Abstract
Two model hydrogenations - alpha-methyl styrene (AMS) and polystyrene (PS) ? in novel reactors and under conditions were studied. The AMS hydrogenation reaction was carried out in vertically stacked monoliths mounted above a piston arrangement (POMR), thereby allowing oscillatory frequencies much higher than the solenoid configuration on the reactive extruder. This configuration can significantly enhance rates of mass transfer ? by as much as 700% - for the air-water system. Pulsing effects for the POMR with pretreatment 2 catalysts showed a rate enhancement of 84% at the maximum (17.5 Hz) frequency vs. no pulsing. The results showed that for a correctly pretreated catalyst, the enhanced mass transfer from the POMR due to flow pulsations over the catalyst surface can enhance reaction rates for gas mass transfer limited systems. This is an abstract of a paper presented at the AIChE Annual Meeting (Salt Lake, UT 11/4-9/2007).
