Abstract: A method for completely reducing an inorganic halide to obtain a non-halogen inorganic substance and/or hydride thereof and preferably anhydrous hydrogen halide fluid using inorganic halide substances, such as sulfur hexafluoride, nitrogen trifluoride, tungsten hexafluoride, uranium hexafluoride and others by reduction with a reducing agent at a proper temperature. The reducing agents may be molecular hydrogen, inorganic hydrides and inorganic metallic elements; molecular hydrogen is preferable, but in certain instances the inorganic hydrides are used, as well as inorganic metallic elements such as calcium and magnesium.

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.
