Oxygen Scavenging Sulfur Recovery Catalyst HYS-971
Characters
HYS-971 is kind of sulfur recovery catalyst with dual functions of high Claus activity and O2 scavenging. In the same unit, the total sulfur conversion can be increased by 1.7% when it is combined with Al2O3 based catalyst. It is an innovation in China and it stands at the world advanced level
Dual functions of high Claus activity and O2 scavenging.
High activity and stability.
Preventing or lessening Al2O3 based catalyst from being sulfated due to “leaked O2” in process gas to prolong the service life of the catalyst.
Applications and operating conditions
Suitable for Claus sulfur recovery in petrochemical and coal chemical industry, it can be used in any Claus reactor loaded full bed or in combination with other catalysts of different types or functions. It is loaded in the upper section of the reactor bed with at least 1/3 of the total volume to prevent or lessen the sulfation of Al2O3 based catalyst by “leaked O2” in process gas, which will result in long service life of the catalyst
