Abstract

PURPOSE: To remove essentially all sulfur components consisting of H2S, CS2 and COS from a gas mixture composed mainly of CO, etc. and containing sulfur compounds as impurities, by passing the gas mixture through a packed layer composed of calcium oxide and barium oxide at a specific temperature.
CONSTITUTION: A gas mixture containing ≥50vol% (pref. ≥90vol%) of CO or CO and H2 and small amounts of H2S, COS and CS2 as impurities, and free from SO2 and SO3, is passed through a packed column containing CaO and/or BaO layers at 300W700°C (esp. 400W650°C) at a space velocity of e.g. 10W1,000hr-1 to effect the desulfurization. The CaO and/or baO are usually formed to pellets of 1W5mm in diameter, and charged in a packed layer using a perforated plate or a wire mesh as a substrate. The content of the impurity components in the gas mixture is usually, 1W5,000ppm of H2S, 1W1,000ppm of CS2 and 1W2,000ppm of COS.
