Profitable method for carbon capture and storage

1. A method for sequestering carbon dioxide, comprising the steps of:

converting biomass into paraffinic hydrocarbons,

steam cracking the paraffinic hydrocarbons into olefins; and

polymerizing the olefins into non-biodegradable polyolefins.

2. The method of claim 1 wherein the paraffinic hydrocarbons are produced by gasification followed by Fischer-Tropsch conversion.

3. The method of claim 2 wherein the biomass is wood chips.

4. The method of claim 1 wherein the paraffinic hydrocarbons are produced by hydrotreating of fatty acids and/or fatty acid esters.

5. The method of claim 4 wherein the fatty acids and/or fatty acid esters are oils from plants.

6. The method of claim 4 wherein the fatty acids and/or fatty acid esters are fats from animals.

7. The method of claim 4 wherein the fatty acids and/or fatty acid esters are oils from algae.

8. The method of claim 7 wherein the algae are grown in ponds and/or photo-bioreactors with CO 2 supplied from stationary emission sources.

9. The method of claim 8 wherein the stationary emission source is a coal-fired power plant.

10. The method of claim 1 wherein the olefins comprise of ethylene, propylene, butenes, and butadiene.

11. The method of claim 1 wherein bio-derived hydrogen is produced as byproduct of steam cracking.

12. The method of claim 1 wherein bio-derived pyrolysis gasoline is produced as byproduct of steam cracking.

13. The method of claim 12 wherein the pyrolysis gasoline is used as motor gasoline blend stock.

14. The method of claim 13 wherein the pyrolysis gasoline is hydrogenated prior to use as motor gasoline.

15. The method of claim 1 wherein bio-derived fuel gas is produced as byproduct of steam cracking.

16. The method of claim 15 wherein the bio-derived fuel gas is supplied to the steam cracker furnace.

17. The method of claim 1 wherein the pyrolysis fuel oil yield is less than 1 wt % of the bio-derived paraffinic hydrocarbon.
