ABSTRACT

Emulsion compositions containing substantial amounts of gilsonite consist essentially of a gilsonite phase consisting of a mixture of between about 33 and about 95% gilsonite, and a petroleum hydrocarbon having a boiling point above about 450° F., and a water phase consisting essentially of water and a small amount of emulsifying agent.

Gilsonite or Asphaltum is a natural asphalt resinous hydrocarbon found in western Iran on 1930. 

This natural asphaltite is a hard Hydrocarbon and is often called a natural asphalt, asphaltite, uintaite, or asphaltum. Gilsonite is soluble in aromatic and aliphatic solvents, as well as petroleum asphalt.

Due to its unique compatibility, Gilsonite is frequently used to harden softer petroleum products.
