Screening test for biodiesel fuel
A colorimetric test for determining the presence or absence of biodiesel in a diesel fuel sample. The colorimetric test involves adding concentrated sulfuric acid to a sample of diesel fuel and observing any color change of the sample. A darkening of the diesel fuel sample indicates the presence of biodiesel. The degree to which the color changes after the addition of the sulfuric acid is proportional to the amount of biodiesel in the sample and therefore can be used to determine the amount of biodiesel in the sample. The reagent(s), sample containers and any necessary color scale can be provided in a kit for field testing.

Ternary fuel compositions containing biodiesel, plant oil and lower alcohols for feeding diesel-cycle motors
Fuel compositions based on biodiesel, alcohols that are not higher alcohols, and plant oil for feeding diesel-cycle motors, enabling more complete burning of fuel, lower pollutant emissions, and reduced internal impurity deposit formation on the internal surface of motors. Since the mixtures are of similar density to diesel oil, and have chemical affinity for diesel oil (due to the fact that they contain biodiesel, which performs the role of co-solvent), the present invention also contemplates compositions of quaternary mixtures, or rather, the combination of the proposed ternary mixtures (biodiesel, alcohols that are not higher alcohols, and plant oil) with petroleum diesel, in varying proportions. The preferential realization of this invention provides substitution of fuel from non-renewable sources (diesel oil) for fuels from renewable sources, which are natural, non-toxic, biodegradable and have excellent technical performance.

Cogeneration process using biodiesel as fuel and supplying energy for the production of biodiesel
A method for the production of electrical power by a diesel engine (9) connected to an alternator (10) which has biodiesel as fuel is described. The waste heat of the diesel engine is applied for the production of biodiesel.This cogeneration system contributes to the demand for so called "green" electrical and automotive energy by using fuels produced out of (waste) oils and fats of vegetable and animal origin. The carbondioxide emission in burning these fuels, is neutral to the environment.
