A method for decomposing an asphaltene particle includes contacting the asphaltene particle with an intercalating agent; and reacting the intercalating agent to increase a distance between asphaltene molecules in the asphaltene particle to decompose the asphaltene particle. In a method for producing decomposed asphaltene, the method includes disposing an intercalating agent in an oil environment; contacting an asphaltene particle in the oil environment with the intercalating agent; reacting the intercalating agent to produce product molecules; and decomposing the asphaltene particle to produce decomposed asphaltene.
摘要:
A method for decomposing an asphaltene particle includes contacting the asphaltene particle with an intercalating agent and separating an asphaltene molecule from the asphaltene particle to decompose the asphaltene particle. Dispersing an asphaltene particle includes functionalizing the asphaltene particle and contacting the asphaltene particle with a solvent to disperse the asphaltene particle. Such asphaltene particle decomposition and dispersal can be used in a method for improving oil recovery that includes disposing a reagent in an oil environment; contacting an asphaltene particle with the reagent; decomposing the asphaltene particle to produce decomposed asphaltene; and displacing the decomposed asphaltene to improve oil recovery.
