  • Hydrophobic compound emulsions free of silicon and fluorine for an oil recovering method that modifies the wettability of rocks from hydrophilic to oleophilic
    Patent number: 10329474
    Abstract: An oil recovery method by the modification of the rock wettability from hydrophilic to oleophilic using hydrophobic compounds. Specifically, the method relates to the application of oil-type emulsions in water based on hydrophobic compounds free of silicon and fluorine to increase the oil recovery in mature sandstone-type reservoirs after the injection of water.
    Type: Grant

  • Ionic liquid catalyst for the improvement of heavy crude and vacuum residues
    Publication number: 20120318714
    Abstract: Heavy crude oil residue and vacuum residue is upgraded using an ionic liquid catalyst formulated with metals of Group VIB and VIIIB of the periodic table, which catalyst is highly miscible in the hydrocarbon phase. The combination of different metals and acidity from the protons that make up the ionic liquid breaks the links C—S, C—N and C—O of the resins and asphaltenes and increases API gravity, decreases viscosity, removes sulfur and nitrogen compounds, and results in conversion of 50 to 70% of the waste oil and heavy crude oil into lighter distillates.
