Abstract: A process for the fluorination of a chlorinated C3 alkane or alkene compound having at least one chlorine atom into a fluorinated C3 alkane or alkene compound having at least one fluorine atom includes the following steps: a) contacting, in a reactor, the chlorinated compound with hydrogen fluoride in gas phase in the presence of a fluorination catalyst to produce a fluorinated compound, and b) regenerating the fluorination catalyst used in step a). The step (b) of regenerating the fluorination catalyst comprises (c) the treatment of said fluorination catalyst with an oxidizing agent-containing gas flow to form an oxidized fluorination catalyst, and (d) the treatment of the oxidized fluorination catalyst obtained in step (c) with a gaseous mixture comprising a reducing agent and an inert gas. The catalyst regenerated in step b) is reused in step a) and the reducing agent is selected from C1-C10 hydrohalocarbons.
