1. A METHOD FOR CATALYTICALLY TREATING A SATURATED HYDROCARBON MATERIAL CONTAINING SATURATED FLUORINE CONTAINING ORGANIC COMPOUNDS AS IMPURITY FOR THE REMOVAL OF SAID IMPURITY COMPRISING MAINTAINING A BODY OF AT LEAST ONE FINELY DIVIDED METAL CATALYST SELECTED FROM THE GROUP OF METALS CONSISTING OF ZINC, MAGNESIUM, IN A FLUIDMIUM, COPPER, LEAD AND ALUMINUM, IN A FLUIDIZED CONDITION IN A TREATING ZONE AT A TEMPERATURE BETWEEN THE LIMITS OF 150* F. AND 350* F., PASSING SAID SATURATED HYDROCARBON MATERIAL CONTAINING SAID IMPURITY IN A VAPOROUS CONDITION AT A TEMPERATURE BETWEEN THE LIMITS OF 150* F. AND 350* F. INTO SAID BODY OF FLUIDIZED METAL CATALYST IN SAID ZONE TO DECOMPOSE THE ORGANIC FLUORINE COMPOUNDS AND LIBERATE HYDROGEN FLUORIDE, IMMEDIATELY SEPARATING THE LIBERATED HYDROGEN FLUORIDE FROM THE HYDROCARBON VAPORS BY PASSING THE EFFLUENT VAPORS FROM THE FLUIDIZED METAL CATALYST THROUGH A FLUIDIZED BODY OF ACTIVATED CARBON IN SAID ZONE ABOVE AND IN CONTACT WITH SAID METAL CATALYST, AND REMOVING TREATED HYDROCARBON MATERIAL FROM THE BODY OF ACTIVATED CARBON IN SAID ZONE AS THE PRODUCT OF THE PROCESS.
