Abstract
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.
