Methods of forming propylene and alkylate are provided. The methods may include providing a stream that includes n-butenes, and contacting the stream with ethylene in the presence of a disproportionation catalyst to form a stream that includes propylene. Propylene then may be removed from the stream, and the stream may be disposed in an alkylation unit to form alkylate.

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.
