PROCESS FOR THE CONVERSION OF A C_-C_ ALIPHATIC HYDROCARBON INTO NAPTHENIC HYDROCARBONS

摘要

"PROCESS FOR THE CONVERSION OF A C2-C6 ALIPHATIC HYDROCARBON INTO NAPHTHENIC HYDROCARBONS" C2-C6 aliphatic hydrocarbons are converted into easily transportable hydrocarbons of greater molecular weight by a combination process which comprises converting the C2-C6 aliphatic hydrocarbons to aromatic hydrocarbons in a dehydrocyclodimerization reaction zone after which this aromatic product is directly hydrogenated in the presence of hydrogen, preferably from the dehydrocyclodimerization reaction step, to produce a naphthene-rich product stream. It is also an aspect of the invention that the hot hydrogenation reaction zone product stream is used to preheat the feed stream to the dehydrocyclodimerization reaction zone.
