PROCEDE DE PRODUCTION DE DISTILLAT PAR OLIGOMERISATION CATALYTIQUE D'OLEFINES EN PRESENCE DE METHANOL ET/OU DIMETHYL ETHER

摘要

The invention relates to a process for producing distillate by oligomerization starting with a hydrocarbon-based charge in the presence of methanol and/or dimethyl ether, which may especially be of plant origin. By addition of an oxygenated compound, this process makes it possible to reduce the amounts of olefins whose chain length is too short to be exploited (typically C10, or even less) and to increase the yields of C10+ olefins.
