A catalyst for producing higher carbon number hydrocarbons, e.g., benzene from low carbon number hydrocarbons such as methane has been developed. The catalyst comprises a porous support such as ZSM-5 which has dispersed thereon rhenium and a promoter metal such as iron, cobalt, vanadium, manganese, molybdenum, tungsten and mixtures thereof. A process for preparing the catalyst and a process for converting low carbon number aliphatic hydrocarbons to higher number hydrocarbons in the presence of CO or CO at conversion conditions are also described.

1-Chloro-l,2,2-trifluoroethylene or 1,2,2-trifluoroethylene is prepared by reacting 1,1,2-trichloro-1,2,2-trifluoroethane and hydrogen in the presence of a catalyst which comprises at least one metal selected from the group consisting of palladium, rhodium and ruthenium and at least one metal selected from the group consisting of mercury, lead, cadmium, tin, indium, copper, bismuth, thallium and silver and a carrier selected from the group consisting of Al.sub.2 O.sub.3, SiO.sub.2 and activated carbon, whereby selectivities and yields of 1-chloro-1,2,2-trifluoroethylene or 1,2,2-trifluoroethylene are optimized by selecting the kinds of metals and supports.
