Abstract
Procedure for the catalytic reaction of gases with a high SO2 content in catalytic installations with several catalytic beds arranged one behind the other, where a partial stream of SO3-containing gases that have partially reacted is mixed with the SO2-containing gas before use in the first catalytic bed and the gases are cooled in an intermediate way between the catalytic beds, characterized in that at least a partial stream of the partial stream derived from gases that contain SO3 that have reacted partially is conducted, before the addition, through of an absorber, and the absorbed amount of SO3 is increased as a function of the increasing inactivation of the catalytic mass, so that the degree of transformation from SO2 to SO3 remains almost constant in the catalytic beds.
