EFFECT: invention provides a high scandium recovery ratio. 16 cl, 6 dwg, 3 tbl РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 648 428 C2 (51) МПК C01F 17/00 (2006.01) C22B 59/00 (2006.01) C22B 3/42 (2006.01) B01J 45/00 (2006.01) B01J 47/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C01F 17/00 (2018.01); C22B 59/00 (2018.01); C22B 3/42 (2018.01); B01J 45/00 (2018.01); B01J 47/00 (2018.01) (21)(22) Заявка: 2015127494, 10.12.2013 10.12.2013 Дата регистрации: (73) Патентообладатель(и): Клин ТеК Пти Лтд (AU) 26.03.2018 (56) Список документов, цитированных в отчете о поиске: RU 2062810 C1, 27.06.1996.

Uzm-39 aluminosilicate zeolite

A new family of coherently grown composites of TUN and IMF zeotypes have been synthesized. These zeolites are represented by the empirical formula. Na n M m k+ T t Al 1-x E x Si y O z where "n" is the mole ratio of Na to (Al + E), M represents a metal or metals from zine, Group 1, Group 2, Group 3 and or the lanthanide series of the periodic table, "m" is the mole ratio of M to (Al + E), "k" is the average charge of the metal or metals M, T is the organic structure directing agent or agents, and E is a framework element such as gallium. These zeolites are similar to TNU-9 and IM-5 but are characterized by unique compositions and synthesis procedures and have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for carrying out various separations.

Mixed bed ion exchange resin system and method of preparation

A method for preparing non-agglomerating mixed bed ion exchange resin systems without affecting the ion exchange kinetics of the anion exchange resin component of the mixed bed system is disclosed. Pretreatment of the anion exchange resin component with a sulfonated poly(vinylaromatic) polyelectrolyte is particularly effective in providing non-agglomerated mixed bed systems without affecting ion exchange kinetics. Treatment levels of 10 to 800 milligrams per liter of anion exchange resin with sulfonated poly(vinylaromatic) polyelectrolyte having number average molecular weight from 5,000 to 1,000,000 are particularly preferred.

Metal-organic frameworks for the removal of multiple liquid phase compounds and methods for using and making same

The present invention is directed to a ligated metal-organic framework (MOF) for use in removing both anionic and cationic species from a liquid or liquid stream. The present invention also provides methods for placing the MOF on a substrate to form a MOF-containing product that can be used in the removal of certain species from a given fluid. The MOF may be a Zr-based MOF, such as NU-1000, for removal of certain anions, such as oxy-anions, or having an attached thiosulfonyl-thiol (—SO 2 —S—R 2 —SH, where R 2 is an alkyl group) ligand for complexation with certain cationic species in addition to the anions. The substrate may be any substrate to which a given MOF may be attached, including inert polypropylene polymer resin beads, a macroscopic fabric such as a mesh material or mesh filter, and a molecular fabric.

Method of making thermally regenerable salt sorbent resins

A heterogenous hybrid thermally regenerable salt sorbent resin is formed from a hybrid precursor resin. The hybrid precursor resin is formed by intimately mixing a dry, solid crosslinked macroporous copolymer with a solution containing a polyunsaturated monomer, a monoethylenically unsaturated monomer containing a haloalkyl group and a polymerization initiator, followed by heating to cause polymerization. The hybrid precursor resin is then treated with a weak base, then subjected to hydrolysis conditions to form, respectively, weak base groups and weak acid groups to produce the hybrid thermally regenerable salt sorbent resin.
