En este trabajo se sintetizaron una serie de catalizadores bimetálicos que contienen NiFe soportado en una sílica mesoporosa SBA-15 y ZrO2/SBA-15. Los catalizadores fueron evaluados en la reacción de hidrodesoxigenación (HDO) de guaiacol, un compuesto modelo del bioaceite derivado de la biomasa lignocelulósica, ampliamente seleccionado ya que contiene tres de los grupos funcionales representativos en los compuestos de este tipo de bioaceite: -OH, -OCH3, C=C aromático. Los resultados catalíticos utilizando hexadecano como solvente mostraron que la composición de los catalizadores afecta la conversión y la selectividad. Los catalizadores que contienen ZrO2, como Ni8.2Fe1.6-ZrO2/SBA-15 y Ni8.3Fe0.7-ZrO2/SBA-15, alcanzaron una elevada conversión de guaiacol del 99.0 ± 0.5 % tras 5 horas de reacción y fueron selectivos hacia ciclohexano con un bajo balance carbono. Para los catalizadores sin ZrO2 como Ni13.3Fe1.3/SBA-15 y Ni4.7Fe0.5/SBA-15 se obtiene una menor conversión de guaiacol alcanzando 85.9 ± 0.7 % luego de 5 horas de reacción y se presenta una elevada selectividad hacia ciclohexanol 80.3 ± 11.1 %. También se evidenció que la presencia de hierro conduce a un aumento en la conversión y selectividad de las especies de níquel, ya que los catalizadores monometálicos que contenían Ni mostraron una actividad catalítica menor que los catalizadores bimetálicos NiFe. La disminución de la carga de metales, Ni+Fe en Ni4.7Fe0.5/SBA-15 conduce a un aumento en la selectividad hacia ciclohexanol, alcanzando una selectividad del 77% y un balance carbono del 96.3% que indica una menor producción de subproductos o coque. Los resultados de caracterización demuestran que este material presenta la mayor concentración superficial de Ni presente como Ni0, además se tiene una densidad de sitios ácidos de fuerza media y fuerte similar. El uso de agua como solvente de reacción conduce a una conversión más baja que en hexadecano, pero con selectividad hacia productos aromáticos como catecol y fenol. Estos resultados demuestran el alto potencial de los catalizadores bimetálicos NiFe con bajas cargas de metal dispersos en soportes mesopororos como la SBA-15 en la reacción HDO. |

Palacio Olarte, Rubén AlbertoGiraldo Soto, Juan JoséQuímica de Recursos Energéticos y Medio AmbienteManrique Hernández, Alba CeciliaGonzález, Lina María2025-10-31T17:55:44Z20272025https://hdl.handle.net/10495/48061En este trabajo se sintetizaron una serie de catalizadores bimetálicos que contienen NiFe soportado en una sílica mesoporosa SBA-15 y ZrO2/SBA-15. Los catalizadores fueron evaluados en la reacción de hidrodesoxigenación (HDO) de guaiacol, un compuesto modelo del bioaceite derivado de la biomasa lignocelulósica, ampliamente seleccionado ya que contiene tres de los grupos funcionales representativos en los compuestos de este tipo de bioaceite: -OH, -OCH3, C=C aromático. Los resultados catalíticos utilizando hexadecano como solvente mostraron que la composición de los catalizadores afecta la conversión y la selectividad. Los catalizadores que contienen ZrO2, como Ni8.2Fe1.6-ZrO2/SBA-15 y Ni8.3Fe0.7-ZrO2/SBA-15, alcanzaron una elevada conversión de guaiacol del 99.0 ± 0.5 % tras 5 horas de reacción y fueron selectivos hacia ciclohexano con un bajo balance carbono. Para los catalizadores sin ZrO2 como Ni13.3Fe1.3/SBA-15 y Ni4.7Fe0.5/SBA-15 se obtiene una menor conversión de guaiacol alcanzando 85.9 ± 0.7 % luego de 5 horas de reacción y se presenta una elevada selectividad hacia ciclohexanol 80.3 ± 11.1 %. También se evidenció que la presencia de hierro conduce a un aumento en la conversión y selectividad de las especies de níquel, ya que los catalizadores monometálicos que contenían Ni mostraron una actividad catalítica menor que los catalizadores bimetálicos NiFe. La disminución de la carga de metales, Ni+Fe en Ni4.7Fe0.5/SBA-15 conduce a un aumento en la selectividad hacia ciclohexanol, alcanzando una selectividad del 77% y un balance carbono del 96.3% que indica una menor producción de subproductos o coque. Los resultados de caracterización demuestran que este material presenta la mayor concentración superficial de Ni presente como Ni0, además se tiene una densidad de sitios ácidos de fuerza media y fuerte similar. El uso de agua como solvente de reacción conduce a una conversión más baja que en hexadecano, pero con selectividad hacia productos aromáticos como catecol y fenol. Estos resultados demuestran el alto potencial de los catalizadores bimetálicos NiFe con bajas cargas de metal dispersos en soportes mesopororos como la SBA-15 en la reacción HDO.In this work, a series of bimetallic catalysts containing NiFe supported on mesoporous SBA-15 silica and ZrO2/SBA-15 were synthesized. The catalysts were evaluated in the hydrodeoxygenation (HDO) reaction of guaiacol, a model compound of bio-oil derived from lignocellulosic biomass, widely selected because it contains three of the representative functional groups found in this type of bio-oil: -OH, -OCH3, an aromatic C=C. Catalytic results using hexadecane as solvent showed that the catalyst composition affects both conversion and selectivity. Catalysts containing ZrO2, such as Ni8.2Fe1.6-ZrO2/SBA-15 and Ni8.3Fe0.7-ZrO2/SBA-15, achieved a high guaiacol conversion of 99.0 ± 0.5% after 5 hours of reaction and were selective toward cyclohexane, with a low carbon balance. For catalysts without ZrO2, such as Ni13.3Fe1.3/SBA-15 and Ni4.7Fe0.5/SBA-15, lower guaiacol conversions were obtained, reaching 85.9 ± 0.7% after 5 hours of reaction, along with high selectivity toward cyclohexanol (80.3 ± 11.1%). It was also found that the presence of iron leads to an increase in both conversion and selectivity of nickel species, as monometallic catalysts containing Ni showed lower catalytic activity than bimetallic NiFe catalysts. The reduction of the total metal loading (Ni+Fe) in Ni4.7Fe0.5/SBA-15 resulted in an increase in selectivity toward cyclohexanol, reaching 77% selectivity and a 96.3% carbon balance, indicating lower production of byproducts or coke. Characterization results demonstrated that this material exhibited the highest surface concentration of Ni present as Ni0, along with a similar density of medium and strong acid sites. The use of water as a reaction solvent led to lower conversion compared to hexadecane, but with selectivity toward aromatic products such as catechol and phenol. These results highlight the high potential of low-metal-loading NiFe bimetallic catalysts dispersed on mesoporous supports such as SBA-15 for the HDO reaction.Catálisis heterogéneaCOL0015393TRABAJO DE GRADO CON DISTINCIÓN: Mención EspecialPregradoQuímico73 páginasapplication/pdfspaUniversidad de AntioquiaQuímicaDepartamento de Ciencias BásicasMedellín, ColombiaFacultad de Ciencias Exactas y NaturalesCampus Medellín - Ciudad Universitariahttp://creativecommons.org/licenses/by-nc-sa/4.0/info:eu-repo/semantics/openAccessAttribution-NonCommercial-ShareAlike 4.0 Internationalhttp://purl.org/coar/access_right/c_abf2Catalizadores heterogéneos bifuncionales a base de metales de transición para la hidrodesoxigenación parcial de guaiacolTrabajo de grado - Pregradohttp://purl.org/coar/resource_type/c_7a1fhttp://purl.org/redcol/resource_type/TPTexthttp://purl.org/coar/version/c_b1a7d7d4d402bcceinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/draft[1] C.
