A method and an apparatus for promoting gas-liquid reaction in a reactor comprise pumping the reacting liquid to a predetermined height in a flow conduit. Gas is admitted to the liquid flow course to affect entraining gas in the flowing liquid and forming a gas-liquid mixture in the flow conduit. Said gas-liquid mixture is then guided to flow downwardly in a sustaintially vertical tube and subsequently discharged in a submerged eductor means for inducing a secondary circulating flow in the reactor. The circulating flow of the reactor liquid disperses the discharged gas homogeneously throughout the reactor and promotes a effective gas-liquid mass transfer.

A process for promoting gas-liquid reaction in a reactor comprising the steps of; continuously circulating liquid contained in a reactor by removing the liquid by a pump within a recirculating conduit circuit; pumping said liquid to a substantially vertical return conduit in said circuit, said return conduit extending a predetermined height above the liquid, said height being sufficiently high that is produces a low pressure section in the return conduit; admitting said gas to said flow conduit at said low pressure section to entrain said gas in said conduit and forming a gas-liquid mixture therein downstream of the gas entrainment; guiding said gas-liquid mixture flowing downwardly return conduit; injecting said gas-liquid mixture from the lower end of said return conduit in at least one eductor means below said liquid surface, said eductor means being submerged in said liquid with its inlet and outlet open to said liquid of said reactor, utilizing the injecting flow of said mixture as driving jet to induce a secondary flow in said liquid of said reactor through said eductor means; whereby the gas bubbles contained in said injecting flow further mix with said secondary flow in said eductor means and subsequently flow in the main body of the reactor liquid, wherein said gas continuously contacting with said liquid of said reactor while rising up to said liquid surface.
