Thermally insulated reactor.

摘要

A generally cylindrical vessel (3) encloses a bed (17) of active material for treating a gas flowing from inlet (11) to outlet (13), the bed being located within a peripheral sleeve (25) spaced from the vessel side wall (5) by an annular gap (27), which is closed at one end by a wall (43) and insulates the bed thermally from wall (5).
