摘要:

采用电子能谱仪，X光衍射仪，吸附仪等大型物化仪器和化学分析法。对几个厂家生产的C207催化剂在六个厂的工业使用情况进行了研究和剖析，结果表明：硫的存在严重影响催化剂的使用寿命，大量物化数据还表明，硫使催化剂中毒失活的原因是在催化剂表面一定深度内生成了ZnS等物质。

Abstract:

The investigation and anatomy of C207 catalyst produced by several fac tories and used in six plants have been made by several physical-chemical instru ments and chemical analytical methods.The results show that the sulfur has bad e ffects on the service
