Abstract: The replacement of CCR catalyst is an important process for refineries. Based on the data in two cycles of 1.0 MMt/a CCR unit of Jinling branch, SINOPEC, the economic benefits of the device under the replacement of a new catalyst in 1 cycle (4 years) and 2 cycle (8 years) were comprehensively analyzed from catalyst cost, fuel gas consumption, and product yield. The results show that the economic benefit of replacing new catalysts in one production cycle is 19.87 million Yuan /a higher than that in two production cycles. Replacing a new catalyst with one production cycle is more economical and can also reduce the number of unscheduled shutdown due to corrosion.

Key words: continuous catalytic reforming, catalyst, replacement cycles, economic benefit
