Claims

1. PROCESS FOR HYDROGENATING HYDROXCARBONS WHICH COMPRISES:

(A) FEEDING AN ADMIXTURE OF HYDROGEN AND A HEAVY GAS OIL FEED BOILING IN THE RANGE OF FROM ABOUT 650*F. TO ABOUT 1100*F. AND CONTAINING AT LEAST ABOUT 0.1% BY WEIGHT OF ORGANIC NITROGEN INTO A FIRST HYDROGENATION ZONE UPWARDLY THROUGH A MASS OF HYDROGENATION CATALYST CONTAINED THEREIN AT A RATE SUFFICIENT TO MAINTAIN THE CATALYST MASS IN A RANDOM MORTION EXPANDED STATE;

BUT BELOW THAT AT WHICH SUBSTANTIAL QUANTITIES OF CATALYST ARE RAISED TO AN UPPER PORTION OF SAID HYDROGENATION ZONE, SAID CATALYST MASS BEING MAINTAINED UNDER SUBSTANTIALLY ISOTHERMAL CONDITIONS;

(B) WITHDRAWING A FIRST HEATED EFFLUENT OF SAID HYDROGENATED OIL FROM AN UPPER PORTION OF SAID FIRST HYDROGENATION ZONE WHEREIN SAID HYDROGENATED OIL EFFLUENT CONTAINS A WEIGHT PROPORTION OF ORGANIC NITROGEN THAT IS BETWEEN ABOUT 10% AND ABOUT 80% OF THAT CONTAINED IN SAID HEAVY GAS OIL FEED;

(C) MIXING SAID HEATED EFFLUENT WITH ANAPHTHA HYDROCARBON BOILING IN THE RANGE OF FROM ABOUT 80%F. TO ABOUT 380*F. AND HAVING A BROMINE NUMBER OF AT LEAST ABOUT 50, SAID NAPHTHA BEING AT A LOWER TEMPERATURE THAN SAID HEATED EFFLUENT, AND AT LEAST A PORTION OF SAID NAPHTHA ADMIXED WITH THE EFFLUENT BEING IN THE LIQUID PHASE;
