  • Patent number: 8557101
    Abstract: This invention relates to a process for electrochemical conversion of dibenzothiophene type molecules of petroleum feedstreams selectively to mercaptan compounds that can then be more easily removed from the electrochemically treated product stream by either caustic extraction or thermal decomposition of the thiol functionality to hydrogen sulfide. The conversion of dibenzothiophenes to mercaptans is performed by electrochemical means in the substantial absence of hydrogen and in the substantial absence of water.

  • Publication number: 20120199494
    Abstract: A self-contained system which promotes the multiplication of algae from either salt water or fresh water sources as a feedstock. This process inspires a direct output of lipids for bio-diesel fuel as well as a significant raw algae yield which can be further processed into additional bio-fuel as well as other valuable resources. In addition to inspiring a direct output of algal lipids for bio-diesel, the system generates massive raw algae biomass output that can be directly utilized as an agent for efficiently cleaning up oil spills.

  • Patent number: 8133382
    Abstract: An electrocoagulation treatment device includes a plurality of spaced reaction plates disposed within a reaction chamber. A voltage is applied to selected reaction plates to create an electrical field within the electrocoagulation chamber. The plates are arranged vertically which induces a vertical flow of liquid through a device. The device includes various embodiments adapted for use as a large industrial unit, a portable unit or for use within the home. The voltage and amperage of the electrical field chamber may be adjusted by placing selected reaction plates in electrical contact with the voltage source.

  • Patent number: 6218556
    Abstract: An electrochemical process for hydrogenating an unsaturated fatty acid, mixtures of two or more fatty acids, or the unsaturated fatty acid constituents of an edible or non-edible oil's triglycerides is performed using a solid polymer electrolyte reactor. Membrane electrode assemblies consist of a cation exchange membrane onto which porous anode and cathode electrodes are attached. As the electrodes are permeable, reactant and products enter and leave the membrane/cathode and membrane/anode reaction zones via the back sides of the electrodes. Hydrogen is generated in situ by the electro-reduction of protons that are formed at the anode and which migrate through the ion exchange membrane for reaction with the fifty acids or fatty acid constituents. In the disclosed process, only protons (H+ ions) carry the current between the anode and the cathode. The need for a supporting electrolyte to conduct electricity has been circumvented.

  • Patent number: 5843301
    Abstract: A process and system for converting petroleum residue ("resid") into a liquid product and a solid product. The resid is first mixed with a solvent having a generally nonpolar molecular character. A strong electric field is then applied to the mixture to agglomerate the asphaltenes and other large molecules in the resid. The agglomerates are then separated from the remaining liquid, thereby producing liquid and solid products. The liquid product is useful as a feedstock for petrochemicals and transportation fuels, and the solid product is suitable for combustion as a coal substitute. A portion of the liquid product may be recycled as the solvent.
