Application
Alumina
balls when used as bed toppings and supports will act as filters to remove
many impurities from the gas stream and help in uniform distribution of
the feed gas. Presence of Alumina Balls at the top and bottom of the
catalyst bed, keep the bed intact during pressure fluctuation. It can
withstand high thermal shocks and are unaffected by repeated emergency
shutdown and startups. The Alumina refractory bed supports are specially
useful as inert catalyst support in secondary reformers of ammonia
manufacturing plants and also in oil refineries and chemical process
industries.
