An improved random-dumped packed bed for effecting inter-phase heat and mass transfer, wherein the packed bed is comprised of a plurality of a first packing size substantially uniformly mixed and co-mingled with a plurality o f 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 flo w capacity of a bed of the second larger packing size absent the smaller first packing size.
