Abstract:
A treatment media, system, and method are disclosed which combines adsorptive capacity of a carbon media (e.g., biochar) with chemical treatment characteristics of a red mud substance, e.g., to remove metals and/or other contaminants from waters. The treatment media may also improve biological conditions of affected soils. In an example treatment method, a lignin based material is thermo-chemically decomposed to have a large weight fraction of carbon (e.g., the biochar), and an ore is processed to yield aluminum oxide comprising a variety of iron oxides and having high alkalinity in slurry (e.g., the red mud). The thermo-chemically decomposed lignin based material is combined with the mud material.
Abstract:
A process for capturing sulphur impurities present in gas feeds containing H2 and/or CO: a. desulphurization with a retaining material containing an active phase, b. optionally, rendering the sulphurized retaining material inert, c. oxidative regeneration of the retaining material, d. optionally, rendering the regenerated retaining material inert, and e. desulphurization with the retaining material that has been regenerated and rendered inert, and regenerating the retaining material.
Abstract:
A method of sorbent dialysis is provided for enhanced removal of uremic toxins, such as toxic anions and/or organic solutes, from spent dialysate. More highly adsorbable zirconium polymeric complexes of these anions and/or organic solutes can be initially formed in spent dialysate by treatment with zirconium salt solution or other zirconium cation source, and then removed with adsorbent to provide purified or regenerated dialysate. Sorbent dialysis systems for detoxifying spent dialysate containing toxic anions and organic solutes are also provided.
Abstract:
A composition for capturing, removing, and in some cases recovering a pollutant or raw material wherein the composition includes a polymeric material, one or more metal or nonmetal materials in granular form, and preferably a small amount of a salt material.
Abstract:
The invention relates to methods for regenerating a used sorbent having a gas adsorbate adsorbed thereto. In particular, the used sorbent comprises liquid marbles. The liquid in the liquid marbles is comprised of a material or mixture of materials that selectively removes unwanted gaseous component in the gas to be purified.
Abstract:
Provided is a recovery method of useful resources in seawater and brine, and more particularly, a recovery method of useful resources in seawater and brine capable of improving adsorption efficiency and recovery efficiency of trace amounts of useful resources such as strontium, lithium, boron, or the like, present in brine at low cost by using a magnetic adsorbent composite and a solid-liquid separation process which uses magnetic force.
Abstract:
A CO2 removal device includes: a CO2 capturing material which captures H2O and CO2 in a gas; a reaction container which contains the CO2 capturing material; an H2O measuring unit for measuring the concentration of H2O in the gas; an H2O concentration adjustment device which adjusts the concentration of H2O on the basis of information obtained by the H2O measuring unit; a gas introduction path introducing the gas into the reaction container from the H2O concentration adjustment device and bringing the gas into contact with the CO2 capturing material; a first gas discharge path discharging the gas from the reaction container after the gas has been brought into contact with the CO2 capturing material; and a second gas discharge path discharging the gas that has been desorbed from the CO2 capturing material from the reaction container. The CO2 removal device allows for the reduction of energy consumption in removing CO2.
Abstract:
A sorptive-filtration system for removing at least one of negatively or positively charged ions, complexes or particulates from an aqueous stream. The system includes a) flow formed substantially from at least one of rainfall-runoff or snowmelt-runoff; b) a filter containment communicating with the runoff stream such that at least part of the stream passes through the filter containment; and c) a granular filter media disposed within the filter containment, the filter media having an amphoteric material applied thereto, wherein the amphoteric material comprises a metal selected from at least one of Fe, Al, Mn, or Si.
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:
A composition for packaging an electronic device comprises a matrix and an adsorption material having a water vapor adsorption capability, and the adsorption material includes attapulgite and/or zeolite. By adding attapulgite and/or zeolite which have an adsorption effect to modify the formulation of the frit, the compositions for packaging an electronic device can effectively reduce the influence of water vapor on the electronic device, thereby effectively extending the lifetime of the packaged electronic device.
