Patent ID: 7928272

Claim:
A process for production of C 2 H 2 F 2 from reaction of at least one of a methane or natural gas with a fluorocarbon feed, comprising the steps of: (a) reacting the at least one of methane or natural gas with the fluorocarbon feed under non-oxidative conditions in a high temperature reactor, at a temperature of above about 1150K and a residence time under 0.1 seconds to form a reaction product mixture having the C 2 H 2 F 2 as the major reaction component thereof; (b) cooling said reaction product mixture to a temperature sufficiently low to substantially inhibit polymerization of the C 2 H 2 F 2 ; wherein: said fluorocarbon feed is selected from the group consisting of hydrofluorocarbons, halofluorocarbons and hydrohalofluorocarbons; a selectivity of C 2 H 2 F 2 as a percentage of gaseous reaction products excluding unreacted fluorocarbon and at least one of methane and natural gas exceeds 60%; and a yield of C 2 H 2 F 2 exceeds about 44%.
