Platinum-bismuth catalysts for treating engine exhaust

Номер: US7611680B2
Принадлежит: Nanostellar Inc

An engine exhaust catalyst containing precious metal nanoparticles is promoted with bismuth. The bismuth promotion improves the catalyst's CO oxidation performance. Also, by varying the amount of bismuth that is added, the NO conversion rate that can be realized with the catalyst can be controlled. The control over the NO conversion rate is important because the passive regenerative performance of a particulate filter used in engine exhaust systems is based on the amount NO 2 that is present in the exhaust stream that reaches the particulate filter. The amount of NO 2 being produced needs to be optimized (not necessarily maximized) so that adequate particulate filter regeneration performance can be maintained while avoiding unused, toxic NO 2 from being exhausted into the atmosphere.

Method for producing mesoporous xerogels and nanopowders in system zro2(y2o3)-al2o3 for carriers of catalysts at methane conversion into synthesis gas

Номер: RU2629667C1

FIELD: chemistry. SUBSTANCE: invention relates to the synthesis of mesoporous materials, namely, to a method for producing mesoporous xerogels and nanopowders in the system ZrO 2 (Y 2 O 3 )-Al 2 O 3 for catalyst carriers at the methane conversion into synthesis gas. The method is carried out by co-precipitating the original reagents with an aqueous ammonia solution of 0.05-0.15 M. As original reagents, 0.05-0.15 M aqueous solutions of ZrO(NO 3 ) 2 ⋅2H 2 O, Y(NO 3 ) 3 ⋅6H 2 O and Al(NO 3 ) 3 ⋅9H 2 O are used. When the hydroxides are co-precipitated in the reactor, a constant pH value is maintained in the range of 9.15 to 9.45 with a solution NH 4 Cl. After that, the co-precipitated hydroxides are dried and subjected to cryochemical treatment at a temperature of -20 to -30°C during the day. Then the obtained xerogels are heat treated at a temperature of 500-650°C to produce a metastable tetragonal solid solution based on ZrO 2 . EFFECT: production of highly disperse mesoporous xerogels and nanopowders, which are efficiently used as catalyst carriers in the development of catalytic systems. 5 dwg, 2 tbl, 3 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 629 667 C1 (51) МПК B01J 32/00 (2006.01) B82B 1/00 (2006.01) B82Y 40/00 (2011.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2016138883, 03.10.2016 (24) Дата начала отсчета срока действия патента: 03.10.2016 Дата регистрации: Приоритет(ы): (22) Дата подачи заявки: 03.10.2016 (45) Опубликовано: 31.08.2017 Бюл. № 25 5942208 А1, 24.08.1999.

Method for producing powder of conducting connection of mayenite type

Номер: RU2647290C2

FIELD: chemistry. SUBSTANCE: first a powder of the precursor of the mayenite-type compound is formed by the hydrothermal treating with a powder mixture of the raw materials of the mayenite-type compound and water. A powder of the mayenite-type compound is then formed by heating and dehydrating the precursor powder. A powder of the activated mayenite-type compound is produced by heating the dehydrated powder in an inert gas atmosphere or in a vacuum in the range of 400°C to 1000°C for at least three hours. The electrons are injected by mixing the powder of the activated mayenite-type compound with a reducing agent - Ca or CaH 2 and heating the resulting mixture from 400°C to 1100°C. The obtained powder of the conductive mayenite-type compound, which is 12CaO⋅7Al 2 O 3 , has a concentration of the conduction electrons of at least 10 15 cm -3 and a specific surface of at least 5 m 2 g -1 . After these heating steps, rapid thermal annealing can be repeated by increasing the temperature at a rate of 30 to 60°C min -1 and its maintenance at heating in a range of temperatures from 900°C to 1100°C. The metal catalyst containing medium in the form of the resulting conductive mayenite-type compounds and the applied catalyst based on transition metal, is used in the method of ammonia synthesis by the reaction of gaseous nitrogen (N 2 ) and hydrogen (H 2 ) thereon. EFFECT: invention allows to produce a mayenite-type compound having simultaneously a large specific surface area and a high conductivity. 9 cl, 2 tbl, 13 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 647 290 C2 (51) МПК C01F 7/16 (2006.01) C01F 11/02 (2006.01) B01J 23/58 (2006.01) B01J 32/00 (2006.01) C01C 1/04 (2006.01) B01J 37/02 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C01F 7/164 (2017.05); C01F 11/02 (2017.05); B01J 23/06 (2017.05); B01J 32/00 (2017.05); B01J 37/0217 (2017.05); C01C 1/0411 (2017.05) (21)(22) Заявка: 2015111257, 20.08.2013 20.08.2013 ...
