Purification of water gas from hydrogen sulfide. [Use of bog iron ore; effects of thickness of absorption layer, speed of gas, wetting of mass by an aqueous solution of NH/sub 4/OH, presence of NH/sub 4/Cl, (NH/sub 4/)/sub 2/CO/sub 3/, CaO, KOH, NH/sub 4/OH, and Na/sub 2/CO/sub 3/; purification by activated C is effective]
Removal of sulfur dioxide gas by manganese oxy-hydroxide. [MnO(OH) is sprayed as mixture with Mn sulfate (wet process) into gas or used as granules in bed (dry method); S dioxide removal is 97. 2% by wet and over 99% by dry method; convenient and economical]
Absorbing sulfur dioxide from industrial waste gases. [Presence of small amounts of Na, K, or ammonium hydroxides increases absorption of sulfur dioxide to 80-90% in comparison with 70-80% with zinc hydroxide]
