Method for passivating cracking catalyst |
| 摘要 |
A method and apparatus for passivating the adverse catalytic effects of metal contaminated hydrocarbon feedstocks is described. The method is directed at the use of control means to regulate the residence time of the catalyst in the passivation zone and to regulate the reducing gas flow rate to the passivation zone.
