Abstract: 1. A PROCESS FOR THE CONVERSION OF A RESIDUE-CONTAINING PETROLEUM FRACTION HAVING AN INITIAL BOILING POINT OF ABOUT 850*F. INTO LIGHTER PRODUCTS WHICH COMPRISES MAINTAINING IN A HYDRODESULFURIZATION ZONE A FIRST CATALYTIC ZONE BELOW AND A SECOND CATALYST ZONE A POINT OF ENTRY INTO SAID HYDRODESULFURIZATION ZONE, EACH OF SAID CATALYTIC ZONES CONTAINING A HYDRODESULFURIZATION CATALYST COMPRISING AN IRON GROUP METAL HYDROGENATION COMPONENT ON A REFRACTORY INORGANIC OXIDE SUPPORT OF SUBSTANTIALLY NO CRACKING ACTIVITY, THE CATALYST IN SAID FIRST CATALYTIC ZONE HAVING A SURFACE AREA OF FROM 250 TO 600 M.2/G. AND A POUR VOLUME OF FROM 0.6 TO 1.0 CC./G., INTRODUCING THE RESIDUE-CONTAINING PETROLEUM FRACTION THROUGH SAID POINT OF ENTRY INTO SAID HYDRODESULFURIZATION ZONE, MAINTAINING SAID FIRST AND SAID SECOND CATALYTIC ZONE AT A TEMPERATURE BETWEEN ABOUT 600 AND 775*F. AND A PRESSURE BETWEEN ABOUT 500 AND 5000 P.S.I.G., INTRODUCING HYDROGEN INTO SAID FIRST CATALYTIC ZONE TO FLOW UPWARDLY SERIALLY THROUGH SAID FIRST AND SAID CATALYST ZONES AND COUNTERCURRENT TO A PORTION OF SAID RESIDUE-CONTAINING PETROLEUM FRACTION AT A RATE OF AT LEAST 3000 S.C.F. PER BARREL TO RESIDUE-CONTAINING PETROLEUM FRACTION SUFFICIENT TO MAINTAIN LIQUID HYDROCARBON IN SAID SECOND CATALYTIC ZONE, SEPARATLEY RECOVERING PRODUCT FROM SAID FIRST AND SECOND CATALYTIC ZONE, CATALYTICALLY CRACKING THE OVERHEAD PRODUCT FROM SAID SECOND CATALYTIC ZONE AND SEPARATELY CATALYTICALLY CRACKING THE BOTTOMS FROM SAID FIRST CATALYTIC ZONE.

Abstract: Method of separating from hard water dissolved mineral hardness constituents whose solubility varies inversely with temperature, in which the water temperature is raised by direct, preferably cocurrent contact with a preheated stream of liquid hydrocarbon oil, to a temperature sufficient to precipitate hardness constituents but below the temperature at which the hot oil will extract water, and at a pressure sufficient to maintain the oil and water in liquid phase.

Abstract: Oil containing sulfur and asphalt is subjected to oxidation with organic peroxides or organic peracids at 75* - 200* F. The oxidant residue is removed by heating the oxidized product to about 150* - 450* F, and the heated oil is maintained at 300* 500* F to separate a lower asphalt layer and to separate the upper oil layer having a reduced sulfur content. The separated oil layer may undergo further desulfurization by thermal treatment at 500* - 900* F or catalytic hydrotreatment at 650* 900* F.
