ABSTRACT :This research revealed that exposure of methane and/or steam to radiowave (RW) and microwave (MW) energy using copper and rhodium catalysts produced hydrogen gas in high quantity. The feasible pathways of chemical reactions leading to its production are shown below ; CH4 + 2H2O + MW or RW + catalyst → CO2 + 4H2 4H2O + MW or RW + catalyst → 2O2 + 4H2 The generation of hydrogen gas was true for both sources of energy whether separately or in combination. The amount of hydrogen produced using RW energy was however, greater by more than 53 % as compared to the output of hydrogen using MW energy. MW at 1, 145 W power using 18.3 g rhodium catalyst yielded an average of 15,000 ppm hydrogen. Using RW energy, the same quantity of rhodium catalyst net a very high yield of 542,151 ppm hydrogen. Using 153.3 g copper catalyst, RW produced an average amount of 30,820 ppm hydrogen gas. For RW the optimum conditions for the above reactions to move forward and yield the highest amount of hydrogen gas, were the following; methane average gas flow rates of 1.0 ml/s, average steam flow rates of 5 g/s, radiowave coil glow time of 1 minute and /or greater. For MW, time range of 4 to 5 minutes at a power of 500 to 600 W was observed optimum. RW generator at 475 kHz and a coil glow time of 1 minute and higher gave peak of hydrogen gas generation. In general, methane as well as, steam or in right combinations studied on both, when subjected to MW and/or RW energy in the presence of catalyst(s) produced continuous generation of hydrogen gas.
