Hydrodesulphurization process

Abstract

Abstract MESH-WIDTH OF SIEVES THAT RETAIN THE PARTICLES AND LET THEM PASS, RESPECTIVELY, SAID REACTING THREE-PHASE DISPERSION OCCUPYING ALL CAVITIES OF THE REACTION LOOP AND BEING SUBSTANTIALLY FREE OF CONCENTRATION GRADIENTS IN ALL PARTS OF THE REACTION LOOP; (B) WHILE MAINTAINING THE THREE-PHASE DISPERSION AND THE TEMPERATURE AND PRESSURE CONDITIONS FOR HYDROCONVERSION, CONTINOUSLY INTRODUCING INTO THE REACTION LOOP FEED STREAMS OF MEASURED AMOUNTS OF THE HYDROGEN-CONTAINING GAS, THE LIQUID OIL FEED AND THE PARTICULATE HYDROCONVERSION CATALYST; (C) SIMULTANEOUSLY HEREWITH CONTINOUSLY ALLOWING A CORRESPONDING AMOUNT OF A PRODUCT STREAM HAVING SUBSTANTIALLY THE SAME COMPOSITION AS THE REACTING THREE-PHASE DISPERSION TO FLOW FROM THE REACTION LOOP; AND (D) SEPARATING THE PRODUCT STREAM THUS FLOWING FROM THE REACTION LOOP INTO A HYDROGEN-CONTAINING GAS, A PRODUCT OIL AND A CONCENTRATED SLURRY OR PASTE OF THE PARTICULATE HYDROCONVERSION CATALYST IN OIL. 1. IN A PROCESS FOR THE CATALYTIC HYDROCONVERSION AT ELEVATED TEMPERATURE AND PRESSURE OF CRUDE OIL AND HEAVY PETROLEUM FRACTIONS, THE IMPROVEMENT COMPRISING THE STEPS OF (A) IN A REACTION LOOP, MAINTAINED AT HYDROCONVERSION CONDITIONS OF ELEVATED TEMPERATURE AND PRESSURE AND PROVIDED WITH INLETS, OUTLETS, MIXING DEVICES, AND A CIRCULATION PUMP, FIRST FORMING AND THEREAFTER MAINTAINING A REACTING THREE-PHASE DISPERSION CONSISTING OF A GASEOUS HYDROGEN CONTANING PHASE, A LIQUID PHASE OF THE OIL TO BE HYDROCONVERTED, AND A SOLID PHASE OF THE HYDROCONVERSION CATALYST IN PARTICULATE FORM RANGING IN SIZE FROM 0.02 TO 0.5 MM, MEASURED BY THE
