Change the composition of the sulfur-resistant K8-11HR catalyst?
Thread Content
Does any senior colleague know the composition of the sulfur-resistant K8-11HR catalyst? What are its main properties?
Cobalt-molybdenum-based sulfur-resistant catalysts have a chemical composition of cobalt and molybdenum oxides supported on alumina; they become active only after the cobalt and molybdenum oxides are converted into sulfides (pre-sulfidation), and the feed gas must contain sulfides during the reaction. The applicable temperature range is 160–500°C, making it a wide-temperature conversion catalyst. It is characterized by sulfur and poison resistance, as well as a long service life.
