    Abstract: A method of treatment of reactant fluids such as hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), hydrochlorocarbons (HCCs), and hydrocarbons (HCs) for the production of new chemical fluids. Another method of treatment for the transformation of the reactant fluids having impurities present in the chlorofluorocarbons (CFCs) or fluorocarbons (FCs) for yielding a high quality chemical product. Reactant fluids with impurities present in used CFC or FC may form an azeotropic mixture. A photochemical reaction is used wherein the reactant fluids are molecules with hydrogen atoms in a hydrogen-carbon bond. The process is comprised of the following steps: placing the reactant fluids into a process compartment of the photochemical reactor; placing halogen fluid or oxygen fluid into the process compartment of the photochemical reactor, wherein the halogen fluid is selected from a group consisting of chlorine (Cl2), bromine (Br2) and iodine (I2); and irradiating the fluids and the halogen or oxygen fluid using radiant energy from lamps operating in the visible and ultraviolet light regions of the electromagnetic spectrum to conduct thermolysis, photolysis and photochemical treatment by halogenating or oxidizing the molecules of the reactant fluids with the halogen or oxygen fluids to form halogenated or oxidized fluids during a dwell time period.

    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.

    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.
