The Flow of Reactive Fluids through a Packed Bed

This paper concerns a numerical simulation of a flow of reactive multicomponent gas through a packed bed consisting of catalyst beads which is used in various chemical apparatuses such as a fuel cell reformer. The aim of this simulation is to clarify the effect of change of area along the channel on the flow pattern of each component, in order to investigate the deposition of carbon for the reformation of hydrocarbon -steam mixture in the reformer. It is found that the deposition is apt to occur near the throat of the channel and its probability is higher for a propane-steam mixture than for a methane-steam mixture.
