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.

A fuel mixture comprising:
- (a) an oil selected from the group consisting of marine gas oil, marine diesel oil, intermediate fuel oil, low sulfur diesel, ultra-low sulfur diesel and residual fuel oil;
- (b) glycerol;
- and
- (c) a non-ionic surfactant,
- wherein the mixture remains homogeneous or chemically stable at room temperature for at least 24 hours.
