TLDR
In this paper, a gas liquid or a gas-liquid solid feed is contacted in a vessel containing a packed bed of contact particles, and at least a portion of the feed is passed upwardly through the packed bed and the mass flow rate is periodically increased sufficiently to cause a portion within the vessel to form an expanded region within the packed beds.Abstract:
