CATALYSED HYPOCHLORITE DECOMPOSITION PROCESS

摘要

A process wherein a particulate catalyst, which is disposed in at least two serially connected beds, is contacted by a hy- pochlorite containing liquid to decompose the hypochlorite and evolve oxygen is improved by arranging that the liquid flows in a direction counter to that of the evolved oxygen in each of the beds. The efficiency with which the hypochlorite is decomposed is greater than when the liquid is in cocucrent or alternating co and counter current flow.
