Abstract
An apparatus for the direct fluorination of solid particles of polymeric resins capable of being fluorinated in which the solid particles are in contact with the gaseous phase of fluorine/dense carrier fluid in a tubular reactor with an internal mechanical device comprising a rotatable shaft with screw flight, multiblade or wire brush that mechanically fluidizes the solid phase. The design of the internal mechanical device is a function of the diameter and length of the tubular reactor and the reaction time and other physical properties of the solid particles of polymeric resins. The internal mechanical device prevents agglomeration of the solid particles and promotes uniform contact with the gaseous phase by inducing mobility to the solid particles. The enhancement of solid surface contact with the gaseous phase assists the reaction between the solid polymeric resin and the elemental fluorine, as well as the heat dissipation into the dense carrier fluid.
