Abstract
The Bureau of Mines tested 48 materials for their ability to absorb h2s from hot simulated producer gas (1,000 deg to 1,500 deg f). The material found best from the standpoint of absorption capacity, durability, and amenability to regeneration was sintered pellets of 75 percent fly ash-25 percent fe2o3. The performance of this absorbent under simulated and actual conditions is described. The effect of absorbent composition, absorbent temperature, steam content of the gas, and tar vapors and dust in producer gas is discussed.
