Abstract: ASPHALT-CONTAINING OILS ARE HYDRODESULFURIZED TO BELOW A REFRACTORY SULFUR LEVEL WITHOUT EXCESSIVELY CONVERTING THE ASPHALT PRESENT BY EMPLOYING A TWO-STAGE HYDRODESULFURIZATION SYSTEM WITH INTERSTAGE HYDROGEN SULFIDE AND LIGHT OIL REMOVAL, WHEREIN THE AVERAGE HYDROGEN PARTIAL PRESSURE IN EACH HYDROESULFURIZATION STAGE IS MAINTAINED SUFFICIENTLY HIGH THAT THE AVERAGE REACTION RATE CONSTANT IS IMPROVED BY A TWO-STAGE OPERATION, BUT SUFFICIENTLY LOW SO THAT NOT LESS THAN ABOUT 50 PERCENT BY WEIGHT OF THE FEED IS RECOVERED AS A PRODUCT BOILING ABOVE THE I.B.P. OF THE FEED.

Abstract: ASPHALT-CONTAINING OILS ARE HYDRODESULFURIZED WITHOUT EXCESSIVELY CONVERTING THE ASPHALTENES AND RESINS PRESENT BY CONTROLLING THE EXTENT OF DESULFURIZATION OF THE ASPHALTIC PORTION OF THE OIL IN RESPONSE TO THE QUANTITY OF AROMATICS PRESENT. AS THE ASPHALTIC OIL PASSES THROUGH A HYDRODESULFURIZATION ZONE, THE AROMATIC CONTENT OF THE OIL INCREASES DUE TO IN SITU PRODCTION OF AROMATICS. THE OIL IS WITH-
DRAWN FROM THE HYDRODESULFURIZATION ZONE WHEN THE AROMATIC CONTENT NO LONGER INCREASES.-

Abstract: ASPHALT-CONTAINING OILS ARE DESULFURIZED TO REMOVE REFRACTORY, ASPHALTIC SULFUR WITHOUT EXCESSIVELY CONVERTING THE ASPHALTENES AND RESINS PRESENT IN A HYDRODESULFURIZATION PROCESS, WHEREIN THE RATIO OF AROMATICS TO SATURATES IS
INCREASED TO PROVIDE THE PROPER SOLVATION FOR THE ASPHALTENES AND RESINS AND THEREBY INCREASE THEIR DESULFURIZATION RATE.-

Abstract: ASPHALT-CONTAINING OILS ARE HYDRODESULFURIZED TO BELOW A REFRACTORY SULFUR LEVEL WITHOUT EXCESSIVELY CONVERTING THE ASPHALT PRESENT BY EMPLOYING A TWO-STAGE HYDRODESULFURIZATION PROCESS WITH INTERSTAGE HYDROGEN SULFIDE AND LIGHT OIL REMOVAL, WHEREIN THE QUANTITY OF AROMATICS AND SATURATES PRESENT IS CONTROLLED TO PROVIDE THE PROPER SOLVATION OF ASPHALTENES AND RESINS SO AS TO PERMIT REFRACTOR SULFUR REMOVAL THEREFROM.

Abstract: ASPHALT-CONTAINING OILS ARE HYDRODESULFURIZED TO BELOW A REFRACTORY, ONE PERCENT SULFUR LEVEL WITHOUT EXCESSIVELY CONVERTING THE ASPHALTENES AND RESINS PRESENT BY EMPLOYING A TWO-STAGE HYDRODESULFURIZATION PROCESS WITH INTERSTAGE HYDROGEN SULFIDE AND LIGH OIL REMOVAL, WHEREIN THE SULFUR-CONTAINING ASPHALTENES AND RESINS PRESENT IN THE ASPHALTIC OIL ARE SULUBILIZED AND THEREBY RENDERED MORE EASILY DESULFURIZED BY AN AROMATIC-CONTAINING LIGHT OIL THAT IS BOTH PRODUCED IN SITU IN THE HYDRODESULFURIZATION ZONES AND IS OBTAINED FROM FEED AND PRODUCT STREAMS WITHIN THE SYSTEM.

CPC classification number: C10G45/02 , C10G2300/107
Abstract: A PROCESS FOR HYDRODESULFURIZING A CRUDE OIL OR A RESIDUAL OIL COMPRISES PASSING THE OIL OVER A HYDRODESULFURIZATION CATALYST TO ACHIEVE A DESIRED DEGREE OF SULFUR IN THE EFFLUENT PRODUCT. A SUBSTANTIALLY CONSTANT TEMPERATURE WITH VARYING EFFLUENT SULFUR LEVEL IS MAINTAINED
DURING THE PROCESS SUCH THAT MORE THAN THE DESIRED DEGREE OF SULFUR REMOVAL IS ACHIEVED DURING AT LEAST A PORTION OF THE DURATION OF THE PROCESS.
