Abstract: A low viscosity, non-aging hydrocarbon in water emulsion formed from a viscous hydrocarbon comprises from about 70 to 80%/wt. oil, from about 20 to 30%/wt. water, from about 0.1 to 5.0%/wt. of an emulsifying agent, and an average oil droplet size of greater than or equal to 15 microns wherein the emulsion is characterized by a viscosity of less or equal to 1500 centipoise at 80.degree. F. and substantial non-aging over time wherein the change in viscosity of the emulsion is less than 100 centipoise per month.

Abstract: A process for upgrading heavy hydrocarbonaceous materials for making coke suitable for metallurgical purposes comprises mixing the heavy hydrocarbonaceous materials with a diluent having a closely controlled boiling range so as to facilitate transport, dehydration and desalting of the crude oil. In addition, the diluent aids in controlling temperature and residence time of the crude thereby avoiding premature decomposition.
