MEGIA, Pedro J.; Soria, Miguel Angel; Pereira Cerqueira, Pedro; Vizcaíno, Arturo; CARRERO, ALICIA; Calles, Jose A; Madeira, Luis Miguel, 2025, "Influence of Rh addition to transition metal-based catalysts in the oxidative steam reforming of acetic acid", https://doi.org/10.21950/ESGLOA, e-cienciaDatos, V1
In this work, the Rh-promotion to transition metal (Ni and Co) CeO2-supported catalysts has been studied for the first time on the acetic acid oxidative steam reforming. Characterization of the prepared catalysts confirmed the promoting effect of rhodium addition, allowing lower crystallite size which increases the number of available active sites... |

MEGIA, Pedro J.; Morales Cabezas, Anabel; Vizcaíno, Arturo; Calles, Jose A; CARRERO, ALICIA, 2025, "Hydrogen production through oxidative steam reforming of acetic acid over Ni catalysts supported on Ceria-based materials", https://doi.org/10.21950/DRN2GT, e-cienciaDatos, V1
Oxidative steam reforming allows higher energy efficiency and lowers coke deposition compared to traditional steam reforming. In this work, CeO2-based supports have been prepared with Ni as the active phase, and they were tested in the oxidative steam reforming of acetic acid. The in-fluence of the O2/AcOH molar ratio (0 - 0.3) has been evaluated o... |

MEGIA, Pedro J.; Morales Cabezas, Anabel; Vizcaíno, Arturo; Calles, Jose A; CARRERO, ALICIA, 2025, "Oxidative steam reforming of acetic acid on Ni catalysts: Influence of the La promotion on mesostructured supports", https://doi.org/10.21950/SGPWTE, e-cienciaDatos, V1
In this work, the support effect and the La2O3 promotion of Ni-based catalysts on the oxidative steam reforming of acetic acid as bio-oil model compound has been studied. Ni/SBA-15 showed the worst catalytic performance with an acetic acid conversion dropping below 30% at 500 ºC ascribed to active phase oxidation. In contrast, Ni supported over mes... |

MORENO DE LA CALLE, Alvaro; Vizcaíno, Arturo; CARRERO, ALICIA; Calles, Jose A; MEGIA, Pedro J., 2025, "Study of Mesostructured CeO2 Synthesis via Nanocasting Using SBA-15 as a Template: Influence of the Cerium Precursor", https://doi.org/10.21950/O8CMEE, e-cienciaDatos, V1
Mesoporous materials with high surface area, large pore volume, and adjustable pore size are promising in the fields of adsorption and heterogeneous catalysis. In this work, ordered meso-porous ceria structures were successfully prepared via nanocasting using SBA-15 as a template with Ce(NO3)3·6H2O or CeCl3·7H2O as ceria precursors. The materials w... |

MEGIA, Pedro J.; Lourdes García-Moreno; Vizcaíno, Arturo; Calles, Jose A; CARRERO, ALICIA, 2025, "Bioethanol steam reforming for hydrogen production over Ni‑Cr/SBA 15: Influence of metal loading and Ni/Cr ratio", https://doi.org/10.21950/RPTIHB, e-cienciaDatos, V1
This work examines the influence of metal loading and Ni/Cr ratio of Ni-Cr/SBA-15 catalysts on bioethanol steam reforming for the first time. The characterization of the synthesized samples reveals that higher Cr amounts results in lower Ni crystallite sizes due to the promoting effect of Cr, thereby enhancing the dispersion of the active phase. Th... |

Chirinos Chavez, Carlos Andres; MORENO DE LA CALLE, Alvaro; MEGIA, Pedro J.; Vizcaíno, Arturo; Calles, Jose A; CARRERO, ALICIA, 2025, "Exploring CeO2-doped Co/SBA-15 catalysts for acetic acid oxi-dative steam reforming", https://doi.org/10.21950/7DVG6R, e-cienciaDatos, V1
This work explores the effect of CeO2 incorporation into Co/SBA-15 catalysts on hy-drogen production through acetic acid oxidative steam reforming as a bio-oil aqueous phase model compound. CeO2 was incorporated (5–30 wt.%) to improve the physico-chemical properties of the catalyst. XRD analysis confirmed that CeO2 addition resulted in smaller Co0... |

MEGIA, Pedro J.; Rocha, Cláudio; Vizcaíno, Arturo; CARRERO, ALICIA; Calles, Jose A; Madeira, Luis Miguel; Soria, Miguel Angel, 2025, "A thermodynamic comparison between conventional, autothermal, and sorption-enhanced bio-oil steam reforming", https://doi.org/10.21950/7DRNUI, e-cienciaDatos, V1
This study presents a comprehensive thermodynamic analysis comparing three bio-oil steam reforming processes: traditional steam reforming, autothermal reforming, and sorption-enhanced steam reforming. Using Aspen Plus V12.1 software, simulations were performed to evaluate the hydrogen production, energy requirements, and the influence of key proces... |
