A hydrodeoxygenation process for producing a linear alkane from a feedstock comprising a saturated or unsaturated C10-18 oxygenate that comprises an ester group, carboxylic acid group, carbonyl group and/or alcohol group is disclosed. This process comprises contacting the feedstock with (i) a catalyst comprising about 0.1 % to about 10% by weight of a metal selected from Group IB, VIB, or VIII of the Periodic Table, and (ii) a heteropolyacid or heteropolyacid salt, at a temperature between about 150 °C to about 250 °C and a hydrogen gas pressure of at least about 300 psig. By contacting the feedstock with the catalyst and heteropolyacid or heteropolyacid salt under these temperature and pressure conditions, the C10-18 oxygenate is hydrodeoxygenated to a linear alkane that has the same carbon chain length as the C10-18 oxygenate.
本发明公开了一种从含有酯基、羧基、羰基和/或醇基的饱和或不饱和C10-18含氧化合物的原料中生产线性
烷烃的加氢脱氧过程。该过程包括将原料与(i)催化剂接触,所述催化剂包括周期表中选择自IB、VIB或VIII族的
金属,其重量约为0.1%至约10%,以及(ii)杂多酸或杂多酸盐,在温度在约150℃至约250℃和至少约300 psig的
