GP never implied the amount of ozone just the amount of aluminum oxide. All I know is catalysts can speed up reactions by orders of magnitude. CFCs actually created a hole in the ozone layer so its not like human activities haven't accidentally created problems before. Probably something that at least needs to be ruled out.

Correct. That's the same way I read that comment.

More fundamentally, chemical catalysts by definition are not consumed by the reactions they catalyze.

Think: a cheese grater. It doesn't react with the cheese, so a few ounces of grater could make hundreds of pounds of grilled cheese.

A hypothetical 300 tons of catalyst is not limited stoichiometrically to how much substrate it would affect.
