New structure for improved catalytic results

Catalytic processes in industry are often conducted using packed bed pellets. Limitations presented include limited mass and heat transfer due to available surface constraints of the pellets. And although the reduction in pellet size can overcome this drawback, one often sees that this is accompanied by an undesired effect of pressure drop over the catalyst bed.

In order to accommodate structures allowing increased catalytic conversions, macroporous catalysts were developed having an inert structured support coated with an active catalyst layer. Monolith foam and honeycomb structures with a thin catalytic coating are well known in this respect. These usually show significantly lower pressure drops and have good mass and heat transfer properties, but the amount of catalyst per reactor volume often remains inadequate.Inherent catalytic structures may then be a good solution, where the active catalytic component is incorporated into the monolith structure. These have proven to function well in most catalytic reactions.
