Abstract
An apparatus for the direct fluorination of solid particles of polymeric resins capable of being fluorinated in which the solid particles are contacted by a flow of a mixture of fluorine and carrier fluid in a solid-gas reactor. In the solid-gas reactor, the fluid flow continuously agitates or fluidizes the solid particles to maintain the solid particles in motion. The degree of motion of the solid particles is a function of the linear velocity of the fluid and of the physical properties of the solid particles such as the solid bulk density, particle size, geometry of the solid particle, and adhesion or agglomeration of solid particles. The solid-gas reactor can be arranged with single or multi-reactors in batch or continous mode.
