The present invention concerns the elimination of heavy metals, in particular mercury and possibly arsenic and lead, present in a gaseous or liquid effluent by means of a capture mass comprising a support essentially based on alumina obtained by the gel method and at least one element selected from the group constituted by copper, molybdenum, tungsten, iron, nickel and cobalt. The invention is advantageously applicable to the treatment of gas of industrial origin, synthesis gas, natural gas, gas phase condensates and liquid hydrocarbon feeds.

A granulated sintered clay is provided. The granulated sintered clay with aggregate structures is porous with micropores and mesopores and has high hardness that does not collapse even in water. The granulated sintered clay has a differential pore volume with a pore diameter of 10 nm or less of 0.06 cm.sup.3/g or more in a pore distribution curve measured by a nitrogen gas adsorption method, a hardness to collapse at a planar load of 180 gf to 1200 gf in a crushing test, and a silicon dioxide content of 35 mass % to 95 mass %.

The present invention relates to a specific continuous process for preparing a zeolitic material having a framework structure type selected from the group consisting of MFI, MEL, IMF, SVY, FER, SVR, and intergrowth structures of two or more thereof, preferably an MFI- and/or MEL-type framework structure, comprising Si, Ti, and O, and to a zeolitic material as obtainable and/or obtained according to said process. Further, the present invention relates to a process for preparing a molding, and to a molding obtainable and/or obtained according to said process. Yet further, the present invention relates to a use of said zeolitic material and molding.

Adsorbents which are more hydrothermally stable, less reactive, and have longer life are described. The adsorbent comprises 60 wt % to 95 wt % zeolite, wherein the zeolite is an LTA zeolite in hydrogen, ammonium, potassium, calcium or sodium form, wherein the zeolite has a ratio of silica/alumina in a range of 1 and 1.5; 5 wt % to 30 wt % binder; 0.1 to 5 wt % phosphorous in the form of phosphoric acid, or a phosphate salt, or a pyrophosphate salt, or combinations thereof; and 0.5 to 10 wt % silica. Processes of preparing the adsorbent, and methods of drying or purifying a liquid hydrocarbon, a gas hydrocarbon, a renewable feedstocks, carbon dioxide, or combinations thereof, using the adsorbent are also described.

The present disclosure relates to a composition of super absorbent polymer and a preparation method thereof, and more specifically, a composition of super absorbent polymer and a preparation method thereof, that may improve deodorization capacity and odor masking capacity by using specific additives in combination, to effectively inhibit odor generated from urine, and the like, when applied to a product such as a diaper, and the like, and bacteria growth during wearing of a product.

The present disclosure relates to a film including a substantially crystalline water-dispersible polymer and an aromatic thermoplastic polyurethane polymer. The film has a crystallinity of at least 25%. The film expands when contacted by water. The film may include one or more apertures that can open/close in response to water. The film expands when in contact with water, but retracts as it dries, allowing for multiple insults to trigger the expansion and retraction properties of the film.

A producing method of granulated body for lithium adsorption that allows sufficiently suppressing a manganese elution in an eluting step when producing lithium on a commercial basis, includes a kneading step of kneading a powder of a lithium adsorbent precursor and a binder to obtain a kneaded product, a granulating step of granulating the kneaded product to obtain a 1st granulated body, and a sintering step of sintering the 1st granulated body to obtain a 2nd granulated body. The configuration allows a manganese valence contained in the lithium adsorbent precursor to change from 2 to 4, and thus allowing the suppressed manganese elution in the eluting step. Further, in production on a commercial basis, the lithium adsorbent can be used repeatedly. In addition, a manganese concentration in an eluent obtained in the eluting step can be suppressed, thus allowing loads in steps after the eluting step to be reduced.
