Filed:

Sep 19, 2013

Appl. No.:

14/031356

Inventors:

Manish S. Kelkar - Wilmington DE, US
Kenneth Chad Manning - Wilmington DE, US
Kenneth Gene Moloy - Hockessin DE, US

Assignee:

EI DU PONT DE NEMOURS AND COMPANY - Wilmington DE

International Classification:

C07C 1/22

US Classification:

585733

Abstract:

A hydrodeoxygenation process for producing a linear alkane from a feedstock comprising a saturated or unsaturated Coxygenate 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 Coxygenate is hydrodeoxygenated to a linear alkane that has the same carbon chain length as the Coxygenate.

Abstract:

A hydrodeoxygenation process for producing a linear alkane from a feedstock comprising a saturated or unsaturated Coxygenate 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 Coxygenate is hydrodeoxygenated to a linear alkane that has the same carbon chain length as the Coxygenate.
