In contrast to the previously tested city gas, water gas containing 11.7 gm. total S per 100 m.³ and 11.0 gm. organic S per 100 m.³, from which the H₂S had been removed by treatment with Thylox solution (1.5% Na₂CO₃; 0.7% As₂O₃), could not be freed sufficiently from S compounds to be suitable for use in the benzine synthesis, which requires less than 0.2% S per 100 m.³, by treatment at 250° with Luxmasse, Luxmasse+10% NaOH, Luxmasse+Na₂CO₃ (2:1), ignited Fe₂O₃-Al₂O₃-diatomaceous earth-NaOH (1:1:2 with 10% NaOH), ignited Fe₂O₃-Al₂O₃-pumice-NaOH (1:1:2 with 10% NaOH, Luxmasse-diatomaceous earth-NaOH (7:3 with 30% NaOH) or ignited Fe₂O₃-bentonite (containing 10% Fe), with a total of 150 l. of gas, a gas velocity of 30 l. per hr., a space velocity of 400, and a 25 cm. layer of treating agent. Total S contents of the treated gas samples (gm. S per 100 m.³) were 1.72, 1.88, 1.90, 1.30, 9.30, 3.68, and 4.05, respectively. 10% of an equimolecular mixture of Fe and Cu on pumice and of Ni on pumice lowered the S content of the water gas to 0.43 and 0.85 gm. S per 100 m.³, respectively. Temperatures above 250° resulted in C formation from the CO of the water gas; thus at 350°, although the S content of the gas was reduced to less than 0.07 gm. per 100 m.³, the Luxmasse+10% NaOH contained much C from energetic decomposition of CO.
