Abstract

Desulfurization of natural gas using the adsorption method for fuel cells has been investigated. Sulfur capacities of activated carbon (AC), Fe/AC, BEA zeolite (BEA), and Fe/BEA were obtained from the breakthrough curves of tert-butyl mercaptan (TBM) and tetrahydrothiophene (THT). Temperature programmed desorption (TPD) of TBM and THT was conducted on the adsorbents also. The sulfur-adsorption capacities appear to be closely related to the desorption area of chemisorbed sulfur compounds. Fe/BEA (Fe: 3%) prepared by the ion-exchange method exhibits the highest sulfur capacity (19.6% gs -comp/g sorb) among the adsorbents tested because of the strong chemisorption of sulfur compounds on the Lewis acid sites present in BEA zeolite and the beneficial Fe effect on the Fe/BEA adsorbent through the possibility of complexation.
