Upgrading of crude petroleum oil

Claim 1

A METHOD OF PRODUCING A SUBSTANTIAL QUANTITY OF OIL BOILING IN THE RANGE OF FROM ABOUT 400*-1000*F. FROM A CRUDE METALS-CONTAINING OIL HAVING AN API GRAVITY OF THEREOF, AGITATING THE DISTILLANT BY INTRODUCING STEAM SLURRY WITH A HYDROGEN-CONTAINING GAS IN THE PRESENCE OF A PARTIALLY DEACTIVATED HYDROGENATION CATALYST IN A FIRST REACTOR ZONE OPERATED UNDER DESULFURIZATIN AND MILD HYDROGENATION CONDITIONS OF 400-2000 P.S.I.G. AND 700*760*F. TO FORM A QUANTITY OF LOWER BOILING RANGE OILS, REMOVING PRODUCTS BOILING LOWER THAN ABOUT 900*-1000* F., CONTACTING THE REMAINING HEAVING PORTION IN A SLURRY IN A SECOND REACTION ZONE WITH A HYDROGEN-CONTAINING GAS IN THE PRESENCE OF A FRESHLY REGENERATED HYDROGENATION CATALYST OPERATED UNDER DESTRUCTIVE HYDROGENATION CONDITIONS OF 400-2000 P.S.I.G. AND 800*-900*F., WHEREBY A SUBSTANTIAL QUANTITY OF ADDITIONAL LOWER BOILING OILS IS FORMED, MAINTAINING THE TOTAL AMOUNT OF HYDROGEN CONSUMED IN BOTH ZONES BELOW 400 S.C.F./BBL., PASSING CATALYST FROM THE SECOND REACTION ZONE TO THE FIRST REACTION ZONE, FROM THE FIRST REACTION ZONE TO REGENERATION WITH AN OXYGEN-CONTAINING GAS, AND FROM REGENERATION BACK TO THE SECOND REACTION ZONE AND RECOVERING A TOTAL PRODUCT FROM THE PROCESS WHICH INCLUDES A SUBSTANTIAL AMOUNT OF GAS OIL.

Claim 2

A METHOD OF PRODUCING A SUBSTANTIAL QUANTITY OF OIL BOILING IN THE RANGE OF FROM ABOUT 400*-1000*F. FROM A CRUDE METALS-CONTAINING OIL HAVING AN API GRAVITY OF THEREOF, AGITATING THE DISTILLANT BY INTRODUCING STEAM SLURRY WITH A HYDROGEN-CONTAINING GAS IN THE PRESENCE OF A PARTIALLY DEACTIVATED HYDROGENATION CATALYST IN A FIRST REACTOR ZONE OPERATED UNDER DESULFURIZATIN AND MILD HYDROGENATION CONDITIONS OF 400-2000 P.S.I.G. AND 700*760*F. TO FORM A QUANTITY OF LOWER BOILING RANGE OILS, REMOVING PRODUCTS BOILING LOWER THAN ABOUT 900*-1000* F., CONTACTING THE REMAINING HEAVING PORTION IN A SLURRY IN A SECOND REACTION ZONE WITH A HYDROGEN-CONTAINING GAS IN THE PRESENCE OF A FRESHLY REGENERATED HYDROGENATION CATALYST OPERATED UNDER DESTRUCTIVE HYDROGENATION CONDITIONS OF 400-2000 P.S.I.G. AND 800*-900*F., WHEREBY A SUBSTANTIAL QUANTITY OF ADDITIONAL LOWER BOILING OILS IS FORMED, MAINTAINING THE TOTAL AMOUNT OF HYDROGEN CONSUMED IN BOTH ZONES BELOW 400 S.C.F./BBL., PASSING CATALYST FROM THE SECOND REACTION ZONE TO THE FIRST REACTION ZONE, FROM THE FIRST REACTION ZONE TO REGENERATION WITH AN OXYGEN-CONTAINING GAS, AND FROM REGENERATION BACK TO THE SECOND REACTION ZONE AND RECOVERING A TOTAL PRODUCT FROM THE PROCESS WHICH INCLUDES A SUBSTANTIAL AMOUNT OF GAS OIL.
