HDT process performance over noble metal-mesoporous catalysts
Vallés, Verónica Alejandra; Ledesma, Brenda Cecilia; Beltramone, Andrea Raquel (2022)The greater concentration of market demand in the diesel range forces refiners to consider redirecting internal refinery cuts to new hydrocracking units to increase the contribution to the gasoline and diesel pool. These ... -
Hydrodenitrogenation of indol using iridium catalyst supported on titanium nanotubes
Ledesma, Brenda Cecilia; Martínez, María Laura; Gómez Costa, Marcos Bruno; Beltramone, Andrea Raquel (2022)The HDN of indole was studied over iridium modified titanate nanotube catalyst.

Influence of ti incorporation to bimetallic mesoporous carbon in the production of 2,5‑dimethylfuran from biomass derivatives
Ledesma, Brenda Cecilia; Juárez, Juliana María; Domine, Marcelo E.; Beltramone, Andrea Raquel (2021)Monometallic and bimetallic supported catalysts were developed to produce 2,5-dimethylfuran (DMF) trough hydrogenolysis of 5-(hydroxymethyl)furfural (HMF). Detailed physicochemical characterization was done to understand ... -
Iridium-supported SBA-15 modified with Ga and Al as a highly active catalyst in the hydrodenitrogenation of quinoline
Ledesma, Brenda Cecilia; Martínez, María Laura; Beltramone, Andrea Raquel (2020)Ir-supported SBA-15 was studied in the hydrodenitrogenation (HDN) of quinoline as a model nitrogen com- pound. The activity was improved when Si-SBA-15 support was modified with Ga and Al. Characterization of the catalysts ... -
Magnetic Fe3O4@SiO2–Pt and Fe3O4@SiO2–Pt@SiO2 structures for HDN of indole
