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.
本发明公开了一种通过水解氧化过程从含有酯基、羧酸基、羰基和/或醇基的饲料中生成线性烷烃的方法。该过程包括将饲料与催化剂接触,所述催化剂包括以下成分:(i)周期表IB或VIII族中选择的金属,其重量占0.1%至10%;(ii)钨、铼、钼、钒、锰、锌、铬、锗、锡、钛、金和/或锆,其重量占0.5%至15%。所述接触温度为150℃至250℃,氢气压力至少为300 psig。通过在这些温度和压力条件下将饲料与催化剂接触,C10-18氧化物被水解氧化为具有与C10-18氧化物相同碳链长度的线性烷烃。
