Abstract
Procedure for the reduction of sulfur dioxide, characterized in that it comprises contacting said sulfur dioxide with a calcium aluminate catalyst at a temperature of the order of 1500ºF to 2600ºF (approx., 815 - 1425ºC), in the presence of a reducing agent chosen from the group consisting of at least one member of the group consisting of hydrogen and carbon monoxide and a gaseous hydrocarbon.
