| 摘 要： | 采用一套玻璃真空系统，对COS、H2S、O2各自的吸附行为进行了研究，通过红外谱图发现COS是解离吸附，由H2S＋O2的共吸附与H2S＋O2＋COS的共吸附结果可以看出，只有H2S与O2共存时，才会导致催化剂的失活，且导致COS水解催化剂失活的主要原因是单质硫和微量的硫酸盐沉积于催化剂的表面，温度越高，失活越严重，红外光谱得出的结果与微反得出的结果一致，并提出了失活机理。

| Abstract: | The adsorptions of COS, H 2S and O 2 were investigated result by FTIR equipped with a set of glass vacuum apparatus It was found that the adsorption of COS on TGH catalyst could be a dissociative adsorption The FTIR results of COS +H 2S +O 2 co adsorption on TGH catalyst show that catalyst deactivation can occur when H 2S and O 2 existed The reaction temperature has a great influence on TGH catalyst deactivation In other words, high reaction temperature could accelerate TGH poisoning The FTIR is in agreement with that of micro reaction system and deactivation mechanism was put forward for COS hydrolysis |
