Abstract

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 200° F., and a water phase consisting essentially of water and a small amount of emulsifying agent. The emulsifying agent may include a surface active clay.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 67 words
An emulsion composition consisting essentially of (a) 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 200° F., and (b) a water phase consisting essentially of water and between about 0.05 and about 10% of an emulsifying agent, and wherein the gilsonite:water phase ratio is between about 1:2 and 3:1, respectively.
Claim 2
Dependent Claim 67 words
An emulsion composition consisting essentially of (a) 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 200° F., and (b) a water phase consisting essentially of water and between about 0.05 and about 10% of an emulsifying agent, and wherein the gilsonite:water phase ratio is between about 1:2 and 3:1, respectively.
Claim 3
Dependent Claim 23 words
The composition of claim 1 wherein the amount of gilsonite is between about 25 and about 75% by weight of the total composition.
Claim 4
Dependent Claim 13 words
The composition of claim 2 wherein said emulsifying agent is cationic or anionic.
Claim 5
Dependent Claim 18 words
The composition of claim 1 wherein said emulsifying agent comprises up to about 10% bentonite clay, by weight.
Claim 6
Dependent Claim 21 words

Claim 9
Dependent Claim 31 words
A composition of claim 1 wherein said emulsifying agent comprises between about 0.05 and about 5% of an emulsifying agent selected from the group consisting of cationic, anionic and non-ionic emulsifiers.
Claim 10
Dependent Claim 23 words
A composition of claim 8 wherein said emulsifying agent includes a surface active clay comprising up to about 10% of the total composition.
Claim 11
Dependent Claim 40 words
A composition of claim 4 wherein said emulsifying agent includes a surface active clay selected from the group consisting of kaoline, kaolinite, halloysite, pyrophyllite, serpentine, chrysotile, talc, and mixtures thereof and comprising up to about 90% of the bentonite clay.
Claim 12
Dependent Claim 22 words
The composition of claim 1 wherein the petroleum hydrocarbon is selected from the group consisting of naphtha, gasoline, kerosene, and mixtures thereof.
