Syngas Production from Combined Steam and Carbon Dioxide Reforming of Methane over Ce-modified Silicasupported Nickel Catalysts

This study investigates the physicochemical attributes of Ce-modified Santa Barbara Amorphous-15 (SBA-15) supported Ni catalyst and evaluates its catalytic performance for combined steam and CO2 reforming of methane in order to produce synthesis gas. Both 10 % Ni/SBA-15 and 10 % Ni/Ce-SBA-15 catalys...
