Hydrogen Production from Methane Steam Reforming in Combustion Heat Assisted Novel Microchannel Reactor with Catalytic Stacking

In this study, we further investigate the application of an MCR containing a nickel metal catalyst with variable number of stacks for hydrogen production via MSR. Microchannels were contained in the MCR one side of the nickel metal catalyst with variable number of stacks for producing hydrogen to generate the necessary heat for the endothermic MSR and the combustion reaction was performed on the other side of the MCR The catalyst used in this study for the MSR reaction, which was a prepared Pd[0.1]-Al[0.3]/Ni catalyst. The methane conversion and hydrogen production mole ratio were 94.7% and 9.39 mol h(-1), respectively, and the steam/carbon (S/C) ratio was 3 at 650 degrees C, GHSV = 10 000 h(-1). The promise of a feasible simplified system for hydrogen production from the MSR was confirmed. If a hydrogen separation membrane is placed between the MSR elements in an MCR, the forward reaction will be preferentially promoted by the rapid removal of the hydrogen produced through the MSR reaction.
