Enhancement of ethylene production by alkali metal doping of MoVSb mixed oxide catalyst for ethane oxidative dehydrogenation

Ivars Barceló, F.; Solsona, B.; Asedegbega-Nieto, E.; López Nieto, José Manuel (Elsevier, 2023-06-25)

[EN] Hydrothermally prepared Mo-V-Sb mixed oxides doped with alkali metal cations (Li+, Na+, K+, Rb+, or Cs+) show a significantly improved catalytic behavior in the oxidative dehydrogenation of ethane (ODH) compared to ...
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 ...
Investigation of AFeO3 (A=Ba, Sr) Perovskites for the Oxidative Dehydrogenation of Light Alkanes under Chemical Looping Conditions

Natesakhawat, Sittichai; Popczun, Eric J.; Baltrus, John P.; Wang, Kun; Serna Merino, Pedro Manuel; Liu, Sophie; Meyer, Randall; Lekse, Jonathan W. (John Wiley & Sons, 2024-06)

[EN] Oxidative dehydrogenation (ODH) of light alkanes to produce C-2-C-3 olefins is a promising alternative to conventional steam cracking. Perovskite oxides are emerging as efficient catalysts for this process due to their ...
On the successful pelletization of a fragile mesoporous material and its mechanical stability mechanism

Morales-delaRosa, Silvia; Smales, Glen J.; Martínez-Triguero, Joaquín; Melián-Cabrera, Ignacio (Elsevier, 2025-01-01)

[EN] Mechanical stability is a crucial property for the industrial implementation of heterogeneous catalysts and adsorbents. Both particle size and shape need to be investigated for each application where, typically, a ...
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 ...
