A fuel composition comprising a hydrocarbon in water colloidal dispersion including spherical hydrocarbon particles having a mean softening point exceeding about 95.degree. C., and a water soluble dispersion agent comprising a surfactant and stabilizer. The process for the production thereof is disclosed. These dispersions have a median particle size below about 4.5 microns and about 90% of the particles have a mean particle size diameter less than about 60 microns. These dispersions are storage stable, stable towards transportation, and can be pumped and passed through a burner apparatus without destabilizing.

[ What is claimed is:] [1.] A continuous process for preparing a fuel composition comprising a colloidal dispersion of high softening point hydrocarbon particles in water comprising:(a) initiating and maintaining the flow of an aqueous solution of a dispersion agent having a temperature from about 80.degree. C. to the boiling point of the solution through a high shearing action mixing device;(b) introducing melted normal asphalt into said mixing device with said dispersion agent and mixing said melted normal asphalt with said dispersion agent in said mixing device so as to create an asphalt emulsion and removing said asphalt emulsion from said mixing device;(c) creating a pressure at said outlet of said mixing device in excess of the vapor pressure of the emulsion;(d) ceasing the introduction of said normal asphalt into said mixing device and in lieu thereof introduce hydrocarbons having a mean softening point in colloidal aqueous dispersion exceeding about 95.degree. C. and heated above a temperature of about 200.degree. C. into said mixing device with said aqueous solution of dispersion agent at a high rate of shear sufficient to produce highly dispersed hydrocarbon particles in water having a median particle diameter below about 4.5 microns and about 90% of the particles being below about 60 microns;(e) mixing said heated hydrocarbons with said aqueous solution of dispersion agent and maintaining the mixture at a temperature of between from about 120.degree. C. to about 170.degree. C., so as to form a colloidal dispersion comprising petroleum hydrocarbon particles;(f) cooling said dispersion to a temperature below about 90.degree. C.; and(g) reducing the pressure to atmospheric.
