Pre-passivation process for a continuous reforming apparatus, and passivation process for a continuous reforming apparatus during the initial reaction

摘要

The present invention relates to a pre-passivation process for a continuous reforming apparatus prior to the reaction, or a passivation process for a continuous reforming apparatus during the initial reaction, comprising loading a reforming catalyst into the continuous reforming apparatus, starting the gas circulation and raising the temperature of a reactor, injecting sulfide into the gas at a reactor temperature ranging from 100-650° C., controlling the sulfur amount in the recycle gas within a range of 0.5-100×10⁻⁶ L/L so as to passivate the apparatus.
