Mixed-phase distributor for fixed-bed catalytic reaction chambers

Abstract

Distribution of a mixed-phase, vapor/liquid reactant stream to a fixed-bed of catalyst particles is accomplished through the use of a distributor tray in the form of a horizontal plate (or deck) having a plurality of vertically-disposed venturi-shaped eductors. The distributing device is installed within a substantially catalyst-free area of the reaction chamber and serves (i) to initially distribute the reactant stream as a froth to the reaction chamber and/or, (2) to distribute the effluent from one bed of catalyst particles to the next succeeding bed of catalyst particles.
