. et al, 2005) and phase change materials (PCM) (BLAZEK et al, 1990;LI;LI, 2015;RACKLEY, 2010;SAKANAKA et al, 2020) inserted in packed bed adsorption systems. The latter offers great potential because they are capable of storing substantial amounts of energy.…”
