    Abstract: The present disclosure relates generally to methods and systems for achieving enhanced catalytic performance via the strategic arrangement of multiple catalyst beds in series, where each catalyst bed comprises a compositionally-distinct catalyst, and each catalyst facilitates the conversion of the same structural moieties on the reactant to form the same product. Arranging multiple catalyst beds according to the methods and systems disclosed herein allows a predictable enhancement of conversion of the reactant to product without the need for time-consuming experimentation to test all possible catalysts configurations.

    Abstract: The invention relates to a catalytic hydrocracker with two different catalyst beds within the reactor where each is loaded with a catalyst that has different hydrocracking properties. A first catalyst bed preferably cracks heavy oil more aggressively than the catalyst in the second bed. The catalytic hydrocracker includes further two recycle lines such that one directs unconverted oil through both hydrocracker beds and a bypass inlet is positioned between the first and second catalyst beds to admit unconverted oil to pass only through the second less aggressive hydrocracker catalyst bed. When gasoline prices favor the production of gasoline, less unconverted oil is recycled through the bypass therefore making more gasoline, but when prices favor the production of jet and diesel, more recycle is directed through the bypass recycle thus making less gasoline and more diesel and jet fuel.

    Abstract: Carbon particles are coated with a water-soluble carbon residue material by oxidizing the carbon residue in water and forming a solid coating on the particles. The coated particles may be heated to graphite forming temperatures to prepare the coated particles for use an anode powder for a battery.

    Abstract: A redox flow battery is described that does not include an ion exchange resin such as a proton exchange membrane but rather uses a generally stationary separator liquid that separates the anolyte from the catholyte at immiscible liquid-liquid interfaces. Solvents and electrochemically active components of the anolyte and catholyte would not cross the liquid-liquid interfaces between the separator liquid and the anolyte and catholyte, but certain ions in each of the anolyte and catholyte would cross the interface during charging and discharging of the redox flow battery. The separator liquid comprises a relatively small total volume of liquid in such a flow battery arrangement as compared to the anolyte and catholyte. Suitable chemical options are described along with system options for utilizing immiscible phases.

    Abstract: The invention relates to blocking fraudulent gathering of credit card and debit card information during a legitimate payment transaction at a credit/debit card reader. The invention includes the installation, preferably in a non-uniform manner, of blockers onto one or more faces or surfaces of the card reader. Properly installed blockers will tend to prevent the easy installation of a flush mounted skimmer device that is designed to overlay the legitimate card reader at a store or point of sale location such as a gasoline pump.

    Abstract: The present disclosure relates generally to systems operable to produce liquid transportation fuels by converting a hydrocarbon feed stream that comprises both isopentane and n-pentane, and optionally, some C6+ hydrocarbons. The system separates the hydrocarbon feed stream to form a first fraction comprising isopentane and smaller hydrocarbons, and a second fraction comprising n-pentane and larger components of the hydrocarbon feeds stream. Each fraction is then catalytically-activated in a separate activation reactor containing a separate activation catalyst, where the conditions maintained in each reactor are selected to maximize the conversion of each fraction to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. In certain embodiments, the first activation reactor is maintained at a lower temperature than the second activation reactor. Certain embodiments of the system mix at least a portion of the effluents from the first and second activation reactor and convert the resulting mixed effluent in either an oligomerization reactor containing an oligomerization catalyst or an oligomerization reactor containing an alkylation catalyst to provide enhanced yields of upgraded hydrocarbon products that are characterized as a liquid transportation fuel or a blend component thereof.
