  • Quantification of the sulfidation extent of Mo in CoMo HDS catalyst through XPS 
    ROMERO GALARZA, ADOLFO; Bravo-Sanchez, Mariela; Ramírez Solis, Jorge Fernando; GUTIERREZ ALEJANDRE, AIDA; Solís Casados, Dora Alicia (Elsevier, 2019-07-01)
    Background removal in X-ray photoelectron spectroscopy (XPS) spectra was carried out in Co–Mo hydrodesulfurization (HDS) catalysts supported alumina using traditional and recent methods. The sulfidation extent, expressed ...
  • Relevant changes in the properties of Co(Ni)Mo/Al2O3 HDS catalysts modified by small amounts of SiO2 
    ROMERO GALARZA, ADOLFO; GUTIERREZ ALEJANDRE, AIDA; Ramírez Solis, Jorge Fernando; Solís Casados, Dora Alicia (Journal of Materials Research, 2018-08-13)
    The changes in hydrodesulfurization activity, selectivity, dispersion, sulfidation, and extent of promotion of Co(Ni)Mo catalysts were investigated when the alumina support surface is modified by grafting 4 wt% silica. ...
