Thermo Catalytic Decomposition of Methane over Cu – Al2O3 and 5 – 20wt% Ni – Cu – Al2O3 Catalysts to Produce Hydrogen and Carbon Nanofibers: Experimental Investigation

Hydrogen is an environmentally beneficial fuel with the potential to reduce the use of fossil fuels greatly; yet, it faces numerous important difficulties before it can be widely adopted. TCD (thermo catalytic decomposition of methane) is one of the most useful strategies for fulfilling future demand and, as a result, an appealing approach for COx-free hydrogen synthesis, which is necessary in fuel cells. The combustion of fossil fuels produces a large amount of greenhouse gases such as carbon dioxide, nitrogen oxides, and sulphur oxides. We attempted to create hydrogen utilising Cu-Al2O3 and 5, 10, 15, and 20% wt% Ni modified Ni/Cu-Al2O3 catalysts in this study. Cu-Al2O3 catalysts with 5 wt percent Ni/Cu-Al2O3 catalysts with 20 wt percent Ni/Cu-Al2O3 catalysts with 15 wt percent Ni/Cu-Al2O3 catalysts with 10 wt percent Ni/Cu-Al2O3 catalysts with 10 wt percent Ni/Cu-Al2O3 catalysts with 10 wt percent Ni/Cu-Al2O3 catalysts with 10 It has been discovered that increasing the nickel loadings in Ni/Cu-Al2O3 improves the efficiency of thermo catalytic methane breakdown. The 10wt% Ni/Cu-Al2O3 catalyst has the best catalytic activity of the five produced catalysts. Carbon nanofibers are seen in SEM pictures of catalysts after methane thermocatalytic breakdown. Cu-Al2O3 and 5,10,15, and 20% Ni/Cu-Al2O3 catalysts’ XRD patterns exhibited highly crystalline peaks, which could explain the improved catalytic life and production of carbon nanofibers. With a 10wt% Ni/Cu-Al2O3 catalyst, a 70 percent hydrogen production rate was recorded, and hydrogen carbon fibres were discovered, which can be employed as catalyst support.
