Abstract
Sulfur dioxide and sulfur trioxide may be removed from gases over a broad range of temperature and moisture conditions by utilizing a class of resinous adsorbents which retain their capacity at low moisture levels. Preferred embodiments are those resins which may be thermally regenerated to recover the sulfur.
