Abstract

The present application provides charcoal briquettes infused with a flammable composition including fusel oil and/or one or more dehydration products of fusel oil and the flammable compositions including one or more dehydration products of fusel oil.

First claim

The invention claimed is:

1. A charcoal briquette comprising: a charcoal briquette infused with a flammable composition, the flammable composition consisting essentially of: one or more dehydration products of fusel oil, wherein the one or more dehydration products of fusel oil are a multicomponent alcohol mixture.

2. The charcoal briquette of claim 1 , wherein the one or more dehydration products of fusel oil is a byproduct of alcohol production from fermentation.

3. The charcoal briquette of claim 1 , wherein the one or more dehydration products of fusel oil comprises 15% by volume or less of water.

4. The charcoal briquette of claim 1 , wherein the dehydration products of fusel oil comprise one or more distillation fractions from distillation of fusel oil, and wherein the one or more distillation fractions are selected from the group consisting of: distillation fraction A obtained between room temperature and about 105° C., distillation fraction B obtained between about 106° C. and 133° C., distillation fraction C obtained at about 133° C. and above, and a combination thereof.

5. The charcoal briquette of claim 4 , wherein distillation fraction A comprises a multicomponent alcohol mixture comprising two or more alcohols selected from the group consisting of ethanol, propanol, and water; wherein distillation fraction B comprises a multicomponent alcohol mixture comprising two or more alcohols selected from the group consisting of butanols and amyl alcohols; and wherein distillation fraction C comprises a multicomponent alcohol mixture comprising two or more alcohols selected from the group consisting of amyl alcohols, hexanols, and octanols.

6. The charcoal briquette of claim 1 wherein the one or more dehydration products of fusel oil is produced using mechanical filtration dehydration using molecular sieve membrane systems and wherein the dehydration product of fusel oil comprises less than about 15% by volume water.

7. The charcoal briquette of claim 1 wherein the one or more dehydration products of fusel oil is produced using a chemical dehydration method and wherein the dehydration product of fusel oil comprises less than about 15% by volume water.

8. The charcoal briquette of claim 1 , wherein the flammable composition comprises about 5-100% by volume of the one or more dehydration products of fusel oil.

9. A charcoal briquette infused with a flammable composition, the flammable composition comprising:
one or more dehydration products of fusel oil, wherein the one or more dehydration products of fusel oil are a multicomponent alcohol mixture, and
a biodiesel component comprising a combination of fatty-acid alkyl esters (FAAEs).

10. The charcoal briquette of claim 9 , wherein the biodiesel component is derived from a non-petroleum lipid source.

11. The charcoal briquette of claim 9 , wherein the non-petroleum lipid source is selected from the group consisting of: animal fats, virgin vegetable oils, used cooking oil, brown grease, and combinations thereof.

12. The charcoal briquette of claim 9 , wherein the one or more dehydration products of fusel oil make up about 5-99% by volume of the flammable composition and the biodiesel component makes up about 1-95% by volume of the flammable composition.

13. The charcoal briquette of claim 1 , wherein the flammable composition has a flash point of about 38° C. or greater.

14. The charcoal briquette of claim 9 , wherein the flammable composition consists of:
the one or more dehydration products of fusel oil at about 5-99% by volume of the flammable composition, wherein the one or more dehydration products of fusel oil have about 15% by volume or less of water; and
a biodiesel component at about 1-95% by volume of the flammable composition, wherein the biodiesel component consists of a combination of fatty-acid alkyl esters (FAAEs).
