NCT-12型常温COS水解催化剂的研制及应用

Research and application of NCT-12 type hydrolyst for COS under room temperature

介绍了NCT - 12型常温COS水解催化剂的实验室研制、工业扩试及工厂应用。在实验室考察了COS浓度及原料气空速对催化剂活性的影响 ,结果表明 ,在室温 ( 14～ 40℃ ) ,常压 ,COS入口浓度v(COS) 0 .15 % ,空速 10 0 0h-1的条件下 ,COS转化率 >95 %。工业扩试产品的性能符合质量指标 ,并略优于国内同类催化剂。

The laboratory research,industrial production and application of NCT-12 type hydrolyst for COS under room temperature were introduced. The influence of the concentration of COS and space velocity of feeding gas on the activity of the hydrolyst was examined in laboratory. The results showed that under conditions of room temperature (14～40℃), atmospheric pressure,concentration of COS input of 0.15%, and space velocity of 1000h -1 , the conversion of COS reached over 95%. The performances of industrial products accorded with the quality index,and were slightly better than the same kind catalysts inland. The commercial application was also good.
