Catalytic valorization of natural gas and biomass-derived feedstocks by metal oxides

Delgado Muñoz, Daniel (Universitat Politècnica de València, 2019-06-11)

[ES] La presente tesis doctoral se sitúa en el marco de la actual transición energética, que plantea la sustitución progresiva de materias primas de origen fósil por fuentes renovables, tanto para la obtención de productos ...
Chemical, Structural, and Morphological Changes of a MoVTeNb Catalyst during Oxidative Dehydrogenation of Ethane

Valente, Jaime S.; Armendariz-Herrera, Héctor; Quintana-Solorzano, Roberto; Del Angel, Paz; Nava, Noel; Massó Ramírez, Amada; López Nieto, José Manuel (American Chemical Society, 2014)

MoVTeNb mixed oxide, a highly active and selective catalyst for the oxidative dehydrogenation of ethane to produce ethylene, exhibits the so-called M1 and M2 crystalline phases. The thermal stability of the MoVTeNb ...
Control of zeolite framework flexibility and pore topology for separation of ethane and ethylene

Bereciartua-Pérez, Pablo Javier; Cantin Sanz, Angel; Corma Canós, Avelino; Jorda Moret, Jose Luis; Palomino Roca, Miguel; Rey Garcia, Fernando; Valencia Valencia, Susana; Corcoran Jr., Edward W.; Kortunov, Pavel; Ravikovitch, Peter I.; Burton, Allen; Yoon, Chris; Wang, Yu; Paur, Charanjit; Guzman, Javier; Bishop, Adeana R.; Casty, Gary L. (American Association for the Advancement of Science (AAAS), 2017-11-24)

[EN] The discovery of new materials for separating ethylene from ethane by adsorption, instead of using cryogenic distillation, is a key milestone for molecular separations because of the multiple and widely extended uses ...
Design of an ultra low temperature freezer for vaccine or other medical use using natural refrigerants

Bovaira Dalmau, José (Universitat Politècnica de València, 2022-09-22)

[ES] Resumen del trabajo: El objetivo del trabajo es diseñar un ultracongelador capaz de almacenar unos (150-200) litros de vacunas Pzizer a una temperatura en el rango de los (-85,-80) grados celcius utilizando un ciclo ...
Influence of the Nature of the Promoter in NiO Catalysts on the Selectivity to Olefin During the Oxidative Dehydrogenation of Propane and Ethane

Delgado Muñoz, Daniel; Sanchis, Rut; Solsona Espriu, Benjamin Eduardo; Concepción Heydorn, Patricia; López Nieto, José Manuel (Springer-Verlag, 2020-12)

[EN] A comparative study of the catalytic properties for the oxidation of C2-C3 alkanes and olefins has been carried out over unpromoted and M-promoted NiO catalysts (Me¿=¿K, La, Ce, al, Zr, Sn, Nb). The catalysts have ...
Optimizing Reflux Synthesis Method of Mo-V-Te-Nb mixed oxide Catalysts for Light Alkane Selective Oxidation

Massó Ramírez, Amada; Ivars-Barceló, Francisco; López Nieto, José Manuel (Elsevier, 2020-10-01)

[EN] The investigation here presented studies the effect of the synthesis temperature (from 80 to 110 degrees C) and the time (from 1 to 4 days) employed to precipitate catalyst precursors by reflux method, on the ...
Oxidative dehydrogenation of ethane: A study over the structure and robustness of Ni-W-O catalysts

Agouram, S.; Dejoz, A.; Ivars Barceló, Francisco; Vazquez, I.; López Nieto, José Manuel; Solsona, B. (Elsevier, 2014-03)

[EN] The robustness of one selected Ni-W-O catalyst has been studied in the oxidative dehydrogenation of ethane. This catalyst initially deactivates for the first 10 h online decreasing 15% of its catalytic activity compared ...
Promoted NiO catalysts for the oxidative dehydrogenation of ethane

López Nieto, José Manuel; Solsona Espriu, Benjamin Eduardo; Grasselli, Robert K.; Concepción Heydorn, Patricia (Springer Verlag (Germany), 2014-09)

Metal oxide promoted NiO catalysts with a Ni/(Me + Ni) atomic ratio 0.92 have been investigated for the oxidative dehydrogenation of ethane. These materials have been characterized by several techniques (N-2-adsorption, ...
Selective oxidation of ethane: Developing an orthorrombic phase in Mo-V-X (X=Nb,Sb,Te) mixed oxides

Botella Asuncion, Pablo; Dejoz, A.; Abello, M. C.; Vazquez, M. I.; Arrua, L.; López Nieto, José Manuel (Elsevier, 2009-04-30)

[EN] Mo-V-X (X = Nb, Sb and/or Te) mixed oxides have been prepared by hydrothermal synthesis and heat-treated in N(2) at 450 degrees C or 600 degrees C for 2 h. The calcination temperature and the presence or absence of ...
