PROCESS FOR MAKING LINEAR LONG-CHAIN ALKANES FROM RENEWABLE FEEDSTOCKS USING CATALYSTS COMPRISING HETEROPOLYACIDS

摘要

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.

1. A hydrodeoxygenation process for producing a linear alkane from a feedstock comprising a saturated or unsaturated C10-18 oxygenate comprising a moiety selected from the group consisting of an ester group, carboxylic acid group, carbonyl group, and alcohol group, wherein the process comprises:
a) contacting said 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, wherein the C10-18 oxygenate is hydrodeoxygenated to a linear alkane, and wherein the linear alkane has the same carbon chain length as the C10-18 oxygenate; and b) optionally, recovering the linear alkane produced in step (a).
