Literature Abstracts

Researches were undertaken to find a satisfactory method of S removal, with known or new materials, from a gas to be used further for the synthesis of benzine, its S content to be less than 0.2 gm. S per 100 m.³ City gas, with a total S content of 24.0 gm. S per 100 m.³ of which 22.6 gm. S is organic, was freed of CO₂ and H₂S and as such used over adsorbent materials, dry purificants and H₂S extraction materials at room temperature. As adsorbent materials were used active C, SiO₂ gel, Japanese acidic-earths and Adosol. Active C was found the most efficient but not active enough to produce a highly purified gas. As dry purificants Fe₂O₃ on a pumice support and Luxmasse were used, as H₂S scrubbing materials Thylox solution and (C₂H₅)₃N to which Fe₂O₃ was added were used. 80% S removal was obtained with the dry purificants. Thylox failed to extract the organic S, while with (C₂H₅)₃N, 67.7% S removal was obtained; it was further improved by addition of Fe₂O₃.
