Process for regeneration of sulfuric acid laden activated carbon
Abstract
Abstract A process for regenerating a sulfuric acid laden activated carbonaceous adsorbent by contacting the activated carbonaceous adsorbent at a temperature below about 350* F. with hydrogen sulfide in an amount of at least 3:1 mole ratio of hydrogen sulfide to adsorbed sulfuric acid to reduce the adsorbed sulfuric acid to elemental sulfur which remains adsorbed on the adsorbent, steam stripping at least 1 mole of elemental sulfur per 3 moles of hydrogen sulfide from the activated carbonaceous adsorbent and recovering the steam stripped elemental sulfur. When it is desired to strip less than all of the elemental sulfur from the activated carbonaceous adsorbent the remaining sulfur may be reduced with hydrogen to produce hydrogen sulfide for use in reducing the adsorbed sulfuric acid.
