Abstract
A method of stabilizing a bitumen-in-water emulsion comprising contacting (i) bitumen, (ii) water, and (iii) an alkoxylated humus material to obtain a stabilized bitumen-in-water emulsion, wherein the alkoxylated humus material comprises an ethoxylated humus material, a C3+ alkoxylated humus material, or combinations thereof. A method of stabilizing a bitumen-in-water emulsion comprising contacting (i) bitumen, (ii) water, and (iii) an alkoxylated humus material to obtain a stabilized bitumen-in-water emulsion, wherein the alkoxylated humus material comprises an ethoxylated lignite, and the bitumen is extracted from the Orinoco Oil Belt in Venezuela. A stabilized bitumen-in-water emulsion comprising bitumen, water, and an alkoxylated humus material wherein the alkoxylated humus material comprises an ethoxylated humus material, a C3+ alkoxylated humus material, or combinations thereof.
