Abstract: Surface-active solid-phase catalyst activity may be substantially improved by creating deliberate repetitive surface-to-surface contact between portions of the active surfaces of catalyst objects. While they are immersed in reactant material such contact between portions of the active surfaces of catalyst objects can substantially activate the surfaces of many heterogeneous catalysts. Examples are given of such action employing a multitude of predetermined shapes, supported catalyst structures, etc. agitated or otherwise brought into contact to produce numerous surface collisions. One embodiment employs a gear pump mechanism with catalytically active-surfaced gear teeth to create the repetitive transient contacting action during pumping of a flow of reactant. The invention is applicable to many other forms for creating transient catalytic surface contacting action. Optionally catalytic output of such systems may be significantly further improved by employing radiant energy or vibration.
