“…The process, combining steam reforming (SR) and catalytic partial oxidation (POX) reactions, to achieve an overall net heat balance, can be considered free from the disadvantages of the other methods, like slow start-up, considerable heat input or output, higher catalyst loadings, larger reactors and mass transfer limitations [1,2]. Besides, temperature, pressure, O 2 /fuel and H 2 O/fuel ratios, can be selected as independent parameters to optimize the performance of the ATR process in terms of H 2 yield, to avoid coke deposition on catalyst or to minimize the by-products formation [3,4].…”

− PEM fuel cell vehicles have been getting much attraction due to a sort of highly clean and effective transportation. The onboard fuel processor, however, is inevitably required to supply the hydrogen by conversion from some fuels since there are not enough available hydrogen stations nearby. A lot of studies have been focused on analyses of ATR reactor under the assumption of thermo-neutral condition and those of the optimized process for the minimization of energy consumption using thermal efficiency as an objective function, which doesn't guarantee the maximum hydrogen production. In this study, the analysis of optimization for 100 kW PEMFC onboard fuel processor was conducted targeting various fuels such as gasoline, LPG, diesel using newly defined hydrogen efficiency and keeping simply synthesized heat exchanger network regardless of external utilities leading to compactness and integration. Optimal result of gasoline case shows 9.43% reduction compared to previous study, which shows the newly defined objective function leads to better performance than thermal efficiency in terms of hydrogen production. The sensitivity analysis was also done for hydrogen efficiency, heat recovery of each heat exchanger, and the cost of each fuel. Finally, LPG was estimated as the most economical fuel in Korean market.

Hydrogen has been attracting great interest as a major energy source in near future. The lack of an infrastructure has led to a research effort to develop fuel processing technology for production of hydrogen. In this review, we are reporting the catalytic reforming of gaseous hydrocarbons carried out in our research group, covering dry-reforming of CH 4 , tri-reforming of CH 4 , the electrocatalytic reforming of CH 4 by CO 2 in the SOFC (solid oxide fuel cell) system and steam reforming of LPG. Especially, we have focused on our work, though the related work from other researchers is also discussed wherever necessary. It was found that tri-reforming of CH 4 over NiO-YSZ-CeO 2 catalyst was more desirable than dry-reforming of CH 4 due to higher reforming activity and less carbon formation. The synthesis gas produced by trireforming of CH 4 can be used for the production of dimethyl ether, Fischer-Tropsch synthesis fuels and high valued chemicals. To improve the problem of deactivation of catalyst due to carbon formation in the dry reforming of CH 4, the internal reforming of CH 4 by CO 2 in SOFC system with NiO-YSZ-CeO 2 anode catalyst was suggested for cogeneration of a syngas and electricity. It was found that Rh-spc-Ni/MgAl catalyst showed long term stability for 1,100 h in the steam reforming of LPG under the tested conditions. The addition of Rh to spc-Ni/MgAl catalyst restricted the deactivation of catalyst due to carbon formation in the steam reforming of LPG and diesel under the tested conditions. The result suggested that the developed reforming catalysts can be used in the reforming process of CH 4 , LNG and LPG for application to hydrogen station and fuel processor system.
