Production of Hydrogen from the Reforming of Methane Using a Plasma-Catalyst Approach
In this study, reforming of methane to hydrogen-rich fuel in an atmospheric-pressure microwave plasma-Ni/Al2O3 hybrid reactor was demonstrated. Experimental results showed that the nickel catalysts could be heated to 750 by the effluents that flowed through the discharge zone. The results showed the conversion of methane and the selectivity of hydrogen using plasma/catalyst approach were higher than that of without catalysts. At the inlet concentration of methane=5%, 1.4 kW and 12 slm, the selectivity of hydrogen reached 86.6% with the conversion of methane being 93.2%. The other gaseous byproducts were C2H2 (minor) with trace of C2H4 and HCN. In addition, large amounts of nano carbon black particles, which consisted of mainly C atoms and had a graphite-rhombohedral structure with a particle size of about 30 nm, were produced. The selectivity of carbon black reached 60.1%.
