预硫化耐硫变换催化剂在1.5×10^5 m^3/h合成气项目上的应用

Application of the presulfurized sulfur tolerant shift catalyst in the 1.5×10^5m^3/h synthesis gas project

昌邑凯特新材料有限公司开发的KC-103S型预硫化耐硫变换催化剂用于安阳盈德气体有限公司1.5×10^5 m^3/h合成气项目上。CO变换单元运行数据表明,该催化剂的强度稳定性、变换活性和活性稳定性等综合性能均能满足生产工艺需要,其在储存、运输和装填等过程中无需氮气保护,投用前无需配氢还原活化,用纯氮气升至起活温度即可导气,免硫化过程,能大大缩短开车时间,节约开车费用;降低开车过程床层超温的风险,操作更加安全方便;避免开车期间大量放空造成的资源浪费和环境污染。

The KC-103 S presulfurized sulfur tolerant shift catalyst(KC-103 S catalyst) developed by Changyi Kaite New Materials Corporation Ltd. has been being used for 1.5×10^5 m^3/h synthesis gas project of Anyang Yingde Gas Corporation Ltd.. The operation data of CO conversion unit show that the strength stability, conversion activity and activity stability of the catalyst can meet the needs of the production process. There is no need for nitrogen protection during the process of storage,transportation and loading of KC-103 S catalyst. Besides, the process gas can be directly introduced after the shift converter is heated to an initiation activity temperature by nitrogen before use, without sulfurization process and hydrogen reduction.The start-up time can be greatly shortened, and the start-up costs can be saved. The over-temperature risk of catalyst bed is reduced as far as possible and the start-up operation is safer and more convenient. Furthermore, a large resources waste and environmental pollution being produced from gas discharge will be avoided during the start-up.
