Experimental design methodology for optimising catalytic performance of Ni/Ce/α-Al 2O 3 catalyst for methane steam reforming

The performance of a Ni/Ce/a-Al2O3 catalyst was optimised using a central composite design methodology to enhance hydrogen production and methane conversion in the catalytic steam reforming of methane. The influence of temperature, the presence of weight per cent Ni and Ce in the a-Al2O3 catalyst su...
