摘要： A redox flow battery and a method of operating a redox flow battery. The redox flow battery includes an ionically conductive separator, a working side flowing electrolyte, a working electrode, a counter electrode, and an auxiliary electrode. The auxiliary electrode is in ionic contact with the working electrode, where an electrically insulating peripheral gap separates the auxiliary electrode from the working electrode. An auxiliary power source is configured to establish an auxiliary circuit voltage differential between a terminal in each of the counter electrode and the auxiliary electrode to control an auxiliary electrode voltage such that the auxiliary electrode voltage is within an electrochemical window of the working side flowing electrolyte, as well as to establish a voltage differential between the working electrode terminal and the auxiliary electrode terminal.

摘要： Methods of extracting 1-4 cycle heterocyclic compounds and 2-5 cycle polynuclear aromatic hydrocarbons from a hydrocarbon feedstock are described. The methods include providing a hydrocarbon feedstock containing crude oil fractions, and determining an A/R ratio and an asphaltene concentration of the hydrocarbon feedstock. Based upon the A/R ratio and the asphaltene concentration, the treatable hydrocarbon feedstock undergoes one or more of cracking and fractionating. Subsequently, at least one targeted portion of the heterocyclic compounds is extracted from the fractionated stream with an aqueous solvent. A stream containing the 2-5 cycle polynuclear aromatic hydrocarbons is transferred to an extractor and the 2-5 cycle polynuclear aromatic hydrocarbons are extracted with a solvent system comprising an aprotic solvent.

摘要： Embodiments of this disclosure are directed to a parking indicator comprising a vehicle contact body, a pivoting contact body support, an elongated visibility indicator, an indicator actuating mechanism, and an indicator retracting mechanism. The pivoting contact body support is attached to the vehicle contact body and is configured to permit the vehicle contact body to pivot to a horizontally-oriented position when the vehicle contact body is grounded via the pivoting contact body support and is contacted by a vehicle entering a parking space occupied by the parking indicator. The elongated visibility indicator is mechanically coupled to the vehicle contact body via the indicator actuating mechanism such that the indicator actuating mechanism upholds the elongated visibility indicator in an extended position. The indicator retracting mechanism is configured to retract the elongated visibility indicator to a retracted position when the vehicle contact body pivots from the vertically-oriented position to the horizontally-oriented position.
