Patent ID: 8658321

Claim:
A sulfur adsorbent system for use in removing sulfur from a hydrocarbon used in a fuel cell processing train, the sulfur adsorbent system comprising a zeolite Y adsorbent ion exchanged with a cation selected from the group consisting of Cu, Ag, Mn, Mg, Fe, Ca, Ce, La, Sr, Pr, Nd, and mixtures thereof and a selective sulfur adsorbent, wherein the sulfur adsorbent system is configured such that the hydrocarbon sequentially passes through both the zeolite Y adsorbent and then the selective sulfur adsorbent placed together in the sulfur adsorbent system at a temperature below 100° C. and wherein the desulfurization within that sulfur adsorbent system is performed substantially not by chemical desulfurization processes.
