Hydrodynamic Effect on the Iso-octane Steam-Reforming in a Monolithic Reactor Channel

Abstract

The production process of clean hydrogen by iso-octane steam reforming in a micro-reactor under atmospheric pressure, and the high temperature was investigated. The simulation is modeled using momentum conservation, mass conservation, and convection-diffusion equations, represented by the Navier-Stocks equations, the continuity equation, and the Steffan-Maxwell equation respectively. The resolution was performed using the COMSOL Multiphysics 3.5a software. This discretizes the differential equations into their conservative form by the finite element method using an unconditionally stable scheme. An analysis of the hydrodynamics of the flow effect shows that the hydrogen produced by iso-octane reforming is proportional to the mixed flow Reynolds number.
