Abstract:
1. A process for the production of fluorinated olefins comprising exposing, in a gas phase, a fluorinated and chlorinated alkane stream comprising HCFC-244fa to conditions effective to convert at least about 70% by weight of said alkane stream to an olefin stream comprising HFO-1234ze, wherein said exposing step comprises exposing said alkane stream to a catalyst selected from the group consisting of LiF, NaF, KF, MgF 2 , NiF 2 , LiCl, KCl, MgCl 2 , NiCl 2 , CuCl 2 , ZnCl 2 , NaCl, CsCl, CsF, activated carbon, Fe, Co, Ni, Cu, and combinations of two or more of these, wherein said catalyst is optionally supported by a substrate selected from the group consisting of carbon, activated carbon, graphite, fluorinated graphite, and combinations of two or more of these.
