Abstract

A catalyst composition for use in oligomerization of olefins contained in refinery distillate streams including paraffins, naphthenes, and aromatics therein, the catalyst consisting of a first constituent which is at least one aluminum halide; and a second constituent which is at least one alkoxide of a transition metal of Group IVB of the Periodic Table and which has a general formula: EQU M(OR).sub.4, where M is selected from the group consisting of metals of Group IVB of the Periodic Table and R is one of (a) an alkyl group having from 1-12 carbon atoms or (b) an alkylaryl group having an alkyl chain having from 1-12 carbon atoms.
