The effect of noble metals on catalytic methanation reaction over supported Mn/Ni oxide based catalysts

Carbon dioxide (CO2) in sour natural gas can be removed using green technology via catalytic methanation reaction by converting CO2 to methane (CH4) gas. Using waste to wealth concept, production of CH4 would increase as well as creating environmental friendly approach for the purification of natura...
