Does the catalyst need to be preheated before use?

I’m just asking gently. Does the catalyst need to be preheated before use?
Preheating is not possible; the temperature can only be increased gradually at a certain rate.
What a reaction! Generally, a reaction requires certain conditions to occur; without them, no reaction takes place! In the case of an exothermic reaction, preheating is generally not done in the initial stage to prevent the reaction from becoming too intense and difficult to control. If there is no response, it still needs to be preheated.
Preheating and temperature elevation for reduction are required, followed by introducing air at a temperature above the desired level
To change the catalyst, it is necessary to raise the temperature to the operating temperature before proceeding to the next step
Whatever the catalyst is, it has an activation temperature; as long as that temperature is reached, it will work

Catalysts generally have specific usage requirements; just follow those requirements. It usually requires heating for preheating.
