Abstract
Biodiesel is formed by blending an with a hydrocarbon fuel, preferably #2 diesel, gasoline, or kerosene. Water in the mixture, and other impurities, are removed by adding a coalescing aid such as naphtha, xylene or naphthalene and passing the mixture through a series of filters including a coalescing filter. Optional components that can be added to the fuel include cetane additives, lubricants such as trimethylbenzene and ethylene, as well as performance enhancers such as acetone.
Claims15
A method of forming biodiesel comprising blending oil with a hydrocarbon fuel to form a fuel mixture having a water content;
- adding to said fuel mixture a hydrocarbon coalescing aid;
- and
- filtering water from said fuel mixture.
A method of forming a biodiesel composition comprising blending a triglyceride composition with a hydrocarbon fuel selected from the group consisting of diesel fuel, gasoline, kerosene, and mixtures thereof, to form a fuel mixture;
- establishing a water content in said fuel mixture of at least 0.4 ounces of water per gallon of fuel mixture;
- adding to said fuel mixture a coalescing aid selected from the group consisting of naphtha, xylene, naphthalene, toluene, and mixtures thereof in an amount equal to at least about 0.25 oz/gal of said fuel mixture;
- and
- removing water from said fuel mixture with a coalescing filter.
A biodiesel fuel composition comprising at least about 75% by weight of a triglyceride, at least 12% by weight of a hydrocarbon fuel, and about at least 0.25 oz/gal coalescing aid selected from the group consisting of naphthalene, xylene, naphtha, toluene and mixtures thereof, a cetane additive, and a lubricant selected from the group consisting of trimethylbenzene, ethylene and mixtures thereof.
