俄罗斯炼厂试验了一段脱除Ｈ_２Ｓ过程格罗兹石油化工厂进行了酸气直接氧化制硫的中间试验，所试的几种催化剂以ＭｇＣｒ２Ｏ４／ｒ－ＡＬ２Ｏ３最好，一段Ｈ２Ｓ转化率可达９９％，生成硫的选择性可达９７％～９９％。（王开岳摘自ＯＧＪ，１９９４，９２（１０）：８１?..
The Russian refinery experimented with an intermediate test for the direct oxidation of sour gas to the gas at the Grozsch Petrochemical Plant for the de-H 2 S process. The best catalysts were MgCr 2 O 4 / r-Al 2 O 3 and the conversion to H2S was 99 %, The selectivity of generating sulfur up to 97% to 99%. (Wang Kaiyue from OGJ, 1994, 92 (10): 81?
