Abstract: A process that removes sulfur dioxide from a gas containing sulfur dioxide treats the gas at an elevated temperature in the presence of a reducing gas and a catalyst for the reaction between the reducing gas and sulfur dioxide. When gas containing sulfur dioxide, such as flue gas and smelter gas, contains oxygen gas above a very low concentration, it is necessary to modify the process either by the use of additional reducing gas or by a pretreatment of the gas so as to decrease selectively the oxygen gas content or by the use of both modifications.
