Activity and stability of nanosized SAPO-34 in the reaction of methanol to olefins

Li, Zhibin (Universitat Politècnica de València, 2013-06-17)

[ES] Muestras de tamaño nano de SAPO-34 sintetizado por calentamiento por microondas presenta vida mucho más alto que el estándar SAPO-34 sintetizado por el método hidrotérmico convencional en la reacción de metanol a olefinas.
Conversion of methanol to olefins: Stabilization of nanosized SAPO-34 by hydrothermal treatment

Li, Zhibin; Martínez Triguero, Luis Joaquín; Yu, Jihong; Corma Canós, Avelino (Elsevier, 2015-09)

Nano-SAPO-34 zeolite catalyst (20 nm crystal size) has been stabilized by hydrothermal treatment. After steamed at high temperatures (T >= 550 degrees C), its textural properties and high lifetime during the reaction of ...
Identification of Distinct Copper Species in Cu-CHA Samples Using NO as Probe Molecule. A Combined IR Spectroscopic and DFT Study

Concepción Heydorn, Patricia; Boronat Zaragoza, Mercedes; Millan, Reisel; Moliner Marin, Manuel; Corma Canós, Avelino (Springer-Verlag, 2017)

[EN] Combining IR spectroscopy of NO adsorption on copper exchanged molecular sieves with the chabazite structure, i.e. Cu-SAPO-34 and Cu-SSZ-13, and theoretical calculations, different types of copper species have ...
New micro and mesoporous materials for the reaction of methanol to olefins

Li, Zhibin (Universitat Politècnica de València, 2014-11-17)

(1) We will show that nano sized samples of SAPO-34 synthesized by microwave heating presents much higher lifetime than standard-SAPO-34 synthesized by conventional hydrothermal method for the reaction of methanol to ...
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 ...
