    Abstract: A mono-stage device for generating gaseous sulphuric anhydride from melted sulphur, of the kind having two chambers, one inside the other and preferably concentric. The internal chamber contains spherical refractory material and has a duct feeding hot air into the bottom of the chamber. It opens at its upper end into the external chamber. Molten sulphur is fed into the upper end of the inner chamber and is burned to form SO.sub.2 which flows down in the external chamber containing catalytic material to form SO.sub.3 which is extracted through an outlet near the bottom of the external chamber.

    Abstract: A plurality of catalyzer beds are arranged in series in a reactor jacket. Associated with each catalyzer bed is a plurality of distributor pipes for supplying a fresh catalyst and a plurality of draining pipes for draining off the used catalyst. In one embodiment, the reactor jacket is rotatable and the plurality of distributor pipes are connected to an upper edge of the catalyzer bed while the plurality of draining pipes are connected to a lower edge of the catalyzer bed so that when the reactor jacket is rotated to a position that tilts the catalyzer beds the used catalyst will drain off. In another embodiment, the lower surface of the catalyzer beds are formed of two pivotable plates which pivot downwardly and away from each other to allow for the draining of the used catalyst. In still another embodiment of the invention, the heat exchangers are mounted below the catalyzer beds, and each catalyzer bed is provided with at least one supporting plate which divides the catalyzer bed into a plurality of sections parallel with the flow of the reactive gas through the catalyzer beds. Suction means may be used to supply catalyst to the catalyzer beds and to drain the used catalyst from the catalyzer beds.
