ABSTRACT:
This invention relates to improved catalysts for gaseous phase fluorination of aliphatic chlorinated and chlorofluorinated derivatives by hydrofluoric acid. The catalysts are characterized by an active carbon support having a total specific surface area greater than about 1000 m.sup.2 /g but less then about 2000 m.sup.2 /g, a surface area of pores of 40 to 50 .ANG. in radius above about 5 m.sup.2 /g but less then about 15 m.sup.2 /g, a surface area of pores greater than or equal to 250 .ANG. in radius above about 2 m.sup.2 /g but less than about 6 m.sup.2 /g, which has been impregnated with an aqueous chromium sulfate solution and dried. This invention also relates to gaseous phase fluorination processes for chlorinated or chlorofluorinated derivatives utilizing these catalysts in fluidized bed reactors.
