Confined plunging liquid jet reactor with modified downcomer

A confined plunging liquid jet reactor with modified downcomer, comprising:

• a downcomer having an upper end, an open lower end, and a gas inlet for receiving gas from an external source, the downcomer defining a hollow column;
• a porous screen extending transversely across the hollow column defined by the downcomer;
• a nozzle mounted on the upper end of the downcomer, the nozzle being adapted for receiving a pressurized liquid from an external source and configured to generate a liquid jet downward in the hollow column, the porous screen being below the nozzle;
• and
• a receiving tank adapted for holding a liquid reservoir having a surface, the open lower end of the downcomer being positioned in the liquid reservoir with the surface rising in the column to a level below the nozzle such that the jet of pressurized liquid creates turbulence and bubbles of gas in the liquid reservoir when the jet impacts the surface of the liquid reservoir to entrain the gas in the liquid reservoir, the porous screen preventing coalescence of bubbles and keeping bubble size small to prevent disentrainment of gas from the liquid reservoir and increase entrainment of gas in the liquid reservoir.
