Abstract
1517438 Removal of nitrogen oxides and sulphur dioxide MONSANTO CO 30 Sept 1976 [1 Oct 1975] 40554/76 Heading C1A Nitrogen oxides and sulphur dioxide are removed from a gaseous mixture by contacting the gaseous mixture with a solid reagent comprising calcium oxide, magnesium oxide or a mixture thereof at a temperature above 650‹C in the presence of an amount of reducing gas comprising carbon monoxide, hydrogen or a mixture thereof sufficient to reduce all of the sulphur dioxide, nitrogen oxides and any oxygen present in the mixture.
