The possibility of using fuel cells as the power source for highly fuel efficient transportation vehicles has gained substantial attention recently. The fuel cell technology favored by most vehicle manufacturers is proton exchanged membrane (PEM) fuel cells operating with H2 from hydrocarbon steam reforming or partial oxidation. The successful development of fuel-cell powered vehicle is depending on the developement of fuel processor. As part of the development of gasoline fuel processor system for intergration with PEM fuel cell, we investigated POX reforming reaction of iso-Octane with/without 100ppm sulfur and reformulated naphta with less than 5 ppm sulfur over a commercial naphta reforming catalyst. We also investigated high temperature water gas shift (HTS) reaction over Fe3O4-Cr2O3 catalysts and low temperature shift (LTS) reaction over Cu/ZnO/Al2O3 catalyst to remove CO from the hydrogen-rich stream produced by fuel processing section. It was found that the commercial reforming catalyst waspron to be poisoned by sulfur contained in i-octane, but there is no coke deposition at 700 oC under tested condition. We confirmed that the concentration of CO in hydrogen-rich stream is reduced less than 3000 ppm after reformated gas from gasoline over naphta reforming catalyst was passed through HTS and LTS reactors. In order to reduce the concentration of CO in hydrogen-rich stream and compact the size of fuel processor, a preferential partial oxidation (PROX) reactor and new high-performance catalysts with sulfur- and coke-resitance will be needed. |
