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