  • Patent number: 10442743
    Abstract: The present invention provides a process for the preparation of a (hydro)(chloro)fluoroalkene by contacting a reagent stream comprising a hydrochlorofluoroalkane with a catalyst in a reactor to dehydrochlorinate at least a portion of the hydrochlorofluoroalkane to produce a product stream comprising the (hydro)(chloro)fluoroalkene and hydrogen chloride (HCl), wherein the catalyst is selected from the group consisting of metal oxide catalysts, metal halide catalysts, zero-valent metal catalysts, carbon-based catalysts and mixtures thereof, and wherein (i) the catalyst is chlorinated prior to contacting it with the reagent stream comprising the hydrochlorofluoroalkane; and/or (ii) the contacting step is carried out in the presence of a HCl co-feed.
