Desulfurization of a JP-5 light fraction (841 ppmw S) for on-board fuel cell applications was investigated by π-complexation adsorption with mesoporous SBA-15 and MCM-41 supported Cu 2 O. The effect of support and reduction temperature on the sulfur adsorption capacity was studied. The adsorbents were characterized with N 2 physical adsorption and CO chemisorption. The results showed that the mesoporous structures of the support remained intact during adsorbent preparation. It was found that significant breakthrough occurred at 10.0 mL/g for desulfurization of the JP-5 light fraction by Cu 2 O/MCM-41 reduced at 700 °C. The MCM-41 was more effective than SBA-15 as the support for Cu 2 O adsorbents in desulfurizaiton of jet fuel. The sulfur adsorption capacity increased with the reduction temperature. The spent Cu 2 O/MCM-41 was regenerated by heating in air and the regenerated adsorbent was tested for reuse. The results showed that ∼100% of the sulfur capacity could be recovered.
