Abstract:
A gas purification getter for purifying a gas. The getter includes a canister having a cylinder body including a corrugated wall, an inlet end cap coupled to an inlet end of the cylinder body and an outlet end cap coupled to an outlet end of the cylinder body so that the cylinder body, the inlet end cap and the outlet end cap define a sealed chamber. The getter also includes a powder bed of a getter material provided within the chamber so that a flow of the gas from the inlet end to the outlet end is purified by the getter material. Voids in the powder bed when the canister is horizontally oriented are limited to raised portions in the corrugated wall so that there is no short circuit path for the gas to flow from the inlet end to the outlet end.
Abstract:
The present disclosure relates to a substrate containing passive NOx adsorption (PNA) materials for treatment of gases, and washcoats for use in preparing such a substrate. Also provided are methods of preparation of the PNA materials, as well as methods of preparation of the substrate containing the PNA materials. More specifically, the present disclosure relates to a coated substrate containing PNA materials for PNA systems, useful in the treatment of exhaust gases. Also disclosed are exhaust treatment systems, and vehicles, such as diesel or gasoline vehicles, particularly light-duty diesel or gasoline vehicles, using catalytic converters and exhaust treatment systems using the coated substrates.
Abstract:
Systems and methods for treating a fluid with a body are disclosed. Various aspects involve treating a fluid with a porous body. In select embodiments, a body comprises ash particles, and the ash particles used to form the body may be selected based on their providing one or more desired properties for a given treatment. Various bodies provide for the reaction and/or removal of a substance in a fluid, often using a porous body comprised of ash particles. Computer-operable methods for matching a source material to an application are disclosed. Certain aspects feature a porous body comprised of ash particles, the ash particles have a particle size distribution and interparticle connectivity that creates a plurality of pores having a pore size distribution and pore connectivity, and the pore size distribution and pore connectivity are such that a first fluid may substantially penetrate the pores.
Abstract:
Rare earth metal compounds, particularly lanthanum, cerium, and yttrium, are formed as porous particles and are effective in binding metals, metal ions, and phosphate. A method of making the particles and a method of using the particles is disclosed. The particles may be used in the gastrointestinal tract or the bloodstream to remove phosphate or to treat hyperphosphatemia in mammals. The particles may also be used to remove metals from fluids such as water.
Abstract:
An acid gas sorbent composition is disclosed. The composition comprises a compound having the following formula: (SiO2)x(OH)y F.B wherein F optionally exists and said F is at least one of the following: a functionalized organosilane, a sulfur-containing organosilane, or an amine-containing organosilane; and wherein B is a hygroscopic solid at a preferred water to solid molar ratio of about 0.1 to about 6, and more particularly, B is a basic inorganic solid including, but not limiting to, alkali or alkali-earth metal oxides, hydroxides, carbonates, or bicarbonates, containing at least one of the following metal cations: calcium, magnesium, strontium, barium, sodium, lithium, potassium, cesium, lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, dysprosium, scandium, ytterbium, yttrium, or erbium; wherein the molar ratio of y/x is equal to about 0.01 to about 0.5.
Abstract:
An adsorption method adsorbs a substance by using a tube-shaped apatite crystal. The apatite crystal may be a monocrystal given by a general formula M25(PO4)3X (M2 denotes at least one element selected from the group consisting of divalent alkali earth metal and Eu, and X denotes at least one element or molecule selected from the group consisting of halogen element and OH). The outer form of the apatite crystal may be a hexagonal prism in which the aperture of a hole formed on a top surface or bottom surface of the hexagonal prism may be hexagonal.
Abstract:
A getter device containing a combination of getter materials is described. The device has a mixture of cerium oxide, copper oxide and metallic palladium for the removal of hydrogen and carbon monoxide in vacuum applications, particularly suitable to be used in vacuum insulation applications. This combination of getter materials is preferably added to powders of other getter materials such as alkali metals hydroxides and desiccant materials that are effective for maintaining the vacuum in thermal insulation systems.
Abstract:
A water treatment composition includes a water soluble film formed into a sealed pouch. The pouch contains a composite of a phosphate removing substance, a polymer flocculant, or an enzyme, or any combination. The phosphate removing substance, the polymer flocculant, and the enzyme are bound to each other within the composite. The pouch is added to a body of water. The pouch dissolves to release the compounds and treat the water.
