Abstract	Introduction The use of renewable vegetable oils to produce biodiesel has drawn considerable public attention. However, as-produced biodiesel has some drawbacks such as low stability and fungibility with regular diesel. An interesting additional process to biodiesel production is conversion to alkanes, which can be used as normal diesel. Triglyceride molecules in vegetable oils contain fragments of C14 to C20 straight chains, which can be converted to long paraffins that bear a potentially high cetane number (CN), but at the same time they may result in increased cloud point (CP). In order to be used in regular diesel, these molecules have to undergo mild isomerization to produced mono-branched isoparaffins with still acceptable CN and lower CP. In this work, methyloctanoate (MeOct) has been used as a model compound to study the conversion of biodiesel-like oxygenates to paraffins and isoparaffins, which meet the above requirements. To achieve this goal we have investigated two consecutive catalytic steps: first, deoxygenation of oxygenates to paraffinic compounds and second, mild isomerization of straight-chain products to slightly branched isoparaffins.
