(57) ABSTRACT

A reactor apparatus including a support element rotatable about an axis (1) and having a surface (2) generally centred on the axis. The surface (2) is adapted for outWard How of a thin ?lm of a liquid phase reactant thereacross When supplied thereto as the surface (2) is rotated. The reactor apparatusisfurtherprovidedWithaplateorshroud(10)that covers or is coextensive With the surface (2) and de?nes a gap (14) between the surface and an underside of the plate

or shroud (10) so as to alloW a gaseous phase ?oW through the gap (14) and over the thin ?lm of the liquid phase reactant. By constraining the gaseous phase ?oW over the liquidphasecomponent,especiallyWhenthegaseousphase How is countercurrent to the liquid phase ?oW, excellent mass transfer between the tWo phases can be achieved.
