摘要： FROM THE VESSEL. THE VESSEL COMPRISES A SPHERICAL SHELL HAVING A HORIZONTAL GRID MOUNTED IN THE LOWER PART OF THE SHELL ON WHICH AN EXPANDABLE PARTICULATE CATALYST IS SUPPORTED. A FEED CONDUIT FOR PASSING HYDROCARBON OIL FEEDSTOCK AND HYDROGEN CONTAINING GAS IS CONNECTED TO THE BOTTOM OF THE VESSEL AND OPENS INTO THE VESSEL BELOW THE GRID. A LIQUID DRAWOFF CONDUIT IS CONNECTED TO THE VESSEL AND OPENS BELOW THE MIDPOINT OF THE VESSEL, AND PREFERABLY ABOVE THE LEVEL OF THE EXPANDED CATALYST BED. A SECOND HORIZONTAL GRID IS HORIZONTALLY MOUNTED IN THE UPPER HALF OF THE SPHERICAL VESSEL AND ACTS TO SUPPORT FIXED CATALYST BED FOR HYDROTREATING HYDROCARBON VAPOR A VAPOR EFFLUENTS WITHDRAWAL CONDUIT IS CONNECTED TO AND OPENS INTO THE REACTOR ABOVE THE FIXED CATALYST BED.
A PROCESS FOR THE HYDROTREATING OF HYDROCARBON OIL AND THE APPARATUS THEREFOR ARE DISCLOSED HEREIN. THE PROCESS COMPRISES FEEDING A HEAVY HYDROCARBON OIL FEED AND A HYDROGEN CONTAINING GAS INTO THE BOTTOM OF A HIGH PRESSURE, HIGH TEMPERATURE SPHERICAL REACTOR VESSEL, PASSING THE OIL AND GAS UPWARDLY THROUGH AN EXPANDED PARTICULATE CATALYST BED IN THE LOWER HALF OF THE VESSEL THEREBY RAPIDLY DECREASING THE UPWARD VELOCITY OF THE UPWARDLY FLOWING GAS AND OIL AND REMOVING THE TREATED HYDROCARBON OIL AT A RATE SUFFICIENT TO MAINTAIN THE UPPER LEVEL OF THE LIQUID HYDROCARBON OIL APPROXIMATELY AT THE MIDPOINT OF THE SPHERICAL VESSEL. PREFERABLY VAPOR PRODUCT IS PASSED UPWARDLY IN THE VESSEL THROUGH A SECOND FIXED CATALYST BED FOR ADDITIONAL HYDROTREATING PRIOR TO BEING WITHDRAWN-

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.

摘要： A PROCESS FOR TREATING HEAVY HYDROCARBON OIL WITH HYDROGEN GAS AT HIGH PRESSURES AND TEMPERATURES IN THE PRESENCE OF PARTICULATE CATALYSTS IS DISCLOSED HEREIN. THE PROCESS COMPRISES FEEDING THE HEAVEY HYDROCARBON OIL, PREFERABLY A VACUUM OR ATMOSPHERIC RESIDUUM, HYDROGEN GAS AND FINE PARTICULATE CATALYST IN THE SIZE RANGE OF UP TO ABOUT 600 MICRONS UPWARDLY THROUGH AN EXPANDED BED OF COARSE PARTICULATE CATALYST RANGING INSIZE FROM ABOUT 1/33 TO ABOUT 3/8 INCH AT A SUFFICIENT VELOCITY TO MAINTAIN THE BED IN AN EXPANDED, RANDOM MOTION STATE, REDUCING THE UPWARD VELOCITY OF THE HYDROCARBON OIL, HYDROGEN GAS AND FINE PARTICULATE CATALYST ABOVE THE EXPANDED COARSE CATALYST BED TO A VELOCITY SUFFICIENT TO ESTABLISH AN EXPANDED FINE CATALYST BED, AND WITHDRAWING THE TREATED HYDROCARBON OIL AND EFFLUENT GASES FROM THE HIGH PRESSURE, HIGH TEMPERATURE ZONE ABOVE THE FINE CATALYST BED.

摘要： A PROCESS FOR HYDROTREATING A HEAVY HYDROCARBON OIL AND A HIGH PRESSURE, HIGH TEMPERATURE REACTOR VESSEL OR PRACTICING THE PROCESS IS DISCLOSED HEREIN. THE REACTOR IS CONSTRUCTED OF A VERTICALLY MOUNTED CYLINDRICAL SHELL WITH A SPHERICAL SHELL ATTACHED TO THE UPPER END OF THE CYLINDRICAL SHELL. PREFERABLY A TRANSVERSE GRID IS MOUNTED IN THE LOWER END OF THE CYLINDRICAL SHELL WITH A FEED CONDUIT OPENING INTO THE CYLINDRICAL SHELL BELOW THE GRID, AND LIQUID WITHDRAWAL AND GASEOUS EFFLUENT CONDUITS EXTENDING INTO THE REACTOR AND OPENING IN THE SPHERICAL SHELL RESPECTIVELY BELOW AND ABOVE THE LIQUID REACTANT LEVEL IN THE REACTOR. APPARATUS AND PROCESS ARE ALSO SHOWN FOR SEPARATING LIQUID COMPONENTS FROM THE EFFLUENT AND RECYCLING SEPARATED GASES, PRINCIPALLY HYDROGEN, TO THE REACTOR FEED CONDUIT. THE PROCESS INCLUDES TREATING A HYDROCARBON LIQUID WITH A HYDROCARBON-CONTAINING GAS AT HIGH PRESSURE AND HIGH TEMPERATURE (I.E., ABOVE 658*F. AND 1000 P.S.I.G.) IN THE PRESENCE OF A FINELY DIVIDED PARTICULATE CATALYST BY PASSING UPWARDLY IN THE VESSEL A MIXTURE OF THE LIQUID AND GAS THROUGH THE PARTICULATE CATALYST AT A FLOW VELOCITY SUFFICIENT TO MAINTAIN THE CATALYST IN AN EXPANDED STATE, AND SUBSEQUENTLY REDUCING THE UPWARD FLOW VELOCITY OF THE MIXTURE TO BELOW THAT WHICH THE LIQUID AND PARTICULATE CATALYST MATERIAL ARE CARRIED UPWARD BY THE GAS, BY INCREASING THE CROSS-SECTIONAL AREA OF THE FLOW.
