Catalizadores heterogéneos para la síntesis de piperazinas a partir de glicerol

Mazarío Santa-Pau, Jaime (Universitat Politècnica de València, 2020-09-02)

[ES] El objetivo principal del trabajo es el estudio de un proceso para la síntesis de productos nitrogenados de alto valor añadido a partir de glicerol empleando catalizadores heterogéneos sostenibles. En concreto, el ...
Catalytic transformations of glycerol via hydroxyacetone into nitrogen heterocycles of industrial interest

Mazarío Santa-Pau, Jaime (Universitat Politècnica de València, 2022-01-17)

[ES] La presente tesis doctoral aborda el desarrollo de nuevos procesos catalíticos centrados en la valorización del glicerol, subproducto principal en la síntesis de biodiesel. El objetivo principal del trabajo consiste ...
Continuous catalytic process for the selective dehydration of glycerol over Cu-based mixed oxide

Mazarío-Santa-Pau, Jaime; Concepción Heydorn, Patricia; Ventura, María; Domine, Marcelo Eduardo (Elsevier, 2020-05)

[EN] The selective dehydration of glycerol to hydroxyacetone (acetol) was studied with Cu-based mixed oxides derived from hydrotalcite as catalysts in a continuous flow fix-bed reactor. Catalysts were prepared by ...
Hidrogenación selectiva de ésteres grasos y triglicéridos con catalizadores basados en Ni soportado sobre óxidos mixtos.

Pino, Byron (Universitat Politècnica de València, 2021-11-14)

[ES] La demanda de energía en el mundo presenta un continuo incremento, siendo la dependencia de combustibles fósiles (gas, petróleo, carbón) para producir esta energía cada vez más acentuada. El uso de combustibles fósiles ...
Hydrotalcite-Modified Clinoptilolite as the Catalyst for Selective Catalytic Reduction of NO with Ammonia (NH3-SCR)

Szymaszek-Wawryca, Agnieszka; Summa, Paulina; Duraczynska, Dorota; DÍAZ MORALES, URBANO MANUEL; Motak, Monika (MDPI AG, 2022-11)

[EN] A series of clinoptilolite-supported catalysts, modified with hydrotalcite-like phase (HT) by co-precipitation, were prepared and tested in NH3-SCR reactions. It was found that deposition of HT on clinoptilolite ...
NOx selective catalytic reduction at high temperatures with mixed oxides derived from layered double hydroxides

Palomares Gimeno, Antonio Eduardo; Franch Martí, Cristina; Ribera, Antonio; Abellán, G. (Elsevier, 2012-09-15)

[EN] Mixed oxides derived from layered double hydroxides (LDHs) have been investigated as potential catalysts for the NOx removal at high temperatures. The best results were obtained with Co–Al mixed oxides derived from ...
Unlocking mixed oxides with unprecedented stoichiometries from heterometallic metal-organic frameworks for the catalytic hydrogenation of CO2

Castells-Gil, Javier; Ould-Chikh, Samy; Ramírez, Adrian; Ahmad, Rafia; Prieto González, Gonzalo; Rodríguez Gómez, Alberto; Garzón-Tovar, Luis; Telalovic, Selvedin; Liu, Lingmei; Genovese, Alessandro; Padial, Natalia M.; Aguilar-Tapia, Antonio; Bordet, Pierre; Cavallo, Luigi; Martí-Gastaldo, Carlos (Cell Press, 2021-07-15)

[EN] Their complex surface chemistry and high oxygen lattice mobilities place mixed-metal oxides among the most important families of materials. Modulation of stoichiometry in mixed-metal oxides has been shown to be a very ...
