Oxygen sulfide carbon COS gas sensorCarbon Oxygen Sulfide in the syngas of the COS gas sensor module module can be hydrolyzed with the water vapor in the gas on the catalyst to generate hydrogen sulfide, which is removed with desulfurizers such as activated carbon or zinc oxide. Hydrolysis catalysts generally use alumina as the main component. The oxygen and hydrogen sulfide in the gas will undergo oxidation reaction to generate sulfur dioxide and sulfur trioxide and interact with the catalyst to sulfate the catalyst and reduce the catalytic activityThe oxygen in the gas also oxidizes carbon sulfur oxide, and the resulting elemental sulfur coats the surface of the catalyst and inactivates the catalyst. Due to the above reasons, the current hydrolysis catalyst is not suitable for the primary desulfurization of crude gas, and is mostly used for the fine desulfurization of the hydrated alcohol process gas, and the hydrolysis temperature of carbon oxysulfide can be as low as 30 50, and the amount of residual sulfur in the gas after desulfurization is less than 01mg/m3。
