For short-term parking, why is replacement necessary after the copper catalyst is depressurized?
How long do you mean by short-term parking?； In our company, short-term parking refers to periods of less than 12 hours ； No replacement is needed ； The purpose of replacement is to protect the catalyst ； Prevent temperature rise ； Or there are maintenance tasks to be carried out
Pressure relief and heat retention for short-term parking – great. . . . Relieving pressure prevents the reaction from continuing or side reactions from proceeding. What do you mean by \"replacing\" it? Are you trying to cause trouble?
For short-term parking within 24 hours, replacement is generally not required; it is sufficient for the temperature to return to normal levels and for the system to remain under positive pressure. However, in cases of long-term parking or when maintenance is needed, pressure must be released and the system replaced. Its function is to prevent air or other substances from entering the system and reacting with the catalyst (which is usually a copper-based catalyst that is reduced to elemental copper after the system is put into operation), thereby avoiding a sharp rise in the temperature of the catalyst bed or even the destruction of the catalyst.
