Abstract

Methods are provided for oligomerizing a dilute ethylene feed to form oligomers suitable for use as fuels and/or lubricant base oils. The fuels and/or lubricant base oils are formed by oligomerization of impure dilute ethylene with a zeolitic catalyst, where the zeolitic catalyst is resistant to the presence of poisons such as sulfur and nitrogen in the ethylene feed. The oligomers can also be formed in presence of diluents such as light paraffins.

Claims18

Dependent claims

A method for forming fuel and lubricant products, comprising:

exposing a feedstock comprising 50 vol % of ethylene or less to a catalyst comprising a zeolite with 10-member rings under effective oligomerization conditions to produce an oligomerized effluent;
hydroprocessing at least a portion of the oligomerized effluent under effective hydroprocessing conditions to form a hydroprocessed effluent;
and
separating the hydroprocessed effluent to form a fraction having a boiling point of 350° F. (177° C.) or less, one or more lubricant base oil fractions, and at least one diesel fuel fraction having a lower boiling range than at least one lubricant base oil fraction.
