Abstract

The invention relates to granulated gas charges and their use. Said granulated gas charges, whose combustion fumes are nitrogen-free and low in carbon monoxide, contain a) between 5 and 50% by weight binders; b) between 0 and 90% by weight oxidizing agents; and/or c) between 0 and 75% of an organic, notably nitrogen-free, fuel.

Claims

1. Granulated gas charges having combustion vapors that are free of nitrogen oxide and are deficient in carbon monoxide, comprising

a) 5 to 50% by weight of a binding agent;

b) oxidizing agents in a quantity 0 to 90% by weight of an oxidizing agent; and

c) 0 to 75% by weight of an organic fuel.

2. Gas charges according to claim 1, wherein the binding agent is at least one binder selected from the group consisting of cellulose acetate, cellulose acetobutyrate, cellulose triacetate, nitrocellulose and polyvinyl butyral.

3. A gas charge according to claim 1, wherein the is at least one oxidizing agent is selected from the group consisting of from alkali perchlorates, alkaline earth metal perchlorates, zinc peroxide, iron oxides, cerium dioxide, copper oxide, manganese dioxide and permanganates.

4. A gas charge according to claim 1, wherein the at least one oxidizing agent is potassium perchlorate.

5. A gas charge according to claim 1, wherein the at least one organic fuel is acids selected from the group consisting of terephthalic acid, fumaric acid and ascorbic acid.

6. A gas charge according to claim 1, wherein the gas charges further comprise at least one aggregate.

7. A gas charge according to claim 6, wherein said aggregate is a combustion moderator.

8. A gas charge according to claim 6, wherein the aggregate is selected from the group consisting of aluminum oxide, zinc oxide, alkali metal silicates, alkaline earth metal silicates, mineral clays, cement, gypsum, alkali metal carbonates alkaline earth metal carbonates, alkali metal oxalates, alkaline earth metal oxalates, and oxalic acid.

9. A gas charge according to claim 1, wherein the gas charges further comprise a coating additives selected from the group consisting of graphite, water glass, nitrates of alkali metal, perchlorates of alkali metals, nitrates of alkaline earth metals and perchlorates of alkaline earth metals.

12. The gas charge of claim 1, consisting of cellulose acetate, potassium perchlorate, terphthalic acid.

13. The gas charge of claim 6, consisting of cellulose acetate, potassium perchlorate, aluminum oxide and terphthalic acid.

14. The gas charge of claim 9, consisting of cellulose acetate, potassium perchlorate, aluminum oxide, graphite and terphthalic acid.

15. The gas charge of claim 1, wherein said carbon monoxide is present as less than 0.0001 vol. % of the combustion vapor.

16. The gas charge of claim 15, wherein the combustion vapor contains from 56–

57 vol % carbon dioxide.

17. The gas charge of claim 16, wherein the combustion vapor contains from 42–

43 vol % water.

10. A gas charge consisting of from 57–

11. A gas charge consisting of 20 percent by weight cellulose acetate, 57 percent by weight potassium perchlorate, and 23 percent aluminum oxide.

18. A composition consisting of 25 wt % cellulose acetate and 75 wt % potassium perchlorate.

19. A composition consisting of 20 wt % cellulose acetate, 57% potassium perchlorate, and 23% aluminum oxide.

20. A gas charge, comprising

a) 1 to 50% by weight of at least one binding agent;

b) at least one oxidizing agent; and

c) at least one nitrogen free organic fuel, wherein said gas charge is nitrogen free.

21. The gas charge of claim 20, wherein combustion vapors from the gas charge are free of nitrogen oxide and are deficient in carbon monoxide.

22. A gas charge, comprising

a) 1 to 50% by weight of at least one binding agent;

b) at least one of an oxidizing agent and a nitrogen free organic fuel, wherein said gas charge is nitrogen free.

23. The gas charge of claim 22, wherein combustion vapors from the gas charge are free of nitrogen oxide and are deficient in carbon monoxide.

26. The gas charge of claim 23, wherein said carbon monoxide is present as less than 0.0001 vol. % of the combustion vapor.

24. A gas charge comprising 1 to 50% by weight of at least one binding agent and an oxidizing agent, wherein said gas charge is nitrogen free.
