Abstract
An apparatus and method are provided for the defluorination of a liquid hydrocarbon mixture, containing organic fluorides, produced during the conversion of hydrocarbons using a fluorine-containing catalyst. In one embodiment, both thermal means and a contacting material are used to effectuate a more complete defluorination. The liquid hydrocarbon mixture is extracted from a distillation column and heated sufficiently in the thermal means to decompose at least some of the organic fluorides. The effluent from the thermal means is separated into a vaporous and a liquid effluent. The liquid effluent is passed to the bottom of the distillation column where it undergoes further defluorination through contact with the contacting material.
