Fatty-acid methyl esters (FAME) are considered a renewable source of raw materials for the
chemical industry, including their use in biodiesel fuel mixtures. In the following manuscript, we
describe the cross-metathesis reactions of a corn oil-derived FAME mixture with isobutylene and other
branched light olefins. Cross-metathesis reactions are also reported with styrene. Cross-metathesis
reactions were done with methyl oleate as a reference. These reforming reactions were done in an
effort to increase the volatility of the fuel mixtures, as well as introduce branching or the phenyl group
into the hydrocarbon chains. The resulting metathesis products contain high percentages of biorenewable
carbon (46-100%). The chemistry represents a new approach to the preparation of green fuels - as a biorenewable stream
is merged with high volume petroleum-derived streams.
Keywords: Biodiesel, biorenewable, catalysis, fatty-acid methyl esters, olefin metathesis, reforming.
