摘要
使用载硫型催化剂,开工现场不需要准备硫化剂,不用注硫泵等注硫设施,载硫型催化剂装填完毕后,只需按要求活化即可,缩短了开工周期,降低了安全风险。载硫型催化剂堆密度高于氧化态催化剂,保证了反应深度。目前各催化剂活性高,效果明显,产品质量合格,满足生产需要。同时利用原料中烯烃含量提高催化剂活化时床层温度有一定效果,为同类生产装置遇到类似问题提供了参考。
With sulfur-bearing catalyst,vulcanizing agent and sulfur injection facilities are not needed in the startup of hydrogen production unit.After filling sulfur-bearing catalyst,the catalyst only needs to be activated as required,thus shortening the construction period and reducing the safety risk.The density of sulfur-bearing catalyst is higher than that of oxidized catalyst,which ensures the reaction depth.At present,the activity of catalyst is high,the effect is obvious,the product quality is qualified and meets the production needs.At the same time,using the olefin content in the raw material to increase the bed temperature when the catalyst is activated has a certain effect,which provides reference for similar production equipment to encounter similar problems.
