Abstract
A gas desulfurization process is disclosed wherein a particulate, partially oxidized coal is used as an adsorbent for gaseous sulfur oxides and is regenerated by contact with a low temperature recycled stream of its own desorbed off-gas containing at least 40% steam and 15% SO.sub.2. A bleed stream of the desorbed off-gas may be reacted with coal at 1150.degree. F. to 1550.degree. F. to partially oxidize the coal and transform it into an adsorbent suitable for use in the adsorber.
