Discussion on the Use of Methanol Synthesis Catalysts
Thread Content
Regarding the factors affecting the use of methanol synthesis catalysts, such as the decline in the catalyst’s catalytic activity and the impact of catalyst activity on the one-pass conversion rate, we welcome active discussions from everyone
High temperatures have no effect. The occurrence of pulverization can be attributed to two factors: 1) There is a problem with the strength of the catalyst itself, which can be detected during factory testing; 2) Operational issues. High temperatures can cause the catalyst to sinter, while pulverization mainly results from too rapid pressure changes, an excessive space velocity (large pressure difference), large temperature fluctuations, or water entering the catalyst layer. Generally, these are the main factors. The most likely cause is an excessive rate of pressure increase or decrease; high internal pressure combined with too rapid pressure release can lead to the breakdown of the material, just like a balloon – when the internal pressure is high and the external pressure is low, the balloon bursts. A rapid increase in pressure may result in crushing of the material
