What should be noted when using metal passivators?

Reply #22019-07-10

The temperature before injecting the passivator should preferably be below its decomposition temperature; otherwise, the passivation effect will be reduced or even non-existent. The effectiveness of this process is related to the surface area of the catalyst – the larger the surface area, the worse the effect. The passivation effect is also influenced by temperature: at temperatures below 500 degrees Celsius, the effect is poor. Additionally, sufficient mixing time is required before addition, so that the passivator can mix thoroughly with the raw materials. Good atomization effects are also necessary, as well as proper contact between the raw materials and the catalyst
