Abstract
An improved random-dumped packed bed for effecting inter-phase heat and mass transfer. The packed bed is a plurality of a first packing size substantially uniformly mixed and co-mingled with a plurality of the suitable second larger packing size. The mixed bed so formed provides the additional surface area and mass transfer capacity of the plurality of the added first smaller packing size while maintaining the gas and liquid limiting flow capacity of a bed of the second larger packing size absent the smaller first packing size.
