What is the temperature change of the reformer before and after startup?
Thread Content
The temperature of our reformer changes greatly. The comparison between normal production after shutdown and normal production before shutdown is as follows: Normal production after shutdown and before shutdown Upper layer: 60609: 1035, 1090 Middle layer: 60608: 960 930 60607: 955 900 Exit: 60611: 951 945 60612: 939 944 May I ask if we used coke oven gas and steam for 24 hours? Does this have anything to do with it? Thank you!
There is a relationship. Affects the activity of the catalyst. Especially the impact is greater when the temperature is above 500 degrees.
This is because the conversion catalyst easily forms crystallized stones at 400-500 degrees.
