Abstract: The third generation cyclemax technology of UOP was used in a 60kt/a CCR at Jingmen Refinery. In December 2017, the industrial application of on-line catalyst replacement technology was conducted on the device for the first time in China. It is certified that the technology of on-line catalyst change can create great economic benefits; after renewal of catalysts on line, the yields of H2 and C5+ liquid product increases and the H2 purity is higher. The timing of changing the catalyst is not subject to the restriction of scheduled maintenance time, and the device can complete the changing agent without stopping maintenance.

Key words: CCR, catalyst, on-line replacement
