TY - JOUR N2 - A continuous increase in the greenhouse gases concentration due to combustion of fossil fuels for energy generation in the recent decades has sparked interest among the researchers to find a quick solution to this problem. One viable solution is to use hydrogen as a clean and effective source of energy. In this paper, an extensive review has been made on the effectiveness of metallic catalyst in hydrocarbon reforming for COX free hydrogen production via different techniques. Among all metallic catalyst, Ni-based materials impregnated with various transition metals as promoters exhibited prolonged stability, high methane conversions, better thermal resistance and improved coke resistance. This review also assesses the effect of reaction temperature, gas hour space velocity and metal loading on the sustainability of thermocatalytic decomposition TCD of methane. The practice of co-feeding of methane with other hydrocarbons specifically ethylene, propylene, hydrogen sulphide, and ethanol are classified in this paper with the detailed overview of TCD reaction kinetics over an empirical model based on power law that has been presented. In addition, it is also expected that the outlook of TCD of methane for green hydrogen production will provide researchers with an excellent platform to the future direction of the process over Ni-based catalysts. © 2018 Hydrogen Energy Publications LLC IS - 41 ID - scholars9881 KW - Association reactions; Catalysts; Ethylene; Fossil fuels; Greenhouse gases; Methane; Reaction kinetics; Sulfur compounds; Transition metals KW - Catalytic decomposition of methanes; Co-feeding; Gas hour space velocity; Hydrocarbon reforming; Metallic catalysts; Methane conversions; Process parameters; Thermocatalytic decomposition KW - Hydrogen production A1 - Syed Muhammad, A.F.
