Influence of lattice stability on hydrothermal deactivation of Cu-ZSM-5 and Cu-IM-5 zeolites for selective catalytic reduction of NOx by NH3

VENNESTROM, PETER NICOLAI RAVNBORG; Janssens, Ton V. W.; Kustov, Arkady; Grill, Marie; Puig-Molina, Anna; Lundegaard, Lars F.; Tiruvalam, Ramchandra R.; Concepción Heydorn, Patricia; Corma Canós, Avelino (Elsevier, 2014-01)

Copper-exchanged zeolites are well-known catalysts for the selective catalytic reduction of nitrogen oxides by ammonia (NH3-SCR). To determine the influence of framework stability on catalyst deactivation, two zeolite ...
Rational direct synthesis methodology of very active and hydrothermally stable Cu-SAPO-34 molecular sieves for the SCR of NOx

Martínez Franco, Raquel; Moliner Marin, Manuel; Franch Martí, Cristina; Kustov, Arkady; Corma Canós, Avelino (Elsevier, 2012-10-30)

A one-pot direct synthesis of Cu-SAPO-34 has been achieved that allows more than 90% yield in the material synthesis. By this method it is easy to control the Cu-loading in the Cu-SAPO-34. It is presented that a maximum ...
Selective catalytic reduction of nitrogen oxides with ammonia over microporous zeolite catalysts

VENNESTROM, PETER NICOLAI RAVNBORG (Universitat Politècnica de València, 2014-10-14)

With increasing legislative demands to remove nitrogen oxides (NOx) from automotive diesel exhaust, new catalyst systems are investigated and intensely studied in industry as well in academia. The most prevailing catalytic ...
