PROCESS FOR THE CONVERSION OF OLEFINIC COMPOUNDS INTO HIGH VISCOSITY LUBES

摘要

A two-stage process is provided whereby in the first stage light olefins are converted over a ZSM-5 type catalyst to gasoline and distillate liquids which are then converted in a second catalytic stage under milder conditions of temperature and/or pressure over substantially the same or a different ZSM-5 type catalyst to yield lube range products having superior viscosity index properties.
