International Classification:

C10L 132

US Classification:

44301, 44302, 44325, 44326, 44331, 44386

Abstract:

A process to make water-blended fuel by emulsifying the emulsifier in a portion of the fuel, then adding the water under high shear mixing to give a concentrated water fuel emulsion. The concentrated emulsion is then diluted with final portion of fuel using mixing or blending conditions resulting in an emulsified water blend fuel.

Abstract:

The invention relates to a novel emulsified composition containing (a) major amount of an aqueous phase, (b) a minor amount of an organic phase (c) a thickener and (d) a minor but effective amount of at least one emulsifier to emulsify the aqueous and organic phase resulting in a water in oil emulsifeid composition, in particular emulsified greases and emulsified coatings. Further, the present invention provides a process for making the emulsified composition.
