1)Used in Claus reaction sulfur recovery unit petroleum refining, petrochemical and coal chemical industry.
2)Suitable for various concentrations of hydrogen sulfide and process conditions, can be whole bed loaded in any stage of Claus reactor or be used in combination with other type and function of catalysts by grading load.
3)Suitable for catalytic oxidation sulfur recovery process.
4)Promote hydrolysis rate of organic sulfur when used in the primary convertor and increase the total sulfur conversion when in secondary or teriary convertor.
1) AMC-LS-821 is TiO2-additive sulfur recovery catalysts with high Claus activity and organic sulfur hydrolysis activity, stable activity and long service life.
2) AMC-LS-901 is TiO2-based sulfur recovery catalyst with excellent sulfation resistance, higher Claus activity and organic sulfur hydrolysis activity, nearly approaching to thermodynamic equilibrium and not effected by “leaked O2”.
3) AMC-LS-981 is multifunctional Al2O3-Ti2O composite based sulfur recovery catalyst with good Claus activity, hydrolysis activity and O2 scavenging performance; excellent sulfation resistance; not sensitive to hydrocarbons content fluctuation in feed acid gas; good anti-carbon performance, high strength, stable in structure and activity, long service life.
