PROCESS FOR THE PRODUCTION OF HYDROCARBONS FROM HETERO- SUBSTITUTED ALKANES

摘要

A product comprising hydrocarbons having at least 2 carbon atoms is produced by contacting a monohalomethane at elevated temperature, e.g. 200 to 600 DEG C, with a synthetic crystalline aluminosilicate zeolite having a silica to alumina molar ratio of at least 12:1 and containing cations of either hydrogen, copper or a metal capable of forming an amphoteric oxide, which cations are introduced either by exchange and/or by deposition, provided that when the cation is hydrogen the zeolite is Theta-1. At temperatures below 330 DEG C the product predominantly comprises aliphatic hydrocarbons, of which a substantial proportion is isoalkanes and isoalkenes.
