Research output: Contribution to journalArticlepeer-review


A new isothermal single pellet diffusion reactor is developed for reaction engineering studies under severe intraparticle mass transfer limitations. It is equipped with two operational modes for analyzing the centerplane concentration: Attenuated Total Reflectance-FTIR, and GC analysis. With benzene hydrogenation on nickel/kieselguhr as a model reaction, several studies are underway: reactor transient and steady state behavior, kinetic and diffusivity modeling, and induced activity gradients.
