Abstract: There is provided a catalyst reaction apparatus comprising: a reactant inlet; a catalyst bed; a heat exchanger section; and a product outlet; wherein the heat exchanger section comprises a heat exchange pipe, through which heat exchange media can flow, extending between a pipe- inlet and a pipe-outlet as a jointless unit, at least a part of the heat exchange pipe being a coil. The invention seeks to provide a catalyst reaction apparatus, particularly a formaldehyde production apparatus, that is less susceptible to failures as a result of thermal stress; that is more easily repaired; and that may be more easily constructed.
