Determination of the chemical and hydrothermal stability of the Claus catalyst

Abstract

The hydrothermal and thermal stability used in the Claus process are important indicators in their workflow. In this work, the stability of two catalyst samples obtained from local raw materials was studied. The samples were processed with SO2 / O2 oxides and water vapor, and their properties were studied. As a result, SO2 adsorption reduced catalyst activation. The process is reductive; the recovery of catalyst activation by reducing SO2 in the system has been determined. The stability of sulfation of MgO / TiO2 catalyst in comparison with CaO / V2O5 samples was also determined.
