Provided here are adsorbent compositions containing polyvinyl alcohol-bonded pellets of zeolite templated carbon. Also provided here are methods of producing adsorbent compositions by forming an aqueous mixture containing a binder, water, and zeolite-templated carbon; subjecting the aqueous mixture to a drying process to remove the water and form a dry mixture of the binder and the zeolite-templated carbon, and compacting the dry mixture of the binder and the zeolite-templated carbon to form the binder-bonded pellets of the zeolite templated carbon.

A tablet having a deliquescent desiccant and a fragrance encapsulated on or within a binding agent. The tablet is in a pressed form. A method of making a tablet involves providing a deliquescent desiccant, encapsulating a fragrance by spray drying the fragrance on a carbohydrate, combining the deliquescent desiccant and the carbohydrate encapsulated fragrance, and pressing the combination into the tablet.

The present disclosure provides for a porous gas sorbent monolith with superior gravimetric working capacity and volumetric capacity, a gas storage system including a porous gas sorbent monolith of the present disclosure, methods of making the same, and method for storing a gas.

The powder adsorbent materials (1a, 1b) include free adsorbent materials (1a) free-movably contained in the voids (3) between the resin structures (2), and fixed adsorbent materials (1b) fixed to a surface (2a) of the resin structure (2) and/or at least partly embedded inside the resin structure (2), and the powder adsorbent materials (1a, 1b) are at least one of powdered activated carbon, powdered activated clay, and zeolite.

A fertilizer/soil conditioner or a fuel source material is formed by processing animal waste by-products through the use of a rotary biomass dryer system. The animal waste by-product includes without limitation manure obtained from cattle or swine; feed lot bedding, poultry litter, a digestate of animal waste by-products obtained from an anaerobic digester, municipal waste, waste meat renderings, waste meat, or a mixture thereof. The processed material may comprise a higher amount of ash and a lower amount of volatile material than the animal waste by-product. The processed material may be stored as a powder or processed into pellets, logs, pucks, briquettes or another convenient shape form.

Embodiments provided herein are compositions directed to porous iron oxides, which are suitable for removing hydrogen sulfide and other sulfur-containing organic contaminants from hydrocarbon streams, and in which the iron oxide component of the composition contains both maghemite and hematite phases, with maghemite forming the greater portion of these phases. In some embodiments, magnetite, aluminum oxide, alumina silicate, and a binder comprised of an organic substance are homogenized, followed by calcining which burns away the organic and converts magnetite to a mix of maghemite and hematite.

A water purification apparatus and a water purification method capable of effectively using a layered double hydroxide and easily being applied are described. A water purification apparatus for removing a polluted substance from polluted water includes a solid-liquid separator that separates the polluted water and a solid material from each other, and a polluted substance remover that removes, by a layered double hydroxide, the polluted substance contained in the polluted water separated by the solid-liquid separator.

A method for producing an iron-containing filter material for water treatment includes the steps of reacting a trivalent iron compound and a base inside a vessel until the trivalent iron is completely neutralized, to obtain an iron hydroxide and a salt consisting of the anion of the trivalent iron compound and the cation of the base; feeding the iron hydroxide and the salt into ceramic membranes to wash the iron hydroxide from the salt in cross-flow; feeding the iron hydroxide suspension to a membrane filter press where part of the water is removed, to obtain a panel having a moisture content of less than 77% by weight; inserting the panel into containers; and positioning the containers inside a refrigeration chamber operating at atmospheric pressure and at temperatures less than 0° C. for a time between 24 and 240 hours.

[Object] To provide a method for producing a water-absorbent resin in powder form or particle form, which has excellent physical properties such as water absorption performance and the like, at high productivity. [Solution] A method for producing a water-absorbent resin includes: a polymerization step of polymerizing a monomer, which is a raw material of the water-absorbent resin, to obtain a hydrous gel crosslinked polymer dispersed in an organic solvent; and a separation step of separating the organic solvent and the hydrous gel crosslinked polymer. The separation step includes transfer, compression, and discharge of the hydrous gel crosslinked polymer.

A filter for a water-purification device includes a filter housing having a water inlet and a water outlet defined therein, and a filter member disposed in the filter housing to purify water introduced through the inlet and supply the purified water to the outlet. The filter member includes a carbon block produced by mixing 40 to 50% by weight of titanium oxide, 30 to 40% by weight of activated carbon, and 18 to 23% by weight of binder with each other.
