Systems and methods for producing fluorocarbons are provided that include contacting a saturated halogenated fluorocarbon with hydrogen and catalyst to produce a saturated hydrofluorocarbon and an unsaturated fluorocarbon. Aspects of the present invention describe systems and methods for contacting saturated halogenated fluorocarbons such as CF3CClFCF3 and/or CF3CCl2CF3 with hydrogen and catalyst. Systems and methods of the present invention also describe contacting saturated halogenated fluorocarbons with catalysts having one or more of K, Zr, Na, Ni, Cu, Ni, Zn, Fe, Mn, Co, Ti, and Pd. Aspects of the present invention also describe contacting saturated halogenated fluorocarbons with hydrogen under pressure. Saturated hydroflourocarbons and unsaturated fluorocarbons produced in accordance with the systems and methods of the present invention can include one or more of CF3CFHCF3, CF3CH2CF3, CF3CHClCF3, CF3CF=CF2, CF3CH=CF2, and CF3CCl=CF2.

L'invention concerne des systèmes et des procédés de production de fluorocarbures, consistant à mettre en contact un fluorocarbure halogéné saturé avec de l'hydrogène et un catalyseur pour produire un hydrofluorocarbure saturé et un fluorocarbure insaturé. Certains aspects de cette invention concernent des systèmes et des procédés pour mettre en contact des fluorocarbures halogénés saturés tels que CF¿3?CClFCF¿3? et/ou CF¿3?CCl¿2?CF¿3? avec de l'hydrogène et un catalyseur. Des systèmes et des procédés de la présente invention concernent également la mise en contact de fluorocarbures halogénés saturés avec des catalyseurs présentant un ou plusieurs éléments parmi K, Zr, Na, Ni, Cu, Ni, Zn, Fe, Mn, Co, Ti et Pd. Certains aspects de ladite invention se rapportent en outre à la mise en contact de fluorocarbures halogénés saturés avec de l'hydrogène sous pression. Des hydrofluorocarbures saturés et des fluorocarbures insaturés produits selon les systèmes et procédés de cette invention peuvent comporter un ou plusieurs éléments parmi CF¿3?CFHCF¿3?, CF¿3?CH¿2?CF¿3?, CF¿3?CHClCF¿3?, CF¿3?CF=CF¿2?, CF¿3?CH=CF¿2? et CF¿3?CCl=CF¿2?.
