Reasons for catalyst pulverization
Thread Content
I would like to ask the experts: what are the reasons for the pulverization of medium-temperature catalysts?
The original poster failed to specify what kind of catalyst is involved, so only general statements can be made: 1. The main reason for catalyst fragmentation is the insufficient mechanical strength of the catalyst itself; fragmentation occurs due to changes in certain parameters during loading or operation. 2. In normal production, excessive variations in parameters, such as significant changes in reaction pressure or reaction temperature, can lead to the destruction of the catalyst. 3. The raw materials may contain substances that can cause the catalyst to break down; for example, most catalysts are sensitive to moisture, and when the raw materials contain a high amount of water, it can lead to the breakdown of the catalyst. 4. In the event of an accident in the unit, emergency pressure relief or cooling can easily lead to the crushing of the catalyst under such conditions.
Could you be more specific about the situation? What was the situation at that time?
Specific catalysts should be provided; different catalysts have different reasons for pulverization, but most cases are as described by Comrade 2#.
