摘　　要：以疏水性纳米二氧化硅、去离子水、乙二醇和氧化钙为原料,考察了不同配比对干醇-水氧化钙形态的影响,制备出白砂糖状的干醇-水氧化钙催化剂。考察了活性组分质量、气体流量、醇-水体积比和催化剂使用寿命对COS催化水解的影响。结果发现,在室温、气体流量10 mL/min、催化剂质量2g条件下,干醇-水氧化钙(组成为:1.0g氧化钙、40mL乙二醇、40mL去离子水、19g疏水性纳米二氧化硅、搅拌时间10s)催化COS水解转化率在90%时,该催化剂的使用寿命为3.25h。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.
