Abstract: THE DEGREE OF HYDROGENATION OF BITUMEN DERIVED FROM TAR SANDS OBTAINED IN AN UPFLOW LIQUID PHASE REACTOR IN WHICH A HYDROCRACKING REACTION IS BEING CARRIED OUT FOR THE PRODUCTION OF AN UPGRADED SYNTHETIC PETROLEUM STOCK IS A FUNCTION OF THE AMOUNT OF NATURALLY OCCURRING SOLIDS COMPONENT IN THE TAR SANDS. IN SOME CASES A SUPPLEMENTAL
CATALYST IS REQUIRED TO ASSURE ADEQUATE HYDROGENATION AND AVOIDANCE OF COKE IN THE REACTOR.-

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 translation: 一种用于高金属含量烃进料的加氢脱硫的多阶段方法，其中第一反应区是使用粉末状接触剂的沸腾床接触体系，所述粉末接触剂的尺寸范围为40至325U.S.网，从而实现了优异的金属去除。 还原的金属含量流出物被传递到随后的阶段，其中由于催化剂的低金属污染而获得深度脱硫。 通过区域之间的中间催化剂分离步骤或在随后的沸腾床系统的区域中加入掺入具有足够大粒度的催化剂的方法来防止来自第一反应区域的残留污染的催化剂的积聚，由此将粉末状第一区催化剂输送出去 的后续区域。

Abstract: In the H-Coal process for coal hydrogenation, an initial step is the preparation of a coal slurry for transfer by suitable means into the pressurized reactor. This invention provides an improved method for facilitating such slurry transfer by pumping, and uses a recycled carried liquid to help provide a dilute easily pumpable coal slurry which is pressurized to above reactor pressure and then concentrated in solids content to a desired extent by centrifugal separation means before passing the concentrated slurry to the reaction zone. A clarified liquid stream withdrawn from the slurry concentration step is recirculated back to the mixing step to facilitate the pumping step.

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.
