New! Web Lab with interactive simulation of dynamic reaction-diffusion in a porous catalyst.
These are links to resources for a graduate course in CRE. Topics include dynamics of CSTRs, surface reaction kinetics, reaction and diffusion in porous catalysts, and reaction and diffusion in Chemical Vapor Deposition (CVD).
