Currently, natural gas is an important component of the fuel and energy balance of many developed countries of the world. The development of large gas condensate fields is hindered by the high sulfur content of the gas, especially due to the tightening of environmental standards to ensure environmental protection, acidic gases require deep purification. An important aspect of the problem is also the need for deep cleaning of process gases. Due to the reduction or elimination of accordingly acidic components, the quality of the manufactured product is constantly increasing. Due to thermodynamic restrictions, the conversion depth of sulfur compounds does not reach 100% and, as a rule, 0.5-1.0% hydrogen sulfide is released along with the residual gases, after which there is a need for additional purification of the "residual" gases of Claus units. Development of the desulfurization process there is a need to improve the existing traditional installation technologies. Therefore, the issues of the synthesis of new catalysts and adsorbents are being actively studied, the issues of introducing an iron oxide catalyst as an affordable and inexpensive material for sulfur dioxide purification processes are being considered.  In the course of testing iron-containing catalysts for H₂S oxidation, the nature and morphology of the interaction of elements were determined.
