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... |
Jul 17, 2025 - Green hydrogen production from waste biomass pyrolysis fractions by auto-thermal reforming in a membrane reactor BIOWASTETOH2
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... |

The project (BiowastetoH2) aims to contribute to the decarbonisation of the European energy system by producing green hydrogen from waste streams. This, the main objective of the project is the production of renewable hydrogen from residual streams from biomass pyrolysis by means of autothermal steam reforming integrated in a membrane reactor. Focu... |

In this project, a novel, sustainable and pH-sensitive nanocomposite was designed for the targeted delivery of 5-fluorouracil (5-FU) against breast cancer cells. The nanodelivery system is based on graphitic carbon nitride (g-C3N4) coated with Gelatin (G)/Polyethylene glycol (PEG) biopolymers, and was prepared by W/O/W double emulsion technique usi... |

Climate change poses a significant threat to Afrotemperate flora, particularly to the species isolated in high-altitude ecosystems, such as in the East African sky islands. This study assesses the vulnerability of Afrotemperate flora, using tropical Afroalpine and Afromontane Helichrysum (Compositae) taxa as a model system, by evaluating their clim... |

The production of novel industrially demanded materials mediated by metal-based catalysts under greener and more eco-friendly conditions is a current challenge to aim. This is even more attractive when these materials are capable to uptake different levels of CO2 and show improved properties. In this contribution we describe the use of inexpensive,... |
