Experimental and Simulation Study on Coproduction of Hydrogen and Carbon Nanomaterials by Catalytic Decomposition of Methane-Hydrogen Mixtures

چکیده
Among all hydrocarbons, the methane molecule contains highest amount of hydrogen with respect to carbon. Therefore, catalytic decomposition is considered as an efficient approach produce along nanostructured carbon product. On other hand, presence in composition initial gas mixture required for stable operation catalyst. In present work, experiments on methane–hydrogen were performed a flow-through quartz reactor equipped McBain balances under atmospheric pressure. The catalyst NiO-CuO/Al2O3 was prepared by mechanochemical activation technique. maximum yield 34.9 g/gcat obtained after 2 h experiment at 610 °C. An excess reaction provided long-term activity nickel–copper durability tests ongoing 6 within temperature range 525–600 °C showed no noticeable deactivation Two kinetic models, D1a and M1a, proposed studied over constants these models determined means mathematical modelling.

Methane Decomposition: Production of Hydrogen and Carbon Filaments
Hydrogen, presently, finds application as a chemical rather than a fuel in commercial operations. However, being a non-polluting source of energy, hydrogen is predicted to be the ‘‘fuel of the future’’. One of the most potential applications for hydrogen is to power fuel cells. Major automobile manufacturers are currently working towards developing fuel cell vehicles; such vehicles are expected...
