Abstract (en)

[origin: WO2007138210A1] The invention relates to a method for producing hydrofluorocarbons. Said method comprises a step of reacting at least one hydro(fluoro)chlorocarbon or chlorocarbon with hydrofluoric acid in a gaseous phase in the presence of a catalyst, and a step of separating fluorination reaction products from the mixture. The method is characterised in that the gaseous flow from the reaction is compressed by means of a compressor before being subjected to the separation step. The invention also relates to a device for implementing said method.
