Hydrogen generated from hydrocarbon streams through reformation is a major and imminent fuel source for fuel cell systems. However, the presence of sulfur limits the use of such fuels currently due the poisoning of the reformer catalyst as well as electrode assemblies. It is well-known that silver has great sulfur affinity. Adsorbents of Ag supported on SiO2 and TiO2 (Ag/SiO2 and Ag/TiO2) have shown high capacities to remove heavy sulfur compounds from logistic fuels e.g. JP-5. Heavy sulfur compounds such as methyl benzothiophenes compete for active sites dispersed on the surface of the adsorbent. The presence of aromatic compounds (16 wt or vol. %) antioxidants (20mg/l), metal deactivators (5mg/l) and icing inhibitors (0.1~0.15 Vol %) play a negative role in undermining the effectiveness of the adsorbent. Desulfurization were also conducted using a model fuel emulating the original JP5 with 16% toluene representing the aromatic content, 1000 ppmw of benzothiophene representing the sulfur content in n-hexane was used to perform adsorption studies on Ag/TiO2 adsorbent. It was observed that the adsorbent had a high capacity for aromatics along with benzothiophene. Adsorption studies were carried out using the model fuel in the absence of the aromatic content showed a three times increase in the sulfur adsorption capacity. Ag/TiO2 showed reactive behavior in decomposing the benzothiophene molecule into various hydrocarbon fractions during the adsorption cycle. This represents a process where the sulfur atom is being stripped from the benzothiophene molecule at ambient conditions. The reactive nature of the adsorbent provides better access of the active sites to the heavy sulfur compounds through the desorbing of the hydrocarbon parts of the sulfur components. The synergic combination of reactivity with high adsorptive capacity provides the present composition better performance compared to earlier adsorptive systems.
