[EN] In the presented manuscript an influence of the mesoporosity generation in commercial ZSM-5 zeolite on its catalytic performance in two environmental processes, such as NO reduction with ammonia (NH3SCR, Selective ...
Ferrierite and Its Delaminated Forms Modified with Copper as Effective Catalysts for NH3-SCO Process

Swies, Aneta; Rutkowska, Malgorzata; Kowalczyk, Andrzej; DÍAZ MORALES, URBANO MANUEL; Palomares Gimeno, Antonio Eduardo; Chmielarz, Lucjan (MDPI AG, 2020-11)

[EN] Ferrierites and their delaminated forms (ITQ-6), containing aluminum or titanium in the zeolite framework, were synthetized and modified with copper by an ion-exchange method. The obtained samples were characterized ...
Mesoporous Beta zeolite functionalisation with FexCry oligocations; catalytic activity in the NH3-SCO process

Rutkowska, M.; Duda, M.; Macina, D.; Górecka, S.; Debek, R.; Moreno-Rodríguez, José María; DÍAZ MORALES, URBANO MANUEL; Chmielarz, L. (Elsevier, 2019-04)

[EN] In the presented study, H-Beta zeolite and H-Beta/meso (mesoporous Beta zeolite obtained by a mesotemplate-free method) were modified with Fe-3, Fe2Cr, FeCr2 and Cr-3 triple-metallic aggregates (oligocations) by ...
Preparación y caracterización de catalizadores basados en Ag-zeolitas para la reacción de oxidación catalítica de amoniaco

López Hernández, Irene (Universitat Politècnica de València, 2017-08-31)

Las emisiones de amoniaco constituyen un grave problema de contaminación atmosférica relacionado con ciertos procesos como la producción de amoniaco, las plantas de gasificación de biomasa y las emisiones residuales de los ...
Selective ammonia oxidation over ZSM-5 zeolite: Impact of catalyst's support porosity and type of deposited iron species

Borcuch, A.; Rutkowska, M.; Marzec, A.; Kowalczyk, A.; Michalik, M.; Moreno, J.M.; DÍAZ MORALES, URBANO MANUEL; Chmielarz, L. (Elsevier, 2020-05-15)

[EN] In the presented studies an influence of different parameters, such as zeolite sample porosity, form of used iron source ([Fe-3(OAc)(6)O(H2O)(3)](+)oligocations or FeSO4 solutions) and method of iron species deposition ...
