A distributor for use in a multiphase upflow reactor vessel comprises a horizontally disposed plate mounted in the vessel above the feed inlet port, and having a plurality of perforations therethrough and at least one downwardly extending tube passing through the plate. The perforations and tube are sized such that under equilibrium feed conditions a gas pocket forms below the plate having a height less than or substantially equal to the tube length. Substantially all of the feed gas passes through the plate perforations and substantially all of the feed liquid, or liquid and solids, passes through the tube. The vessel may contain catalyst beds and/or a plurality of the distributors in series, as illustrated. <IMAGE> |
