羰基硫水解催化剂的失活行为研究

Studies on deactivation of carbonyl sulfide hydrolysis catalyst

研究了羰基硫水解催化剂TGH 2在低浓度氧气存在下的失活行为 ,考察了温度、氧气浓度、羰基硫进口浓度对催化剂活性的影响 ,并用扫描电镜能谱联合装置对使用前后的催化剂进行分析 ,得到了较好的结果 。

The deactivation of carbonyl sulfide catalyst under low oxygen concentration has been studied. The effect of temperature, O 2 concentration, COS concentration on deactivation have been studied.SEM-EPMA has been also used to analyze the catalysts before used and have been used.
