Desarrollo de catalizadores tándem basados en Ni/SiO2-Al2O3 y zeolita H-ZSM-5 para la oligomerización de bioetileno a biocombustible de aviación

Norman Ayllón, Eric (Universitat Politècnica de València, 2022-11-24)

[ES] A pesar de que el transporte aéreo supone únicamente el 3% de las emisiones mundiales de gases de efecto invernadero, el principal reto que afronta este sector es la dificultad para su descarbonización y, en consecuencia, ...
High-performing Ir- and Pt-containing catalysts based on mesoporous beta zeolite for the selective ring opening of decalin

Suarez, Natalia; Arribas Viana, Maria De Los Desamparados; Moreno, Andres; MARTINEZ FELIU, AGUSTIN (The Royal Society of Chemistry, 2020-02-21)

[EN] Selective ring opening (SRO) of naphthenic molecules resulting from the hydrogenation of polyaromatics is a desirable catalytic route for upgrading low-quality diesel fractions such as hydrotreated light cycle oil ...
n-Hexadecane hydrocracking Single-Event MicroKinetics on Pt/H-beta

Vandegehuchte, Bart D.; Thybaut, Joris W.; Martinez Feliu, Agustin; Arribas Viana, Maria de los Desamparados; Marin, Guy B. (Elsevier, 2012)

[EN] The Single-Event MicroKinetic (SEMK) model constructed for gas-phase hydroconversion of light n-alkanes on large-pore USY zeolites was applied, for the first time, to the hydrocracking of n-hexadecane on a Pt/H-Beta ...
Nature of Active Nickel Sites and Initiation Mechanism for Ethylene Oligomerization on Heterogeneous Ni-beta Catalysts

Moussa, Sara; Concepción Heydorn, Patricia; Arribas Viana, Maria De Los Desamparados; MARTINEZ FELIU, AGUSTIN (American Chemical Society, 2018-05)

[EN] Higher olefins produced via ethylene oligomerization are versatile commodity chemicals serving a vast range of industries with large global economic impact. Nickel aluminosilicates are promising candidates to replace ...
New bifunctional Ni H-Beta catalysts for the heterogeneous oligomerization of ethylene

Martinez Feliu, Agustin; Arribas Viana, Maria de los Desamparados; Concepción Heydorn, Patricia; Moussa-Martí, Sara (Elsevier, 2013)

[EN] The development of sustainable active and stable heterogeneous catalysts for the oligomerization of ethylene to replace the unfriendly homogenous systems based on transition metal complexes currently applied in the ...
REQUERIEMIENTOS ESTRUCTURALES Y ELECTRÓNICOS PARA EL ZrO2 EN CATALIZADORES ÁCIDOS WOx/ZrO2

Ostiz Sevilla, María del Carmen (Universitat Politècnica de València, 2011-12-19)

El presente trabajo emplea catalizadores ácidos WOx/ZrO2 modelo, soportados sobre polimorfos de ZrO2 que muestran tanto diferentes estructuras cristalinas como distintas propiedades electrónicas (ancho de banda), con el ...
The nature of active Ni sites and the role of Al species in the oligomerization of ethylene on mesoporous Ni-Al-MCM-41 catalysts

Moussa, Sara; Concepción Heydorn, Patricia; Arribas Viana, Maria De Los Desamparados; MARTINEZ FELIU, AGUSTIN (Elsevier, 2020-11-25)

[EN] Although nickel dispersed in mesoporous aluminosilicates are efficient catalysts for the oligomerization of ethylene, the nature of the active nickel sites still remains controversial. Here we applied in situ FTIR-CO ...
