摘要
加氢催化剂的预硫化是提高催化剂活性,优化加氢催化操作,获得理想经济效益的关键技术之一。为获得理想的预硫化效果,必须严格控制各阶段的反应条件。文章介绍了加氢催化剂预硫化的反应原理,探讨了在预硫化过程中影响催化剂预硫化效果的因素。预硫化操作中,温度是最敏感的因素之一。
Presulfuration of hydrogenation catalyst is one of the essential technologies. That can enhance the catalyst activity, optimize operation of hydrogenation catalysis, obtain ideal economic efficiency. In order to obtain the ideal presulfiding effect, must strictly control the conditions of various stages. Introduced the principal of presulfuration of hydrogenation catalyst,discussed the factors that has affected the effect of presulfuration in presulfiding process. In the presulfiding operation, the temperature is one of most sensitive factors.
