With the same gas many synthetic masses were used for the removal of organic S. A mixture of Fe₂O₃-Al₂O₃-brimstone and NaOH (Fe 10%, Fe₂O₃:Al₂O₃=1:1 and 1% NaOH) at 450° and a gas rate of 330 l. per hr. reduced the S to 0.19 gm. per 100 m.³ A 7:3 mixture of Luxmasse and diatomaceous earth with 30% NaOH at 350° and a gas rate of 330 l. per hr. reduced the S to 0.07 gm. per 100 m.³ A mixture of Fe₂O₃-bentonite-NaOH containing 10% Fe and 10% NaOH at 400° and a gas rate of 790 l. per hr. reduced the S to 0.16 gm. per 100 m.³ With the Fe₂O₃-Al₂O₃-diatomaceous earth-NaOH mass, the presence of CO₂ was harmful. Diatomaceous earth is the best carrier and materially increases the life of the purification mass.
