A catch tank is designed to collect old oil that would normally be fed back into the inlet manifold to be burned.
The breather pipe (usually on the rocker cover) should feed into the catch tank, and the return from the tank should feed back to the inlet manifold. Oil vapour will then be combusted as normal but any dirty oil spray will catch in the tank. Other option is to plug the inlet and have the return from the catch tank pointed down under the car somewhere to vent the fumes.
Just a way of running a slightly cleaner burn. We've all seen an oily inlet mani, right?
