Abstract

The invention relates to renewable hydrocarbons, and more particularly to biomass-based diesel fuel produced in a process including hydrodeoxygenation (HDO) of phenolic lipids. The process may generally include combining a phenolic lipid and a hydrocarbon diluent to provide a hydrocarbon-diluted phenolic lipid then subjecting the hydrocarbon-diluted phenolic lipid to hydrodeoxygenation in a reactor to provide a reactor effluent including a hydrodeoxygenated phenolic lipid. The hydrodeoxygenated phenolic lipid is separated from the reactor effluent.

Claims (29)

1 . A blended feedstock composition for use in a hydrodeoxygenation process, the blended feedstock composition comprising:

a. a phenolic lipid; and

b. a biorenewable lipid feedstock having an oxidative stability;

c, wherein the biorenewable lipid feedstock comprises at least 1 wt. % free fatty acid;

d, wherein the blended feedstock composition has an oxidative stability higher than the oxidative stability of the biorenewable lipid feedstock.

2 . The blended feedstock composition of claim 1 wherein the blended feedstock composition comprises between about 0.5 to 10 wt. % of the phenolic lipid.

3 . The blended feedstock composition of claim 1 wherein the blended feedstock composition comprises about 1 wt. % of the phenolic lipid and about 99 wt. % of the biorenewable lipid feedstock.

4 . The blended feedstock composition of claim 1 wherein the phenolic lipid is 2 nd boil Cashew Nut Shell Liquid (CNSL).

5 . The blended feedstock composition of claim 4 wherein the blended feedstock composition comprises about 1 wt. % CNSL and has a Rancimat induction time greater than 9 hours.

6 . The blended feedstock composition of claim 4 wherein the blended feedstock composition comprises about 2 wt. % CNSL and has a Rancimat induction time greater than 10 hours.

7 . The blended feedstock composition of claim 1 wherein the blended feedstock composition has a Rancimat induction time greater than 10 hours as measured at 110° C. test temperature.

8 . The blended feedstock composition of claim 1 wherein the blended feedstock composition has a Rancimat induction time greater than 12 hours as measured at 110° C. test temperature.

9 . The blended feedstock composition of claim 1 wherein the biorenewable lipid feedstock comprises at least 5 wt. % free fatty acid.

10 . A method of manufacturing a feedstock for a hydrodeoxygenation process, said method comprising:

a. taking a biorenewable lipid feedstock comprising at least 1 wt. % free fatty acid;

b. blending the biorenewable lipid feedstock with between about 0.5 to 10 wt % of a phenolic lipid to produce a blended feedstock.

11 . The method of claim 10 wherein the blending is performed as the biorenewable lipid feedstock and the phenolic lipid are transferred to a blended feedstock storage tank.

12 . The method of claim 10 wherein the phenolic lipid is 2 nd boil Cashew Nut Shell Liquid (CNSL).

13 . The method of claim 10 wherein the biorenewable lipid feedstock comprises at least 5 wt. % free fatty acid.

14 . The method of claim 10 further comprising subjecting the blended feedstock to hydrodeoxygenation in a reactor to provide a reactor effluent including a hydrodeoxygenated blended feedstock.

15 . The method of claim 12 wherein the blended feedstock comprises about 1 wt. % CNSL and has a Rancimat induction time greater than 9 hours.

16 . The method of claim 12 wherein the blended feedstock comprises about 2 wt. % CNSL and has a Rancimat induction time greater than 10 hours.

17 . A method for producing hydrocarbons comprising:

a. taking a biorenewable lipid feedstock comprising at least 1 wt. % free fatty acid;

b. blending the biorenewable lipid feedstock with between about 0.5 to 10 wt % of a phenolic lipid to produce a blended feedstock;

c. subjecting the blended feedstock to a hydrodeoxygenation process comprising contacting the blended feedstock with a hydrogen-rich gas and a catalyst at a temperature and pressure which are elevated above an ambient temperature and pressure to produce a reactor effluent; and

d. recovering a hydrocarbons fraction from the reactor effluent.

18 . The method of claim 17 wherein the phenolic lipid is 2 nd boil Cashew Nut Shell Liquid (CNSL).

19 . The method of claim 17 wherein the biorenewable lipid feedstock comprises at least 5 wt. % free fatty acid.
