    摘要: Disclosed are processes for an isomerization reaction between (E)1-chloro-3,3,3-trifluoropropene and (Z)1-chloro-3,3,3-trifluoropropene. Some of the disclosed processes include the step of contacting a feed stream with a heated surface, where the feed stream includes (E)1-chloro-3,3,3-trifluoropropene, (Z)1-chloro-3,3,3-trifluoropropene or mixtures thereof. The resulting product stream includes (E)1-chloro-3,3,3-trifluoropropene and (Z)1-chloro-3,3,3-trifluoropropene, where the ratio of (E) isomer to (Z) isomer in the product stream is different than the ratio feed stream. The (E) and (Z) isomers in the product stream may be separated from one another.

    摘要: A method for the development or generation of pollution credits by the substitution of lower global warming potential (GWP) mixtures of halogenated hydrocarbons or mixtures of halogenated hydrocarbons with CO2 for fluorocarbons or fluorocarbon-containing compositions of higher GWP, such as for perfluorocarbon compounds (PFC's), hydrofluorocarbon compounds (HFC's), chlorofluorocarbons (CFC's), hydrochlorofluorocarbon compounds (HCFC's), and compositions thereof, in compositions and processes employing the higher GWP compounds, and receive allocation of pollution credits for such substitution.
