Abstract: HYDRODESULFURIZATION CATALYSTS WHICH ARE NORMALLY MANUFACTURED FOR USE IN THE HYDROCONVERSION OF RESIDUAL OILS TO LIGHTER BOILING PRODUCTS CONSIST OF MIXTURES OF RELATIVELY POROUS AND RELATIVELY NONPOROUS CATALYST PARTICLES AS A FUNCTION OF THE MANUFACTURING PROCEDURE. IN THE EBULLATED PROCESS, FOR HIGH CONVERSION LEVEL OPERATIONS, THERE IS A CRITICAL LIMIT TO THE AMOUNT OF NONPOROUS CATALYST PARTICLES THAT CAN EXIST IN A MIXTURE BEFORE THE DEFLUIDIZATION OF THE CATALYST SYSTEM OCCURS. IN USING MICROSPHEROIDAL OR EXTRUDATE CATALYST, THE AMOUNT OF NONPOROUS CATALYST CONTAINED IN THE CATALYST BED TO THE UNIT IS LIMITED TO ABOUT 10% BEFORE DEFLUIDIZATION OF THE CATALYST SYSTEM SETS IN WHEN OPERATING AT CONVERSION LEVELS EXCEEDING 60%.

Abstract: A multi-stage process for the hydrodesulfurization of high metals content hydrocarbon feed materials wherein the first reaction zone is an ebullated bed contacting system using a powdered contact agent having particles in the size range from 40 to 325 U. S. mesh whereby superior metals removal is effected. The reduced metals content effluent is passed to subsequent stages wherein deep desulfurization is obtained due to low metals contamination of the catalyst. Build up of carryover contaminated catalyst from the first reaction zone is prevented by either an intermediate catalyst separation step between zones or use in the subsequent zones of ebullated bed systems incorporating catalyst of sufficiently large particle size whereby the powdered first zone catalyst is carried through and out of the subsequent zones.

Abstract: A HIGH CONVERSION HYDROGENATION PROCESS FOR CONVERING A PETROLEUM RESIDUUM HAVING AT LEAST 25 PERCENT BY VOLUME BOILING ABOVE 975* F. TO MATERIAL BOILING BELOW 975* F. TAKES PLACE IN A SERIES OF EBULLATED BED REACTORS. AT LEAST 65 PERCENT OF THE METALS IN THE RESIDUUM FED TO THE FIRST REACTOR IS DEPOSITED ON THE CATALYST IN THE FIRST REACTOR. THE REACTORS ARE OPERATED WITHIN 25* F. OF ONE ANOTHER TO ACCOMPLISH THIS. THE RATIO OF THE PRODUCTS BOILING IN THE 392* TO 750: F. RANGE IS MAINTAINED AT LESS THEN TWICE THAT OF THE PRODUCTS BOILING IN THE C4 TO 392* F. RANGE.

Abstract: Coker feedstocks having minimum amounts of sulfur or metals are produced from residuum feeds using an ebullated bed reaction zone. The qualities of the coker feedstocks are controlled through the use of selected operating conditions within the limits of converting 30 to 60 percent of the material in the feed boiling above 975* F to lighter boiling products.
