Desulfurization and low temperature regeneration of carbonaceous adsorbent
Patent
·
OSTI ID:7011071
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/sup 0/F to 1550/sup 0/F to partially oxidize the coal and transform it into an adsorbent suitable for use in the adsorber.
