    摘要： Kerogen is recovered from oil shale deposits by introducing CO2 and H2S in water into the deposits under pressure and then shutting in the deposits to allow the H2S and CO2 solutions to dissolve the inorganic matrix material in the deposits. Kerogen is then recovered from the deposits, preferably as a colloidal suspension.

    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.
