Adsorbent filter media particularly suited for removal of biological contaminants in process liquids. A porous fixed bed of adsorbent material is formed, using only a granular adsorbent and a water-insoluble thermoplastic binder. The resulting composite filter allows for a higher amount of adsorbent with smaller adsorbent particles than conventional depth filters. Elimination of cellulose fiber, as well as the elimination of the thermoset binder, results in reduced contamination of the process liquid.

Принадлежит: ExxonMobil Research and Engineering Co

A gas separation process uses a structured particulate bed of adsorbent coated shapes/particles laid down in the bed in an ordered manner to simulate a monolith by providing longitudinally extensive gas passages by which the gas mixture to be separated can access the adsorbent material along the length of the particles. The particles can be laid down either directly in the bed or in locally structured packages/bundles which themselves are similarly oriented such that the bed particles behave similarly to a monolith but without at least some disadvantages. The adsorbent particles can be formed with a solid, non-porous core with the adsorbent formed as a thin, adherent coating on the exposed exterior surface. Particles may be formed as cylinders/hollow shapes to provide ready access to the adsorbent. The separation may be operated as a kinetic or equilibrium controlled process.

HYBRID ANION EXCHANGER IMPREGNATED WITH HYDRATED ZIRCONIUM OXIDE FOR SELECTIVE REMOVAL OF CONTAMINATING LIGAND AND METHODS OF MANUFACTURE AND USE THEREOF

Polymeric anion exchanger are used as host materials in which sub-micron sized hydrated Zr(IV) oxides (HZrO) particles are irreversibly dispersed within the ion exchange medium, such as beads or fibers. The HZrO can be impregnated into the pore structure of resin by mixing the parent anion exchange resin with zirconium solution prepared by pre-calcined zirconium oxide dissolved in concentrated mixture of alcohol and acid, and then followed by precipitation of HZrO particles within the resin by using alkaline solution. Since the anion exchangers have positively charged such as quaternary ammonium functional groups, anionic ligands such as arsenate, fluoride can transport in and out of the gel phase without subjected to the Donnan exclusion effect. Consequently, anion exchanger-supported HZrO submicron particles exhibit significantly greater capacity to remove arsenic and fluoride in comparison with parent anon exchange resins. Known cation exchange resins as support materials do not offer high arsenic or fluoride removal capacity. 1. A method of preparing a hybrid anion exchange resin , the method comprising the steps of:preparing a zirconium solution by dissolving zirconium oxide into a solution comprising an organic solvent and an acid;bringing a polymeric anion exchange resin in contact with the zirconium solution to form a resin-zirconium material;drying the resin-zirconium material;subsequently contacting the dried resin-zirconium material with an aqueous alkaline solution to precipitate a zirconium compound within a gel phase of the anion exchange resin; andafter the step of contacting, washing the anion exchange resin an aqueous wash liquid, followed by optionally rinsing with a non-aqueous rinse liquid, and then drying to yield a dried zirconium-impregnated anion exchange resin impregnated with at least one of a an oxygen-containing compound of zirconium, wherein the zirconium-impregnated anion exchange resin is suitable for use in removing at least one ...

Utilization of lignin-rich biomass

Номер: US20130312472A1
Автор: Benjamin Brehmer, Jens Busse
Принадлежит: EVONIK DEGUSSA GmbH

The invention relates to a method for utilizing biomass, in which the biomass is pyrolyzed during a heat treatment process to obtain driven-out gas and remaining carbon-rich solids. It is an object of the invention to specify a method for utilizing biomass, which is based on comparatively expensive feedstocks, but in return gives products of value with unusually good properties, the proceeds of which make the process economically viable. This object is achieved firstly by using a biomass having a lignin content of 10 to 30% by weight and a water content of 5 to 25% by weight, and by virtue of a heat treatment process comprising three residence times each on a respective level of temperature, wherein the first residence time lasts between 10 and 40 minutes, particularly of 30 minutes at a temperature level between 130 and 280° C., particularly of 250° C.; the second residence time lasts between 5 and 30 minutes, particularly of 10 minutes at a temperature level between 300 and 500° C., particularly of 400° C.; the third residence time lasts between 10 and 60 minutes, particularly of 20 minutes at a temperature level between 650 and 900° C., preferred between 700 and 900° C., particularly of 750° C.

A method for producing biochar particles or pellets which use sulphur and other additives. The method includes producing a mixture with biochar and additives selected from sulphur, lignin, and gluten. The mixture is mixed with water and passed through an extruder to produce an extrudate. The extrudate is then cut into pellets. The pellets are then tumbled/spun with each other and heated to result in mostly spheroidal pellets whose mechanical characteristics allow them to be used with well-known agricultural equipment. The biochar can be produced with sulphur incorporated as an outer coating. To produce this sulphur coated biochar, the method includes feeding a biomass feedstock to a pyrolysis reactor, pyrolyzing the feedstock into biochar particles, size-sorting the biochar particles, and coating the biochar particles with the sulphur coating material. 1. A method for producing biochar pellets , the method comprising:a) mixing biochar with at least one additive and water to result in a mixture;b) extruding said mixture to result in an extrudate;c) cutting said extrudate into pellets;d) heating said pellets for a predetermined time at a predetermined temperature and then cooling said pellets; ande) processing said pellets in a spheronization device which heats said pellets and forces said pellets to tumble against one another while being heated.2.

A novel microporous carbon molecular sieve may be used as the basis for carbon adsorbent pellets that have discrete areas of carbonized binder and of carbonized precursor, macropores having an average pore diameter greater than or equal to 1 micrometer and a total macroporosity of at least 30 percent, both as measured by mercury porosimetry, and micropores that are capable of selectively admitting a C2-C3 alkene and excluding a C2-C3 alkane, and a total microporosity ranging from 10 percent to 30 percent. The pellets may be prepared by pyrolyzing a pellet structure comprising a carbon forming, non-melting binder and a non-porous gel type sulfonated polystyrene precursor at a temperature ranging from 500° C. to 1000° C., under an inert atmosphere and other conditions suitable to form the described pellets. The pellets are particularly useful in pressure swing and temperature swing adsorption processes to separate C2-C3 alkane/alkene mixtures. 1.
