Abstract
SO.sub.2 -containing gas is made to contact a carbon-containing material to reduce the gas to a gas mixture containing sulfur and also containing H.sub.2 S and SO.sub.2 in a volume ratio of 2:1. The sulfur is then removed by condensation and the remaining gas mixture subjected to a Claus-process treatment to obtain additional sulfur from it.
