| titleOfInvention | Stripping hydrocarbons from catalyst with combustion gases |
| abstract | Method of economical conversion of carbon-metallic oils into lighter products. Carbohydrate oils contain a material with a boiling point above 650 F which is characterized by a carbon pyrolysis residue of at least about 1 and a heavy metal content of at least about 4 parts per million nickel equivalents. This process comprises flowing the carbon-metallic oil with the particulate cracking catalyst through a progressive flow type reactor (2) having an elongated reaction chamber which is at least partially vertical or inclined, during a predetermined duration of steam retention in the riser of between 0.5 and 10 seconds approximately, at a temperature between 900 and 1400 F approximately and under an absolute pressure of approximately 10 to approximately 50 pounds per square inch, sufficient to cause a pass conversion of the order of about 50% to about 90% while producing coke in amounts of about 6 to 14% by weight calculated on the fresh feed, and depositing the coke on the catalyst quantities of the order of about 0.3 to 3% by weight. The catalyst uses coke feed from the hydrocarbon stream formed by the feed and the resulting cracked products vaporized is separated, the sorbed hydrocarbons are entrained (8) from the catalyst particles by contacting them in one or more beds fluidized with hot combustion gases. The entrained catalyst is regenerated in one or more regeneration beds (27) in one or more regeneration zones (21) by burning the coke on the spent catalyst with oxygen. The particles of the catalyst are retained in the regeneration zone (s) in contact with the combustion maintenance gas for an average total retention time in this or these zone (s) from approximately 5 to 30 minutes to reduce the level of carbon on the catalyst. up to about 0.25% by weight or less. The regenerated catalyst is |
