The invention relates to the field of cleaning the environment, and more particularly to a sorbent material for collecting petroleum and petroleum products, and to a method of producing the same. The method includes saturating a basalt fiber canvas with a hydrophobizing liquid and subsequently drying the same, wherein the basalt fibers of the canvas have a diameter of 0.2-2 microns and a density not exceeding 20-25 kg/m.sup.3; prior to saturation, the canvas is first fluffed using compressed air until a density of 12-15 kg/m.sup.3 is reached; the saturation using a hydrophobizing liquid is performed by introducing the hydrophobizing liquid into the pre-fluffed basalt fibers of the canvas in the form of aerosol particles via compressed air; and the subsequent drying of the saturated canvas is performed using compressed air, preferably at a temperature of 65 C.-75 C. The technical effect of invention is a simplified method with a broader field of application. The material manufactured in accordance with this method is characterized in that the volume of hydrophobizing additive is selected in order to achieve a density of the finished material which is in the range of 10-70 kg/m.sup.3, or in the range of 10-15 kg/m.sup.3, in the range of 30-70 kg/m.sup.3. This improves the sorbent characteristics of the material.

Provided are a high-performance desulfurizing agent for gases and a gas desulfurization method that provide a high desulfurization performance even at low temperatures and can maintain its desulfurization performance for a long period of time. The desulfurizing agent is characterized in that it includes a zinc oxide, an aluminum oxide and copper, the agent further including nickel by from 1.0 mass % to 10 mass % and ruthenium by from 0.1 mass % to 1.0 mass %. The gas desulfurization method is characterized in that the desulfurizing agent is brought into contact with the gas in the coexistent of hydrogen, thus decomposing/removing sulfur compound contained in the gas.

The subject invention provides systems and methods for capturing carbon dioxide in a cyclic process of mechano-chemical reactions. The subject invention also provides systems and methods for synthesizing siderite, by means of mechano-chemical reactions, using mill rotation. Siderite acts as an efficient reversible sorbent and can be decomposed, generating magnetite, carbon and/or metallic iron as well as pure carbon dioxide. Said systems and methods employing carbon dioxide capture/release reactions in the carbonation-calcination cycles are suitable for using in any iron, steel and non-steel industries to reduce carbon dioxide emissions into the atmosphere.

Disclosed are methods of making a porous particle material for use as stationary media and related chromatographic separation devices utilizing the disclosed stationary media. The porous particle material has a reduced pore volume which yields improved stability and column lifetime, and additionally has a surface coating, resulting in a surface modified porous particle material that minimizes unwanted adsorption interactions with samples to be tested

Methods and devices are disclosed for the treatment of a subject suffering from drug intoxication by cleansing a contaminated sample from the subject with adsorption media. The adsorption media composition is selected for its antithrombogenic properties and for its ability to adhere to one or more drug targets to be reduced or eliminated. The media can further be held in a cartridge for use in extracorporeal treatments such as those of hemoperfusion. Contacting the contaminated sample from the subject with the absorption medium allows for the separation of a portion of the drug target from the sample, producing a cleansed sample that can be infused into the subject.

This invention generally relates to a process for manufacturing a lithium selective adsorption/separation media, and more particularly, to a process for manufacturing a lithium selective adsorbent/separation media using a recycled and augmented intercalation reaction liquor. The recycled and augmented intercalation reaction liquor is formed during intercalation and neutralization of the adsorbent manufacturing process.

A polyelectrolyte coated fly ash is described with a method of making and a method of using for the adsorption of a contaminant from a solution. The polyelectrolyte coated fly ash may be made by treating the oil fly ash with acid, and then contacting the product with a positive polyelectrolyte to create a first polyelectrolyte layer, and then with a negative polyelectrolyte to create a negative polyelectrolyte layer. The resulting polyelectrolyte coated fly ash quickly adsorbs contaminants from solution, and may be cleaned and reused.

Silver-amended carbon materials containing silver nanoparticles are prepared by a process involving an initial reduction of a porous carbon material, followed by contacting the reduced porous carbon material with an aqueous solution of a silver salt. Such silver-amended carbon materials may contain a relatively high loading of silver nanoparticles on both the outside surface and within the interior of the porous carbon material and are useful for disinfecting and/or otherwise purifying fluids such as microbe-containing fluids.

Methods of sulfurizing metal containing particles in the absence of hydrogen are described. One method includes contacting a bed of metal containing particles with a gaseous stream comprising hydrogen sulfide and inert gas under reaction conditions sufficient to produce sulfided metal containing particles. The gaseous stream is introduced into a vertical reactor at an inlet positioned at the bottom portion of the reactor and any unreacted hydrogen sulfide and inert gas is removed at an outlet positioned above the inlet. The sulfided metal containing particles can be removed from the reactor and stored.
