1. Connecting Catalytic Chemistry to External Particle Conditions via CFD Anthony G. Dixon, Department of Chemical Engineering, Worcester Polytechnic Institute
Our objective is the more realistic treatment of catalyst particle internal transport and reaction processes by linking them
to the conditions in the fluid flowing past and surrounding the particle. We use computational fluid dynamics to simulate these processes. Our work this year has illuminated the effects of external gas flow on the supply and consumption of reactants in steam reforming.
Single particle
Angle of flow changes flow and fluxes to surface, which induces asymmetrical reactant distribution inside the catalyst particle
YCH4
Group of particles
CFD Simulation shows regions of
slow flow between particles
Slow flow leads to regions of reactant depletion in the particles, which could give different chemistry
