| titleOfInvention |
Hydrodesulfurization process for producing a heavy asphaltic fuel oil |
| 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. |
