摘要: Abstract Pure hydrogen production is of great interest as it an energy carrier which can be used in PEM fuel cells for power production. Methane Steam Reforming (MSR) commonly although the produced not free other components. Membrane Reactors (MR) enable a pure product stream and allows reaction to take place at significantly lower temperatures (lower than 550 °C) conventional reactors (greater 800 °C) with comparable methane conversion. This achieved by removal through permselective Pd–Ag based membrane that cause favorable shift chemical equilibrium towards In present study, two-dimensional, nonlinear, pseudo-homogeneous mathematical model catalytic fixed-bed reactor steam reforming over nickel-based foam supported catalyst presented. Simulated results referring distribution species, conversion, temperature flowrate along different radial positions are obtained analyzed. The performance structured on configurations under same operating conditions also studied. Experimental facilitate identification suitable conditions.
