Abstract
En el presente trabajo se estudió la transformación catalítica de 5-hidroximetilfurfural (HMF) para producir
2,5-dimetilfurano (DMF) sobre catalizadores bimetálicos (PtIr) y monometálicos (Pt) soportados en materiales
mesoporosos CMK-3 y SBA-15. Se estudiaron también la temperatura y presión óptimas para lograr la máxima
producción de 2,5 DMF. Los catalizadores se caracterizaron ampliamente por XRD, isotermas de N2, XPS,
TPR, TEM y NH3-TPD. En el estudio se observó que las partículas metálicas estaban bien reducidas y muy
dispersas en la superficie del soporte debido a la gran área superficial y la distribución de poros del mismo.
Los sitios de PtIr fueron muy activos y selectivos hacia la formación del 2,5 DMF. El catalizador PtIr-CMK-
3 mostró una excelente actividad, selectividad y estabilidad para ser aplicado en este proceso.
The catalytic transformation of 5-hydroxymethylfurfural (HMF) to produce 2,5-dimethylfuran (DMF) was studied over bimetallic (PtIr) and monometallic (Pt) catalysts supported on CMK-3 and SBA-15 mesoporous materials. The optimum temperature and pressure for the maximum production of DMF were studied. The catalysts were broadly characterized by XRD, N2-isotherms, XPS, TPR, TEM and NH3-TPD. It was found that the metal particles were well reduced and highly dispersed on the surface of the support of large surface area and narrow pore distribution. The PtIr alloy species active sites were very active and selective towards the formation of the desired DMF. PtIr-CMK-3 showed an excellent activity, selectivity and stability to be applied in this process.
