Process for the conversion of olefinic compounds into high viscosity lubes |
(57) 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.
