Two stage destructive hydrogenation process for the production of gasoline from hydrocarbon oils

Claim 1

A PROCESS FOR THE PRODUCTION OF GASOLINE FROM MINERAL OILS AND SHALE OILS BY DESTRUCTIVE HYDROGENATION IN TWO STAGES WHICH COMPRISES LEADING THE INITIAL MATERIALS IN THE LIQUID PHASE THROUGH A REACTION ZONE AT A TEMPERATURE OF 450* C. TO 550* C. TOGETHER WITH 1 TO 10 CUBIC METRES OF HYDROGEN PER KILOGRAM OF MATERIALS PER HOUR, UNDER A PRESSURE OF 200 TO 800 ATMOSPHERES AND AT A RATE OF 0.5 TO 2.5 KILOGRAMS PER LITRE OF REACTION SPACE PER HOUR, ADJUSTING THE THROUGHPUT AND TEMPERATURE SO THAT MORE THAN 30% OF MIDDLE OIL BOILING IN THE RANGE OF 180* C. TO 350* C. IS FORMED; AND LEADING THE RESULTING PRODUCT CONTAINING GASOLINE, HEAVY OIL AND MIDDLE OIL, WITHOUT RETURING IT TO THE SAID REACTION ZONE, INTO A SECOND REACTION ZONE TOGETHER WITH HYDROGEN IN AN AMOUNT OF FROM ABOUT 1 TO 5 CUBIC METRES PER KILOGRAM OF OIL PER HOUR UNDER A PRESSURE OF 200-800 ATMOSPHERES, AT A TEMPERATURE OF 400* C. TO 550* C. AND AT A RATE OF 0.3 TO 1.5 KILOGRAMS PER LITRE OF CATALYST VOLUME PER HOUR OVER AN ACTIVATED ACID CARRIER SUBSTANCE FROM THE GROUP CONSISTING OF ACID-TREATED NATURAL SUBSTANCES CONTAINING SILICIC ACID, ACID SYNTHETIC SILICATES, AND ACTIVATED ACID ALUMINAS WHICH IS PROVIDED WITH A SMALL AMOUNT OF A COMPOUND OF A METAL OF THE GROUP CONSISTING OF MOLYBDENUM AND TUNGSTEN, THE REACTION IN SAID SECOND ZONE BEING CARRIED OUT IN THE GASEOUS STATE.
