ABSTRACT:
High viscosity lubricants are formed by oligomerizing olefins in two stages. The first stage converts a lower olefin feed to distillate range hydrocarbons in the presence of an aluminosilicate zeolite such as ZSM-5. The distillate effluent from the first stage is further polymerized to lubricant range hydrocarbons at elevated temperatures in the presence of a ditertiary alkylperoxide catalyst.
