  • Publication number: 20010005955
    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.
