After filling the converter with catalyst, it is still possible to use a large amount of air

The air comes from the air separation booster and can be considered dry air. I think it has no impact.
The unvulcanized new catalyst is fine; it is in an oxidized state to begin with.
The question is, what needs to be done for ventilation?
Isn’t it in constant contact with air during loading and before starting the vehicle?
As long as there is no sulfidation, air can be passed through without any issue. However, the sulfided catalyst must be kept away from air.
It definitely can’t be that way; we usually seal it immediately after installation and protect it with an inert gas. It is recommended to carry out the installation before driving, as this saves time and ensures safety. Is ventilating the air considered a form of displacement? Although it’s a new catalyst that hasn’t been sulfided, it is still very active; otherwise, there would be no need for a sealed packaging.
