Laboratory Evaluation of the Attrition Resistance of FCC Catalysts

In this preliminary work, simulation of the flow and collision of particles using a coupled DEM (Discrete Element Method) and CFD (Computational Fluid Dynamics) in a Jet Cup is performed to investigate the basics of attrition. This allows to evaluate the distribution of contract forces and how it is affected by various operating and design parameters of the geometry. This can be correlated to the fraction of particles that will break.
