Abstract: Using hydrophobic nano-silicon dioxide, deionized water, ethylene glycol and calcium oxide as the raw material, dry glycol-water calcium oxide resembling confectioners' sugar was prepared by the high-speed mixing, and the effect of shape of weight percentage content on the shape of dry glycol-water calcium oxide was investigated. The effect of content of active constituents, volume of glycol-water, gas flow and service life of the catalyst on the COS hydrolysis transforming rate was investigated. Under the condition of room temperature, gas flow of 10 mL/min, dry glycol-water calcium oxide (the conditions of preparation: 1 g CaO, 40 mL deionized water, 40 mL ethylene glycol, 19 g hydrophobic nano-silicon dioxide, agitation time 10 s) of 2 g, COS hydrolysis transforming rate reached 90%, and service life of this catalyst was 3.25 hours.

Key words: Dry glycol-water, Carbonyl sulfide, Catalysis hydrolysis, Hydrophobic nano-silicon dioxide
