| 초록 | Catalytic partial oxidation (POX) of hydrocarbons for generating hydrogen has gained much attraction in recent years owing to its direct application in proton exchanged membrane (PEM) fuel cells for generating clean electrical energy. The successful development of fuel-cell powered vehicle is depending on the development of fuel processor. Hydrogen is the ideal fuel for a PEM fuel cell because it simplifies the system integration [1]. However, a direct hydrogen system has many disadvantages such as the lack of widespread refueling infrastructure and high storage volume compared to the hydrocarbon based fuels [2-3]. A reformer based vehicle system has the advantage of using the existing hydrocarbon fuels that are more readily available. There is growing interest in the development of gasoline reformers, as this would allow fuel-cell vehicles to fit into the existing fuel infrastructure instantly [4-5]. Considering the favorable factors required for the on-board generation of H2 in a fuel cell vehicle, POX reforming (or autothermal reforming, ATR) attracts much attention primarily because of a low energy requirement [6]. As a part of development of a gasoline fuel processor system for integration with PEM fuel cell, we have carried out the POX reforming of iso-octane over the commercial reforming catalyst obtained from Haldor Topsoe (HT). Various aspects of the POX reforming of gasoline for fuel-cell powered applications has already been reported by the authors [7-8]. iso-Octane is the principal component in gasoline and, therefore, the results obtained over the iso-octane feed can be extended to study a gasoline fuel processor system. Especially, the effects of reaction temperature, oxygen/carbon (O/C) molar ratio and water/carbon (H2O/C) molar ratio were investigated to minimize deactivation of the catalyst caused by coke deposition. Since the key issue to be addressed in a commercial reforming system is the sulfur tolerance of the reforming catalysts, we have investigated the extent of sulfur tolerance of the HT catalyst using a standard iso-octane feed containing 100 ppm of S. |
