Benefits of technology

The invention is a new biofuel composition that can be used in various fuel-related applications. It is made up of glycerine, water, and at least one alcohol. The alcohol can be ethanol or glycol. The composition has a specific viscosity and flash point, and can be used as a direct fuel, a component of a biofuel blend, a fuel additive, or to generate power or electricity. The method of making the biofuel involves mixing the components together. The biofuel composition can be used in combination with liquid fuels like diesel, biodiesel, gasoline, pyrolysis oil, vegetable oil, oil from animal fat, synthetic oil, non-synthetic oil, or waste oil. The amount of biofuel in the biofuel composition can range from 1% to 99% of the total weight of the biofuel.

Problems solved by technology

In fact, due to current economic conditions, the capacity utilization at many of these facilities is extremely low.
At this high viscosity, glycerin cannot be readily atomized and therefore cannot be readily used as a neat fuel.
However, such technologies are not completely effective, particularly with respect to removal of methanol.
Difficulties in refining crude glycerin can be further exacerbated by variations in content of impurities.
This variability can present challenges to the production of refined glycerin product having consistently uniform quality relative to desire levels of purification or customer quality specifications.
The known chemical-physical processes used to purify crude glycerin for use in those markets are expensive.
They can increase the cost of the final product by 2.5 to 3 times the initial cost of the feedstock and do not serve to address and the problems presented by the viscosity, PP, FF or energy content of glycerin.
However, use of this burner would require new equipment as opposed to the use of already existing combustion systems or burners.

[0048]A sample biofuel composition was prepared by mixing the three components in the following weight percent: glycerin 70 wt %, water 20 wt %, cda ethanol 10 wt %. A one pound sample was prepared with each ingredient being measured and provided in weight amount corresponding to their respective weight percent. The glycerine was placed in a large beaker. The water and cda alcohol were mixed together in another beaker and then poured into the beaker of glycerine. The components were mixed for approximately 3 minutes to produce the biofuel composition. The Kinematic Viscosity @ 104° F. / 40° C. of this biofuel was reported 10.31 cSt, the Heat of Combustion by Bomb calorimeter Gross BT-LB was reported 5,835 btu / lb and the specific gravity @15.5° / 60° F. was reported 1.142.

[0049]A sample biofuel composition was prepared by mixing the three components in the following weight percent: glycerin 70 wt %, water 20 wt %, ethylene glycol 10 wt %. A one pound sample was prepared with each ingredient being measured and provided in weight amount corresponding to their respective weight percent. The glycerine was placed in a large beaker. The water and ethylene glycol were mixed together in another beaker and then poured into the beaker of glycerine. The components were mixed for approximately 3 minutes to produce the biofuel composition. The Kinematic Viscosity @ 104° F. / 40° C. of this biofuel was reported 12.66 cSt, the Heat of Combustion by Bomb calorimeter Gross BTU-LB was reported 5,508 btu / lb.

[0050]The fuel composition of Example 1 has a flash point>110° C. (230° F.), well above the required FP for marine fuels and a pour point much improved over that of glycerine alone. The fuel compositions of Example 2 and of Example 3 have viscosities below 15 cSt. Vis...

Abstract

Biofuel compositions and methods. Biofuel compositions comprised of glycerine, water and one or more alcohols can be prepared and utilized as an alternative or renewable fuel or mixed with other fuels and fuel products. The methods of preparation require simple mixing as the biofuel composition is a solution. The components can be mixed in any sequence. By varying the amount of water and / or alcohol mixed with the glycerine allows for preparation of biofuel compositions having consistent or uniform properties, such as pour point and / or flashpoint even using glycerine from different sources and having different specifications.

Description

RELATED APPLICATION[0001]The present application claims priority to U.S. Provisional Application No. 61 / 347,940 filed May 25, 2010, the teachings of which are incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relates to biofuel compositions and methods of making biofuel compositions. More particularly, the present invention relates to glycerine-based biofuel compositions useful as an alternative fuel or as a fuel additive.BACKGROUND OF THE INVENTION[0003]Currently, there is significant interest in and efforts to develop renewable fuel compositions, supplements and additives as alternatives to those derived from petroleum, such as gasoline, diesel fuel and the like. There has also been interest in developing renewable fuels that can be co-fired with other fuel sources such as coal, biomass or those derived from biomass.[0004]One alternative that has been developed is biodiesel. Biodiesel is made utilizing the chemical reaction known as transesterification. I...
