What are the purposes and methods of cat passivation? Answer: Purpose: To prevent strong oxidation reactions that occur when Cat comes into contact with the atmosphere after being unloaded, which could lead to fires or equipment damage. Method: A fixed amount of air was introduced into the synthesis system, and a N2 positive pressure cycle was gradually passed through the Cat, causing the Cat to be oxidized to the oxide state (CuO).

Passivation is divided into pre-start passivation and shutdown passivation; pre-start passivation is used to prevent loss of control due to excessive activity of the new catalyst, while shutdown passivation is intended to prevent spontaneous oxidation
