Packed beds are important in the chemical industries in separations and as catalytic reactors. The standard approach to modeling the complex particle/tube arrangement is to employ an effective medium approach with one-dimensional flow and lumped transport parameters. Simplification of the flow and estimation of the transport quantities is usually by experiment and empiricism. Computational flui...

Packed bed reactors with diameters below 1 cm, millipacked beds hereafter, are often used to test catalysts. The prospect of using these for catalytic kinetic measurements is quite attractive, but it requires a better knowledge the flow characteristics reactors. This study focuses on main hydrodynamic features in single phase gas flow. effects length, velocity, reactor/particle diameter ratio (...

A pseudo-homogeneous model, considering the axial and radial heat mass transfer characteristics of an oxidative coupling methane (OCM) packed-bed catalytic reactor, was utilized to represent its thermal reaction performance in a wide range variation operating conditions investigated this research. This is another step towards distinguishing direct contribution reactions indirect reactor's struc...
