6-flow reactor: Catalyst testing in a multiphase-parallel packed-microreactor system

This thesis deals with the design and operation of a multiple-parallel powder-packed reactor with continuous gas and liquid flows for kinetic tests. The reactor design is discussed in detail. Subsequently, axial dispersion in a multiphase packed microreactor is treated. Also, it is described how to minimise segregation during the loading of a...

Deactivation of Hydroprocessing Catalysts: New insights in catalyst structure, activity and stability

In dit proefschrift is de deactivering van hydroprocessing katalysatoren onderzocht. Katalysatoren zijn hulpstoffen die gebruikt worden om chemische reacties te bewerkstelligen, zonder daarbij zelf verbruikt te worden. Een bekend voorbeeld is de uitlaatkatalysator in de auto, die o.a. onverbrande brandstofresten omzet in kooldioxide en water. In...
