Abstract: IN A METHOD FOR CATALYTIC HYDRODESULFURIZATION OF A HEAVY PETROLEUM HYDROCARBON OIL IN A REACTOR COMPOSED OF A CYLINDRICAL PRESSURE VESSEL AND A CYLINDRICAL INNER PIPE, IN WHICH HYDROGEN GAS, OIL LIQUID AND SOLID CATALYST PARTICLES ARE CONCURRENTLY PRESENT AND THE CATALYST PARTICLES ARE FLUIDIZED AND RECYCLED IN THE REACTOR WITHOUT FLOWING OUT OF THE REACTOR, AN IMPROVEMENT FOR THE PREVENTION OF THE CATALYST''S EFFLUX IS ACHIEVED BY THE PROVI-

SION OF A BUBBLE-COLLECTING PLATE AND A CATALYST PARTICLESCATCHING PLATE ABOVE THE INNER PIPE IN THE REACTOR.

Abstract: AN IMPROVED METHOD IS DISCLOSED FOR DISCHARGING PARTICULATE SOLIDS FROM A HIGH PRESSURE VESSEL, WHICH METHOD IS CHARACTERIZED BY MAINTAINING SAID PARTICULATE SOLIDS IN FLUIDIZED STATE IN ADMIXTURE WITH FLUIDS AND THUS KEEPING THE HEAD OF THE PARTICULATE SOLID-FLUIDS AND THUS IN THE VESSEL AND ITS PRESSURE DIFFERENTIAL GREATER THAN THE HEAD OF A CONDUIT CONDUCTING THE FLUID.
