Abstract

Disclosed are novel engineered fuel feed storks, feed stocks produced by the described processes, and methods of making the fuel feed stocks. Components derived from processed MSW waste streams can be used to make such feed stocks which are substantially free of glass, metals, grit and noncombustibles. These feed stocks are useful for a variety of purposes including as gasification and combustion fuels.

Claims (48)

1. An engineered fuel feed stock, comprising:

an H/C ratio of between about 0.025 (w/w) and about 0.20 (w/w);

an O/C ratio of between about 0.01 (w/w) and about 1.0 (w/w);

a moisture content of between 10 wt. % and 30 wt. %; and

an ash content of less than about 10 wt. %,

wherein the engineered fuel feed stock contains biodegradable and non-biodegradable wastes and substantially no glass, metals, grit, and noncombustibles.

2. The engineered fuel feed stock of claim 1 , wherein the moisture content is between 12 wt. % and 28 wt. %.

3. The engineered fuel feed stock of claim 2 , wherein the moisture content is between 10 wt. % and 20 wt. %.

4. The engineered fuel feed stock of claim 1 , wherein the ash content is less than about 5 wt. %.

5. The engineered fuel feed stock of claim 1 , further comprising:

a sulfur content of less than about 2 wt. %.

6. The engineered fuel feed stock of claim 1 , further comprising:

a chlorine content of less than about 1 wt. %.

7. The engineered fuel feed stock of claim 1 , further comprising:

an HHV of between about 11,000 BTU/lb and about 15,000 BTU/lb.

8. The engineered fuel feed stock of claim 1 , further comprising:

a volatile matter content of between about 40 wt. % and about 80 wt. %.

9. The engineered fuel feed stock of claim 8 , wherein the volatile matter content is between about 60% and about 70%.

10. The engineered fuel feed stock of claim 1 , further comprising:

a volatile matter content of between about 80 wt. % and about 95 wt. %.

11. The engineered fuel feed stock of claim 1 , wherein the H/C ratio is between about 0.08 (w/w) and about 0.15 (w/w).

12. The engineered fuel feed stock of claim 11 , wherein the H/C ratio is between about 0.11 (w/w) and about 0.15 (w/w).

13. The engineered fuel feed stock of claim 1 , wherein the H/C ratio is between about 0.05 (w/w) and about 0.1 (w/w).

14. The engineered fuel feed stock of claim 1 , where in a hydrogen content is between about 3 wt. % and about 10 wt. % and a carbon content is between about 30 wt. % and about 80 wt. %.

15. The engineered fuel feed stock of claim 1 , wherein the O/C ratio is between about 0.01 (w/w) and about 0.05 (w/w).

16. The engineered fuel feed stock of claim 1 , wherein the O/C ratio is between about 0.05 (w/w) and about 0.12 (w/w).

17. The engineered fuel feed stock of claim 1 , wherein the O/C ratio is between about 0.15 (w/w) and about 0.3 (w/w).

18. The engineered fuel feed stock of claim 1 , wherein the engineered fuel feed stock comprises at least one component derived from a processed MSW waste stream.

19. An engineered fuel feed stock, comprising:

an H/C ratio of between about 0.025 (w/w) and about 0.20 (w/w);

an O/C ratio of between about 0.15 (w/w) and about 0.3 (w/w);

a moisture content of between 10 wt. % and 30 wt. %; and

an ash content of less than about 10 wt. %,

wherein the engineered fuel feed stock contains biodegradable and non-biodegradable wastes and substantially no glass, metals, grit, and noncombustible waste.

20. The engineered fuel feed stock of claim 15 , further comprising:

a hydrogen content of between about 3 wt. % and about 10 wt. % and a carbon content of between about 30 wt. % and about 80 wt. %.

21. The engineered fuel feed stock of claim 15 , further comprising:

an HHV of between about 11,000 BTU/lb and about 15,000 BTU/lb.

22. An engineered fuel feed stock, comprising:

an H/C ratio of between about 0.025 (w/w) and about 0.20 (w/w);

an O/C ratio from about 0.01 (w/w) to about 0.12 (w/w);

an ash content of less than about 10 wt. %,

wherein the engineered fuel feed stock contains biodegradable and non-biodegradable wastes and substantially no glass, metals, grit, and noncombustible waste.

23. The engineered fuel feed stock of claim 22 , further comprising:

a hydrogen content of between about 3 wt. % and about 10 wt. % and a carbon content of between about 30 wt. % and about 80 wt. %.

24. The engineered fuel feed stock of claim 22 , further comprising:

an HHV of between about 11,000 BTU/lb and about 15,000 BTU/lb.
