ABSTRACT:
A distillation column reactor is provided having special trays arranged within the column to provide better mixing and thus achieve better mass and energy transfer between the liquid, vapor and catalyst. The trays comprise a slotted support plate for the catalyst with openings to allow vapor passage through the catalyst from the tray below. A draft chimney or riser is provided directly above the slotted openings to increase the vapor velocity and carry the liquid and catalyst upward on the tray. A hood is included at the upper end of the chimney to direct the liquid-vapor-catalyst flow back down onto the tray. The liquid from the tray above is distributed onto the tray about the chimney by distributors which preferably extend below the static catalyst level on the tray.
