Embodiment 1

[0274] The following examples illustrate specific compositions and methods for their preparation according to the invention.

[0275] table 3

[0276]

[0277]

[0278] The composition is prepared as follows:

[0279] First, ethanol or methanol is mixed with potassium hydroxide (KOH) or sodium hydroxide (NaOH), and this mixture is then mixed with vegetable oil.

[0280] Heat the mixture to 50-60 degrees Celsius and stir. The mixture is precipitated and the glycerol fraction is separated from the fatty acid fraction of the vegetable oil. This step results in the production of methyl esters (when methanol is used) or ethyl esters (when ethanol is used).

[0281] Methyl or ethyl esters are mixed with butanol to a final concentration of 2-15% butanol. Finally, an antioxidant is optionally added to prevent premature oxidation of the composition.

Embodiment 2

[0283] Capillary transport, viscosity and flash point

[0284] Testing of Capillary Transport, Viscosity and Flash Point of Gasoline-Based Lamp Fuels and Lamp Fuels of the Invention.

[0285] The test was carried out in a Mag.Duo oil lamp with a 3mm cotton wick.

[0286]

[0287]

[0288] Tests were performed in a torch with a 10mm cotton wick.

[0289]

Embodiment 3

[0291] Preparation of biodiesel

[0292] Biodiesel can be produced from any vegetable oil as defined herein. For example, it is prepared by the following method. First, 200 mL of canola oil was added to a round bottom flask and heated to 55°C. Then, 50 mL of methanol was added together with 2.9 g of sodium hydroxide. The mixture was heated and stirred for 40 minutes, then allowed to cool to room temperature. The reaction mixture was then washed 5 times with an equal volume of DI water. Water was separated from the reaction mixture. The solution was allowed to stand in a separatory funnel for 5 hours. Glycerin (bottom) and biodiesel (upper) were separated during this time. The biodiesel is 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

technical field [0001] The present invention relates to non-petroleum fuel compositions based on alkyl esters of vegetable oils. Compositions are provided comprising one or more alkyl esters of carboxylic acids, in particular, C 6 -C 16 A base formulation of one or more alkyl esters of carboxylic acids or mixtures thereof. The alkyl esters of the composition are preferably derived from renewable resources such as vegetable oils. Furthermore, the use of said composition and its preparation method are provided. The compositions are particularly suitable for use as lamp fuels. Background technique [0002] Conventional fuel compositions such as lamp fuels are based on kerosene / paraffin or gasoline. The main disadvantage suffered by these fuel compositions is their high toxicity, especially after ingestion. Even the tiniest amount of these dangerous fuels is enough to cause serious lung damage. Children are especially at risk because babies are often unaware that, for exa...
