How is the pre-sulfided catalyst used in various units? How long is the current longest usage cycle? Will the activity of the presulfided catalyst be affected?
At present, the longest operating cycle is the three years that Changyi Kate has been in use at a 400,000-ton synthetic ammonia plant in Xinjiang; comparisons based on actual operation show that the use of presulfided catalysts yields very good results! The activity was not affected!
