Gasoline range bio-hydrocarbons are advantageous since they are fully compatible with conventional gasoline, cars, and current infrastructure. Bio-hydrocarbon products are not, however, consistent with each other, but depend on the production technology and feedstock used. Product quality ranges from high-aromatic and high-octane qualities to paraffinic low-octane hydrocarbon mixtures. Bio-gasoline mixtures may contain different amounts of olefins as well as oxygenates.
