  • Patent number: 10047300
    Abstract: A novel process for metal content reduction of hydrocarbon oil is disclosed, which is primarily aimed at reduction of vanadium and nickel. The process uses electricity to accelerate the demetallation process, but only the flow of electrons of the electric current is used to expedite the reaction, instead of the electrolysis effect of the electric current. The process is carried out by adding inter-phase surface active reagent and phase transfer catalyst at a relatively low temperature range of 80 to 200° C. and achieves metal content reduction for vanadium and nickel. Aqueous phase alcoholic derivatives of amine solution is treated with hydrogen sulfide, carbon dioxide, etc. by additive reaction to render it more suitable for carrying more electric current and make them more active for metal reduction.

  • Patent number: 9861950
    Abstract: The activation of the C—H bond using low temperature plasma with an inlet liquid stream such that value added products are formed effectively. An organic liquid (e.g., hexane which is immiscible with liquid water) is injected into a flowing gas (argon) stream followed by mixing with a liquid water stream. Thereafter, the mixture contacts a plasma region formed by a pulsed electric discharge. The plasma formed with the flowing liquid and gas between the two electrodes causes chemical reactions that generate various compounds.

  • Patent number: 9837611
    Abstract: Design and use of photo-switching, fullerene-based dyads of the design x-D-y-A or D-y-A-x as interfacial layers (IFL) for organic photovoltaic (OPV) devices are described herein. The fullerene-based dyads and triads of the present invention contain electron-donating substituents such as porphyrins or phthalocyanines that exhibit charge separation states with long lifetimes upon irradiation, resulting in rejection of electrons reaching the electrode and concurrently promoting the conduction of holes. This phenomenon has a strong rectifying effect on the whole device, not just the interfaces, resulting in improved charge extraction from the interior of the photo-active layer. The invention further describes anchoring an IFL to the ITO surface as a monolayer, bilayer, or greater multilayers. One OPV design embodiment of the present invention embodiment involves the formation of covalent bonds via silane groups (—SiR3) as the anchor (x), to form siloxane bonds.
