Modeling Fixed Bed Membrane Reactors for Hydrogen Production through Steam Reforming Reactions: A Critical Analysis

Cyclic Regeneration of Cu/ZnO/Al2O3 Nano Crystalline Catalyst of Methanol Steam Reforming for Hydrogen Production in a Micro-Fixed-Bed Reactor

Hydrogen can be produced for fuel cell applications by using methanol steam reforming reaction. In this article, a method was developed for regeneration of accelerated deactivated methanol-steam-reforming catalyst. Successive deactivation–regeneration cycles were studied in a 250 hours test for the first time including 6 regeneration cycles. It is shown that regeneration of the catalyst in ...

Steam reforming of propane over Ni-K/CeO2-Al2O3 catalyst in fluidized- and fixed-bed reactors under low steam to propane ratio

Fluidized bed was employed to investigate propane steam reforming over Ni-K/CeO2-Al2O3 catalyst. The catalyst was characterized by XRD, SEM, TG/DTA, and N2 adsorption-desorption tests. Effects of promoters, space velocity, temperature, and steam/propane (S/C) ratio on propane conversion, H2 yield, H2/CO ratio, and stability were studied and discussed. The experiments were carried out under cond...

Parametric Study of Hydrogen Production from Ethanol Steam Reforming in a Membrane Microreactor

Microreactors are miniaturized chemical reaction systems, which contain reaction channels with characteristic dimensions in the range of 10-500 μm. One possible application for microreactors is the conversion of ethanol to hydrogen used in fuel cells to generate electricity. In this paper a rigorous isothermal, steady-state two-dimensional model was developed to simulate the behavior of a membr...
