Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
170 words
A process for utilizing a viscous hydrocarbon as a combustible fuel for a diesel engine comprising: (a) providing a hydrocarbon in water emulsion having a hydrocarbon to water ratio of from about 60:40 to about 90:10 and a non-ionic surfactant in an amount of ≧2000 ppm, said hydrocarbon being characterized by an API gravity of ≦16° API and a viscosity of ≧100 cPs at 122° F. and said surfactant having an ethylene oxide (EO) content of ≧ about 10; (b) subjecting said hydrocarbon in water emulsion to temperature and mixing energy conditions so as to invert said hydrocarbon in water emulsion into a water in hydrocarbon emulsion characterized by a mean water drop diameter of ≦4 μm and a maximum drop diameter of ≦10 μm, wherein the temperature increases with an increase in the EO content of the surfactant and the mixing energy increases with a decrease in the hydrocarbon content; (c) atomizing said water in hydrocarbon emulsion; and (d) burning the water in hydrocarbon emulsion in a diesel engine.
Claim 2
Dependent Claim
