A series of Ni catalysts supported on Al2O3 and Fe as promoter were prepared through co-precipitation technique by changing the Fe/Al ratio (0, 25 and 75% molar). The prepared samples were characterized by several techniques (XRD, H2-TPR, N2 adsorption and ICP-OES). All the catalysts showed a low carbon conversion to gas and high carbon conversion to liquid products mainly 1, 2-propanediol, acetol and ethylene glycol. This work demonstrates the effects of the molar ratio of Fe/Al on physicochemical characteristics of Ni-Al-Fe catalysts and during the pressure aqueous processing (PAP) of glycerol to value-added products.

El presente trabajo estudió el procesamiento acuoso a presión de glicerol (subproducto del biodiesel) sin adición externa de hidrógeno para producir productos de valor agregado. Se prepararon una serie de catalizadores de Ni soportados sobre Al2O3 y Fe como promotor mediante la técnica de coprecipitación cambiando la relación Fe/Al (0, 25 y 75% molar). Las muestras preparadas se caracterizaron mediante varias técnicas (DRX, H2-TPR, adsorción de N2 e ICP-OES). Todos los catalizadores mostraron una baja conversión de carbono a gas y una alta conversión de carbono a productos líquidos, principalmente 1,2-propanodiol, acetol y etilenglicol. Este trabajo demuestra los efectos de la relación molar de Fe/Al sobre las características fisicoquímicas de los catalizadores de Ni-Al-Fe y durante el procesamiento acuoso a presión (PAP) de glicerol para obtener productos de valor agregado.</dc:description><dc:date>2019</dc:date><dc:source>http://zaguan.unizar.es/record/99405</dc:source><dc:doi>10.5071/27thEUBCE2019-3DV.4.15</dc:doi><dc:identifier>http://zaguan.unizar.es/record/99405</dc:identifier><dc:identifier>oai:zaguan.unizar.es:99405</dc:identifier><dc:relation>info:eu-repo/grantAgreement/ES/AEI-FEDER/CTQ2017-86893-R</dc:relation><dc:relation>info:eu-repo/grantAgreement/ES/DGA-FEDER/T22-17R</dc:relation><dc:identifier.citation>European biomass conference and exhibition proceedings 27, 3DV.4.15 (2019), 1432-1435</dc:identifier.citation><dc:rights>by-nc-nd</dc:rights><dc:rights>http://creativecommons.org/licenses/by-nc-nd/3.0/es/</dc:rights><dc:rights>info:eu-repo/semantics/openAccess</dc:rights></dc:dc>
