Influence of Hydrogen Sulfide on Adsorption Storage of Methane by Activated Carbon
摘要
Abstract
Methane adsorption capacity was determined for activated carbon as an adsorbent material made from macadamia nut shells. The limiting amount adsorbed is 13 mmol g–1 (22 wt %) at a pressure of 40 MPa and 303 K. The influence of hydrogen sulfide on methane adsorption capacity has been established. At a concentration of 1%, after 5 charging–discharging cycles, the ability to adsorb methane gas is little affected. However, this parameter was reduced by up to 15.4% after performing 10 charging and discharging cycles; reduced by 38.5% after 20 cycles and 61.5% after 30 cycles.
