“…The problem associated with CO in H 2 stream can be avoided by catalytic decomposition of methane. The catalytic decomposition of methane (CDM) over Ni based catalysts is extensively studied systems due to the growing importance on the production of pure H 2 as well as the formation of useful compounds such as carbon nanotubes (CNT) and carbon nanofibers (CNF) [2][3][4][5][6]. On economical perspective the H 2 production rate and the CNF or CNT synthesis are equally important.…”

In this present paper, we report catalytic decomposition of methane over Ni/HY catalysts, with varying Ni loading at 550°C and atmospheric pressure. The relationships between catalyst performance and characterization of the fresh and used form of catalysts are discussed from the data obtained by scanning electron microscopy, X-ray diffraction analysis, temperature programmed reduction, O 2 pulse chemisorption and carbon elemental analyses. It is observed that, the catalytic activity of Ni/HY catalysts is high at initial stages and gradually decreased with time and finally deactivated completely. The yield of hydrogen and carbon nanofibers is strongly dependent on Ni loading. It is found that 20 wt% Ni/HY catalyst showed higher hydrogen yield over the other loadings.

“…However, we expected that 60% of methane would provide quicker deactivation. Villacampa et al (2003) describes that, for Ni/Al 2 O 3 catalysts, the presence of hydrogen would prevent the formation of carbon encapsulated without decreasing the reaction rate for hydrogen production. The results obtained in the present work could be explained by the increased formation of hydrogen with higher contents of methane.…”

Abstract:A growing interest in hydrogen use has been observed due to its environmentally friendly characteristics. However, the current methods of hydrogen production from natural gas are based on steam methane reforming, partial oxidation, and autothermal reforming. These processes produce a mixture of hydrogen and carbon oxides and after water-gas shift reactions, in order to increase the production of hydrogen, a large amount of cO 2 is generated and possibly released in the atmosphere. In this context, the catalytic methane decomposition has been receiving attention as an alternative route to the production of cO x -free hydrogen. It has been reported that the appropriate group of catalysts and reactors can lead to a viable process. current investigations attempt to increase the yield of hydrogen. The present work aims to evaluate the processes currently used for that and to present the preliminary results obtained with cobalt catalysts for methane decomposition. A comparison between the conventional processes and the suggested ones is made, and the major advantages in the use of methane decomposition are presented.
