“…These features make hydrogen an excellent fuel to potentially meet the increasingly stringent targets for exhaust emissions from combustion devices, including the reduction of greenhouse gas emissions. Hydrogen can be used in internal combustion engines (ICE) on its own or as a partial substitute for traditional ICE fuels to improve performance and emissions, as has been reported by many researchers [2][3][4][5][6][7][8][9][10][11].…”

Abstract:The performance of Ni-Cu/Al 2 O 3 catalysts for steam reforming (SR) of gasoline to produce a hydrogen-rich gas mixture applied in a spark ignition (SI) engine was investigated at relatively low temperature. The structural and morphological features and catalysis activity were observed by X-ray diffractometry (XRD), scanning electron microscopy (SEM), and temperature programmed reduction (TPR). The results showed that the addition of copper improved the dispersion of nickel and therefore facilitated the reduction of Ni at low temperature. The highest hydrogen selectivity of 70.6% is observed over the Ni-Cu/Al 2 O 3 catalysts at a steam/carbon ratio of 0.9. With Cu promotion, a gasoline conversion of 42.6% can be achieved at 550˝C, while with both Mo and Ce promotion, the gasoline conversions were 31.7% and 28.3%, respectively, higher than with the conventional Ni catalyst. On the other hand, initial durability testing showed that the conversion of gasoline over Ni-Cu/Al 2 O 3 catalysts slightly decreased after 30 h reaction time.

“…[10] Present commercialized stationary fuel cell In 1994 Jamal and Wyszynsky reviewed the onboard generation of hydrogen as an alternative fuel for combustion engines. [17] Applying hydrogen as a combustion fuel is still an attractive alternative; only slight modifications of spark ignition engines are necessary and car manufacturers have already demonstrated performing engines. The application of hydrogen for onboard fuel cells requires much purer hydrogen that can only be directly delivered in the desired purity by voltaic decomposition of water.…”

In the industrial production of hydrogen and of synthesis gas the water gas shift reaction represents an essential step for the overall process efficiency of the process by increasing the hydrogen yield and by adjusting the desired ratio of hydrogen and carbon monoxide for a subsequent synthesis step. In addition to that in fuel cell technology it is absolutely necessary to decrease the CO content of the fuel hydrogen due to the limited CO tolerance of present day fuel cell anodes. To be successful applying water gas shift catalysts in hydrogen production for fuel cells especially in automotive systems some major obstacles of the commercial Cu/Zn/Al catalyst systems must be overcome. Major new demands are reduction of volume and weight by two to three orders of magnitude, oxidation resistance and improved tolerance for steam condensation and poisons, here mainly sulfur present in gas feedstock and in gasoline. Precious metal catalyst systems on rare earth metal oxides are most promising and could fulfill the requirements in nonstationary applications were conventional catalysts are not applicable.

“…This manner is a way to produce hydrogen on-board in stead of carrying a massive hydrogen vessel in the vehicle for combusted in engine. This exhaust gas emission control concept has been originally applied to SI engines (Jamal & Wyszynski, 1994;Jamal et al, 1996). In a catalytic reformer, the exhaust gas reforming process takes place by injecting a portion of fresh fuel (reformer fuel) to react with an extracted exhaust gas stream to generate a hydrogen-rich reformed exhaust gas which is routed to mix with fresh intake charge before entering the engine combustion chamber; this method is called reformed exhaust gas recirculation (REGR).…”
