  • Patent number: 11904959
    Abstract: Systems and methods are provided for detecting water within an electronic power steering assembly. A sensor assembly includes a resistor and a water-sensitive capacitor arranged to provide a series resistor-capacitor (RC) network having a cut-off frequency that is a function of a capacitance of the water-sensitive capacitor. An oscillator provides an excitation to the series RC network having a known frequency, such that the series RC network provides an output in response to the excitation. An envelope detector receives the output of the series RC network and generates an output representing an amplitude of the output of the series RC network. A microcontroller determines if water is present within the electronic power steering assembly from the amplitude of the output of the series RC network.

  • Patent number: 9845271
    Abstract: A catalyst system and a process for methanol to light olefin conversion with enhanced selectivity towards propylene. The catalyst system comprises a honeycomb monolith catalyst support coated with aluminosilicate nanozeolite catalysts on the edges and inside the channels of the support structure. The aluminosilicate nanozeolite catalysts have not been pre-modified with a promoter metal. The catalyst system gives higher hydrothermal stability to the catalyst compared to randomly packed pellet catalysts and allows methanol to be converted to predominantly propylene at a low temperature, with decreased selectivity towards C2, higher olefins and paraffinic hydrocarbons.

  • Patent number: 9505635
    Abstract: The wastewater filtration system and method relates to systems and methods that use Ruba Al-Khali Saudi sand as the filtration media in systems for treating industrial wastewater. Ruba Al-Khali Saudi sand is effective in removing organic dyes, particularly rhodamine B, from the wastewater. The method includes bringing wastewater having an organic dye constituent into contact with the Saudi sand for a period of time sufficient to adsorb the organic dye. The system may include a batch reactor, such as a fixed bed or moving bed reactor, or a continuous flow reactor, such as a column reactor. When a batch reactor is used, the method may benefit from shaking or agitating the filtration media, particularly in the dark or under low ambient light conditions. The method may include regenerating the Saudi sand after use by heating the filtration media.

  • Publication number: 20150174567
    Abstract: The hybrid photocatalyst for wastewater remediation is a composite of rhodamine B and BiOBr. The rhodamine B has a concentration between about 0.1 wt % and about 1 wt % of the overall photocatalyst. The hybrid photocatalyst is made by immersing a BiOBr semiconductor in an aqueous rhodamine B solution to form the hybrid photocatalyst by sorption of the rhodamine B by the BiOBr semiconductor. In use, the hybrid photocatalyst is added to wastewater containing at least one contaminant, such as methyl orange (sodium 4-[(4-dimethylamino)phenyldiazenyl]benzenesulfonate), to form a suspension of the hybrid photocatalyst and the at least one contaminant. The suspension is then exposed to visible to light to form a slurry containing a reaction mixture in the wastewater. The slurry is then filtered to remove the reaction mixture.

  • Patent number: 8785340
    Abstract: The catalyst exhibiting hydrogen spillover effect relates to the composition of a catalyst exhibiting hydrogen spillover effect and to a process for preparing the catalyst. The catalyst has a reduced transition base metal of Group VIB or Group VIIIB, such as cobalt, nickel, molybdenum or tungsten, supported on a high porous carrier, such as saponite, the base metal being ion-exchanged with at least one precious metal of Group VIIIB. The process includes the steps of loading the base metal onto the support, reducing the base metal, preferably with H2 at 600° C., and thereafter ion-exchanging the precious metal with the base metal. Preferred examples of the catalyst include a saponite support loaded with about 10-20 wt % cobalt and about 0.1-1 wt % precious metal. The catalyst is optimized for reactions that occur in commercial processes at about 360-400° C., such as in hydrocracking.

  • Publication number: 20110011728
    Abstract: The system and method for conversion of molecular weights of fluids includes an elongate metallic pipe. A fluid is caused to flow through the pipe. A center electrode is mounted within the pipe coaxially with the pipe axis and the flow direction, the electrode being insulated from the pipe wall. The center electrode and the pipe wall are connected to the terminals of a voltage source to create an electric field extending radially between the center electrode and the pipe wall. A source of gamma radiation positioned either within the center electrode or external to the pipe directs gamma rays transverse to the direction of fluid flow. The combined radiation and electric field disrupts chemical bonds, creating ionization zones and resulting in the formation of lower-molecular-weight compounds. Optionally, a magnetic field may be superimposed in the direction of fluid flow.
