Benefits of technology

[0006]The present invention relates to a non-toxic fuel composition, which is based on a vegetable oil. In one aspect, the present invention relates to use of a composition comprising a base formulation of one or more alkyl esters of a C6-C16 carboxylic acid or mixtures thereof as a fuel composition. The composition is in specific embodiments used as a lighter fluid, heating fuel, fuel for cooking and/or cooling fuel, preferably a lamp oil, such as a lamp oil for indoor and/or outdoor use. In one embodiment, the composition comprises at least 50%, such as at least 60%, for example at least 70%, such as at least 80%, for example at least 90% by weight of one or more alkyl esters of a C6-C16 carboxylic acid or mixtures the...

Problems solved by technology

These fuel compositions suffer from the major drawback that they are highly toxic, especially upon ingestion.
Even the slightest quantities of these dangerous fuels are sufficient to give heavy lung damages.
Children are especially at risk, because infan...

example 1

[0235]The following example illustrates specific composition and methods of producing those according to the present invention.

TABLE 3IngredientsAmountVegetable oil1 litreEthanol or methanol70-200 mlPotassium hydroxide (KOH) or1-5 gramsodium hydroxide (NaOH)Butanol2-15% (w / w)Antioxidant~

[0236]The composition was prepared as follows:

[0237]First, Ethanol or methanol and Potassium hydroxide (KOH) or sodium hydroxide (NaOH) is mixed, and that mixture is then subsequently mixed with the vegetable oil. The mixture is heated until 50-60 degrees Celsius, and stirred. The mixture is precipitated and a glycerol fraction is separated from a fatty acid fraction of the vegetable oil. This step results in the production of a methyl ester (where methanol is used) or ethyl ester (where ethanol is used).

[0238]The methyl ester or ethyl ester is mixed with butanol to a final concentration of 2-15% butanol. Finally, an antioxidant is optionally added to prevent premature oxidation of the composition.

Preparation of Biodiesel

[0242]Biodiesel may be prepared from any vegetable oil, as defined herein. For example, by the following method. First, 200 mL of canola oil was added to an round bottom flask and heated to 55° C. Then, 50 mL of methanol were added along with 2.9 g of sodium hydroxide. The mixture was heated and stirred for 40 minutes and then allowed to cool to room temperature. The reaction mixture was then washed with equal volumes of DI water five times. The water was separated from the reaction mixture. The solution was allowed to sit in the separatory funnel for 5 hours. During this time the glycerine (bottom layer) separated from the biodiesel (top layer). The biodiesel was then separated and collected.

Abstract

Use of a composition comprising a base formulation of one or more alkyl esters of a C6-C16 carboxylic acid or mixtures thereof as a fuel composition is provided. The use of the fuel composition is specifically provided for use as a lamp fuel, a lighter fuel, and/or a fuel for cooking, heating or cooling. Specifically, use of a composition as a lamp fuel is provided, wherein the composition comprises by weight 35-45% C8 methyl esters, 25-35% C10 methyl esters, 15-25% C12 methyl esters, and/or 5-15% C14 methyl esters. Also provided is a method for producing a fuel composition comprising the steps of a) providing a vegetable oil, b) preparing alkyl esters of carboxylic acids comprised in said vegetable oil by esterification and/or transesterification, c) optionally isolating one or more of said alkyl esters of said carboxylic acids, wherein said alkyl esters of carboxylic acids comprised in said vegetable oil and/or said one or more isolated alkyl esters constitute said fuel composition.

Description

FIELD OF INVENTION[0001]The present invention relates to a non-petroleum fuel composition based on alkyl esters of a vegetable oil. The provided composition comprises a base formulation of one or more alkyl esters of a carboxylic acid, in particular, one or more alkyl esters of a C6-C16 carboxylic acid or mixtures thereof. The alkyl esters of the composition are preferably derived from renewable sources such as vegetable oil. Moreover, uses for the composition are provided as well as methods for production thereof. The composition is particularly suitable for use as lamp fuel.BACKGROUND OF INVENTION[0002]Conventional fuel compositions, such as lamp fuels are based on kerosene / paraffin or petrol. These fuel compositions suffer from the major drawback that they are highly toxic, especially upon ingestion. Even the slightest quantities of these dangerous fuels are sufficient to give heavy lung damages. Children are especially at risk, because infants often do not understand that for ex...
