Abstract: A PROCESS FOR THE PRODUCTION OF GASOLINE AND LOW MOLECULAR WEIGHT HYDROCARBONS FROM A GAS OIL FEED STOCK WHICH PROCESS COMPRISES A RISER TYPE CRACKING STEP PERFORMED ON A GAS OIL FEED AND THE CRACKING OF RECYCLE GASOLINE MATERIALS WHICH MAY TAKE PLACE IN EITHER A RISER TYPE REACTION ZONE OR A FLUIDIZED DENSE BED REACTION ZONE. THE RECYLCE GASOLINE IS CRACKED BY CONTACTING A PARTIALLY DEACTIVATED CRACKING CATALYST WHICH HAS PREVIOUSLY CONTACTED FRESH OIL FEED. THE GAS OIL IS CRACKED BY CONTACTING A FRESHLY REGENERATED CRACKING CATALYST. THE PROCESS OF RECYCLING GASOLINE ALLOWS A HIGHER PRODUCTION OF OLEFINIC C3 AND C4 HYDROCARBONS WHICH CAN BE CONVERTED TO HIGH OCTANE COMPONENTS AND THE INCREASED PRODUCTION OF C3 AND C4 SATURATES WHICH MAY BE VALUABLE IN THE PRODUCTION OF LPG FUEL.

Abstract: A process in which spent catalyst is regenerated with or without the complete combustion of CO in a regeneration zone comprising a first dense bed, a dilute phase transport riser and a second dense bed. Higher velocities and higher O2 concentrations employed within the regeneration zone result in shorter catalyst and gas residence time, reduced catalyst inventory, lower catalyst makeup rate, improved regeneration, and improved catalyst stability. The substantially complete combustion of CO eliminates CO pollution of the atmosphere without the need for a CO boiler and decreases feed preheat requirements.

Abstract: CATALYTIC CRACKING PROCESSES IN WHICH SHORT CATAYST-OIL CONTACT TIMES ARE DESIRED.

A FLUIDIZED CRACKING PROCESS IN WHICH A RISER TYPE REACTION ZONE EMPTIES INTO THE DILUTE PHASE PORTION OF A RECEPTION VESSEL. THE PROCESS CAN BE GENERALLY DESCRIBED AS ONE IN WHICH THE RISER REACTION ZONE IS SUBSTANTIALLY VERTICAL AND PASSES INTO THE RECEPTION ZONE WITH THE OUTLET OF THE RISER LOCATED WITHIN THE DILUTE PHASE PORTION OF THE RECEPTION VESSEL. ADJACENT TO THE RISER OUTLET IS A CYCLONE SEPARATION MEANS WHICH SEPARATES HYDROCARBONS AND SOLIDS PRESENT IN THE DILUTE PHASE. THE PROCESS IS GENERALLY APPLICABLE TO FLUIDIZED HYDROCARBON CONVERSION PROCESSES AND SPECIFICALLY ADAPTABLE FOR USE IN MODERN FLUIDIZED
