Removal of Sulfur Compounds from Natural Gas by Adsorption on Ag-Exchanged Zeolites for PEFC

摘要

The newly-developed desulfurization materials based on Ag-zeolites performed the high sulfur adsorption capacities from a pipeline natural gas at ambient temperature in the presence of moisture. The sulfur adsorption capacity of Ag(Na)-Y was higher than those of the other adsorbents and was not to be easily influenced by water content in the natural gas. Clear color change was observed by the adsorption experiment on Ag(Na)-Y.
