  • Patent number: 11291976
    Abstract: Herein disclosed are compositions for passive NOx adsorption and oxidation that include at least a manganese-based oxide and one or more promoter materials and methods for making and using said compositions. The promotor materials may include a rare earth, transition, or main group metal. The compositions may be used in NOx emission control system and adsorbs NOx compounds at low temperatures and then release NOx at higher temperatures, where the NOx can be oxidized, without the hybridized MnOX composition breaking down. The compositions are capable of maintaining a sufficiently large surface area at high temperatures found in the emissions gas streams of internal combustion engines necessary for the complete elimination of NOx.

  • Patent number: 11268160
    Abstract: Preferred embodiments of the present invention comprise the optional application of concentrations of an aqueous permanganate solution, such as an approximately 0.01% to approximately 50% liquid permanganate solution and preferably comprising approximately 20% sodium permanganate dosed at approximately 1 ppm to approximately 100 ppm to harvested sugar crops, such as sugarcane, sugar beets, and sweet sorghum, at one or more of the sugar processing steps for the crops. The steps where the liquid sodium permanganate may optionally be applied include at a sugar crop cutting step, a sugar crop conveying step, a sugar juice extraction step, a sugar juice clarifying step, and a clarifier muds filtration step.

  • Patent number: 11110497
    Abstract: There is provided according to the present invention a sustained release reactant blend and methods for making and using the sustained release reactant blends. There is further provided methods for using such blends in the in situ or ex situ remediation of contaminated groundwater and in the treatment of water and wastewater. There is further provided, according to the present invention, methods for controllably coating reactant blends whereby such coated blends exhibit sustained release properties and have an open structure.
