摘要
A gas-liquid or a gas-liquid-solid feed is contacted in a vessel containing a packed bed of contact particles. At least a portion of the feed is passed upwardly through the packed bed and the mass flow rate of the feed is periodically increased sufficiently to cause a portion of the particles within the vessel to form an expanded region within the packed bed.
