| titleOfInvention | Magnetic separation of high activity catalyst from low activity catalyst |
| abstract | A B S T R A C T A process for economically converting carbo-metallic oils to lighter products. The carbo-metallic oils contain 650° F plus material which is characterized by a carbon residue on pyrolysis of at least about 1 and a Nickel Equivalent of heavy metals content of at least about 4 parts per million. This process comprises flowing the carbo-metallic oil together with particulate cracking catalyst through a progressive flow type reactor having an elongated reaction chamber, which is at least in part vertical or inclined, for a predetermined vapor riser residence time in the range of about 0.5 to about 10 seconds, at a temperature of about 900 to about 1400° F, and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 50% to about 90% while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and laying down coke on the catalyst in amounts in the range of about 0.3 to about 3% by weight. The spent, coke-laden catalyst is separated from the stream of hydrocarbons formed by vaporized feed and resultant cracking products and regenerated in one or more regeneration beds in one or more regeneration zones by burning the coke on the spent catalyst with oxygen. The regenerated catalyst is recycled to the reactor and contacted with fresh carbo-metallic oil. A portion of the catalyst is withdrawn from the cycle, passed through a magnetic field to separate the mass of catalyst into high activity catalyst and low activity catalyst, returning the high activity catalyst to the cycle and disposing of the low activity catalyst. |
