Abstract: Described herein are materials and methods for improved catalytic oligomerization of an ethylene monomer and/or propylene monomer. The present disclosure teaches oligomerizing the ethylene monomer or propylene monomer to produce oligomers. Also described is a heterogeneous catalyst comprising sulfate modified nickel on titanium modified alumina and a surface modification with yttrium (Y) suitable for use in the disclosed oligomerization.
