Why is sodium added to the catalyst?

Is it used to adjust pH?
Ah! ! ! Adjust the acidity and alkalinity of the catalyst.
It wasn’t added manually; it appeared during the catalyst manufacturing process.
What does that mean? ? ? I only know that its components are like this. I don’t know what the effect of adding na is
I think the answer on the second floor is correct; it’s supposed to be used for adjusting pH levels
It should provide acidity at the acidic center
What does that mean? . Acidic center? ?
Bicarbonate can provide hydrogen ions
Keeping the catalyst in a slightly acidic environment makes it easier to store, right?
The original poster should learn about acid catalysts~~ The activity of such catalysts stems from their acidic sites, which are known as acid centers~~
