Profitable method for carbon capture and storage
View Patent ↗The present invention generally relates to a method for sequestering carbon dioxide. Biomass is converted into paraffinic hydrocarbons. The paraffinic hydrocarbons are steam cracked into olefins. The olefins are polymerized into non-biodegradable polyolefins.
1. A method comprising steam cracking paraffinic hydrocarbons into olefins, wherein
the paraffinic hydrocarbons are derived from a biomass; and
bio-derived pyrolysis gasoline comprising C 5 -C 10 olefins is produced as a byproduct of the steam cracking.
2. The method of claim 1 , wherein the paraffinic hydrocarbons are produced by gasification followed by Fischer-Tropsch conversion.
3. The method of claim 1 , wherein the paraffinic hydrocarbons are produced by the hydrotreating of fatty acids and/or fatty acid esters.
4. The method of claim 3 , wherein the fatty acids and/or fatty acid esters comprise oils from plants.
5. The method of claim 3 , wherein the fatty acids and/or fatty acid esters comprise fats from animals.
6. The method of claim 3 , wherein the fatty acids and/or fatty acid esters comprise oils from algae.
7. The method of claim 6 , wherein the algae are grown in ponds and/or photo-bioreactors with CO 2 supplied from a stationary emission source.
8. The method of claim 7 , wherein the stationary emission source is a coal-fired power plant.
9. The method of claim 1 , wherein the olefins comprise ethylene, propylene, butenes, and butadiene.
10. The method of claim 1 , wherein bio-derived hydrogen is produced as a byproduct of steam cracking.
11. The method of claim 1 , wherein bio-derived fuel gas is produced as a byproduct of steam cracking.
12. The bio-derived pyrolysis gasoline produced by the method of claim 1 , wherein the bio-derived pyrolysis gasoline comprises about 30 wt % to about 50 wt % aromatics and about 5 wt % to about 20 wt % n-paraffins.
13. A motor gasoline comprising the bio-derived pyrolysis gasoline of claim 1 .
14. The method of claim 1 , wherein the steam cracking produces a steamcracking product comprising light olefins, the bio-derived pyrolysis gasoline, and pyrolysis fuel oil.
15. The steam cracking product of claim 14 , wherein the pyrolysis fuel oil yield is less than 1 wt % of the paraffinic hydrocarbons.
16. The motor gasoline of claim 13 , wherein the bio-derived pyrolysis gasoline is hydrogenated prior to use in the motor gasoline.
17. A method comprising steam cracking paraffinic hydrocarbons into olefins, wherein:
the paraffinic hydrocarbons are derived from a biomass;
the steamcracking produces a steamcracking product comprising light olefins, pyrolysis gasoline, and pyrolysis fuel oil; and
the pyrolysis fuel oil yield is less than 1 wt % of the paraffinic hydrocarbons.
18. The method of claim 17 , wherein the paraffinic hydrocarbons are produced by the hydrotreating of fatty acids and/or fatty acid esters.
19. The method of claim 18 , wherein the fatty acids and/or fatty acid esters comprise oils from plants.
20. The method of claim 18 , wherein the fatty acids and/or fatty acid esters comprise fats from animals.
21. The method of claim 18 , wherein the fatty acids and/or fatty acid esters comprise oils from algae.
22. The method of claim 21 , wherein the algae are grown in ponds and/or photo-bioreactors with CO 2 supplied from a stationary emission source.
23. The method of claim 17 , wherein the olefins comprise ethylene, propylene, butenes, and butadiene.
24. The method of claim 17 , wherein bio-derived hydrogen is produced as byproduct of the steam cracking.
25. The method of claim 17 , wherein bio-derived fuel gas is produced as a byproduct of the steam cracking.
26. The pyrolysis gasoline produced by the method of claim 17 , wherein the pyrolysis gasoline comprises C 5 -C 10 olefins.
27. The pyrolysis gasoline produced by the method of claim 17 , wherein the pyrolysis gasoline comprises about 30 wt % to about 50 wt % aromatics and about 5 wt % to about 20 wt % n-paraffins.
28. The steam cracking product of claim 17 .
29. A motor gasoline comprising the pyrolysis gasoline of claim 17 .
30. The motor gasoline of claim 29 , wherein the pyrolysis gasoline is hydrogenated prior to use in the motor gasoline.
