Process for the production of gasoline and low molecular weight hydrocarbons
Abstract
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.
