A hydrodeoxygenation process for producing a linear alkane from a feedstock comprising a saturated or unsaturated C 10-18 oxygenate that comprises an ester group, carboxylic acid group, carbonyl group and/or alcohol group is disclosed. The process comprises contacting the feedstock with a catalyst comprising (i) about 0.1% to 10% by weight of a metal selected from Group IB or VIII of the Periodic Table, and (ii) about 0.5% to 15% by weight of tungsten, rhenium, molybdenum, vanadium, manganese, zinc, chromium, germanium, tin, titanium, gold, and/or zirconium, at a temperature between about 150 C to 250 C and a hydrogen gas pressure of at least 300 psig. By contacting the feedstock with the catalyst under these temperature and pressure conditions, the C 10-18 oxygenate is hydrodeoxygenated to a linear alkane that has the same carbon chain length as the C 10-18 oxygenate. |
