In hydrocracking reactions, if sulfur and nitrogen are not removed thoroughly, does this cause temporary or permanent deactivation of the catalyst? Why?
I’m worried – why isn’t anyone answering?

Maybe it will help you. .
The reaction micropores in the catalyst become blocked, significantly reducing the reaction surface area; in other cases, toxic substances undergo irreversible chemical reactions with the catalyst, resulting in its permanent failure.
