Abstract: The application of reactor cross-line for capacity expansion of a continuous catalytic reforming unit was introduced. During revamping, the bottlenecks such as catalyst attachment on the reactor wall, insufficient heat load of heating furnace for the reactor and insufficient coke removing capacity of the regenerator were encountered. Theoretical calculation and comparison of operation data before and after expansion proved that the addition of reactor cross-line could effectively avoid the phenomenon of catalyst attachment and reduce the heating load of downstream furnace, indicating that the method is a new technical solution for the capacity expansion of CCR unit.

Key words: continuous catalytic reforming, capacity expansion, cross line, adherence
