    摘要： In an ebullated bed process reactor effluent is subjected to high pressure followed by intermediate flash separation. An ebullation liquid is formed by educting high pressure flash separation liquid into an intermediate flash separation liquid. The ebullation liquid is recycled to the reactor to expand the catalyst bed to 110 vol % to 200 vol % of a settled catalyst bed volume. As a result of recycle pressure balance is advantageously maintained. Carry over catalyst and catalyst fines are recycled to the reactor and kept out of downstream equipment.

    摘要： An improved air distribution device for distributing fluidizing gas to a bed of fluidized solids. The distribution device is arranged to maintain a bed of fluidized particles above a planar region of air injection and allow withdrawal of solids from below the region of air injection. The fluidizing gas is distributed to a bed of fluidized particles by a central dome and a series of horizontally extending branch pipes arranged about the periphery of the dome. In order to improve the structural integrity of the apparatus and the operation of the device, the horizontal branch pipes are attached to a knuckle region of the central dome by a series of extruded outlets that minimize stress concentrations in the branch pipe connection and locate outlet holes in the branch pipes at an elevation close to the outlet holes in the dome.

    摘要： A process and apparatus are shown for the improved utilization of catalysts in a hydrocracking system. The method comprises passing a hydrocarbon oil feedstock, preferably a heavy hydrocarbon residuum, upwardly through a particulate catalyst bed in a reaction zone maintained at high temperature and high pressure, together with hydrogen-containing gas; recycling a portion of the upwardly flowing oil together with a portion of the particulate catalyst to the bottom of the reaction zone while simultaneously pulverizing the minor proportion of the particulate catalyst to a fine powdered catalyst; and passing the recycled oil and finely powdered catalyst upwardly through the particulate catalyst bed in the reaction zone, with at least a portion of the powdered catalyst leaving the reactor with the treated effluent. Apparatus for practicing this process comprises a reactor vessel having a vertically mounted recycle conduit mounted therein, and pulverizing means, preferably a modified axial turbine high-shear mixer communicatingly connected to the bottom of the recycle conduit, for pulverizing recycled particulate catalyst to a fine powdery catalyst. Additionally, a pump is mounted to the outlet of the high-shear turbine mixer to provide positive fluid flow.
