The influence of iron compounds in the sulfuric acid catalyst on the SO2 oxidation process

The catalytic oxidation process of SO2 to SO3 is the main stage of sulfuric (VI) acid production. The process run could be disordered by reason of the increased inactivation of sulfuric acid catalyst during SO2 oxidation process. This paper includes the influence study of the iron quantity and forms, which is introduced into the catalyst active phase, on the reaction rate of the SO2 oxidation process.
