Abstract
The invention provides fuel mixtures containing fuel oil, glycerol, glycerol impurities and non-ionic surfactants. The mixtures remain homogeneous longer and are more chemically stable than previous mixtures. Upon combustion, the mixtures generate reduced SOx, NOx and particulate matter emissions compared to residual fuels and offer improved engine performance over previous mixtures.
Claims28
A fuel mixture comprising:
- (a) an oil in an amount from about 50% to about 99% (vol/vol) of the fuel mixture;
- (b) a plurality of droplets evenly dispersed in the oil, wherein the droplets have sizes of from about 100 nm to about 10μm;
- the droplets comprise glycerol, a combustion improver, and water;
- the combustion improver is an ether;
- the combustion improver is present in an amount less than about 10% (wt/wt) of the glycerol;
- and water is present in an amount less than about 20% (wt/wt) of the glycerol;
- and
- (c) a surfactant in an amount from about 0.1% to about 5% (wt/wt) of the fuel mixture,
- wherein the mixture remains homogeneous or chemically stable at room temperature for at least 24 hours.
