Carbon deposition treatment of conversion catalysts
Thread Content
"The conversion catalyst has suffered severe carbon deposition; from the perspectives of chemical equilibrium and safety, it can be treated by introducing an appropriate amount of air into the steam. That’s what the information says. What I want to ask is, is it safe to add an appropriate amount of air?
Catalyst carbon deposition, and the introduction of air leads to a burning process; an oxygen-rich processing environment is definitely unsafe (it can easily cause overheating and damage to equipment, etc.)； This process is also the catalyst deactivation process that occurs during hydrogen production shutdown; by controlling the proportion of air introduced, the carbon burning effect should be quite noticeable. The conversion and intermediate transformation catalyst deactivation processes also occur simultaneously during coking.
