Pulse dynamic visualization in foam packed reactors - flow path evolution


Pulse dynamic visualization in foam packed reactors - flow path evolution

Zalucky, J.; Rabha, S. S.; Schubert, M.; Hampel, U.

In co-currently downward operated packed bed reactors, pulse flow is well known for its performance enhancing effects. Though suffering from a lot higher pressure drop than trickle flow, it offers the high advantage of continuous re-wetting, liquid flow re-routing and enhanced mass transfer due to higher, liquid induced shear stress. In our contribution, the evolution of liquid flow is addressed and visualized by the used of our ultrafast X-ray computed tomography system. As novel catalyst internal, foam blocks made of silicon infiltrated silicon carbide (SiSiC) were investigated.
