Dada la necesidad de nuevos materiales catalíticos para transesterificación aceites generación biodiesel, el objetivo este trabajo fue optimizar esta reacción usando catalizadores Sr/CaO obtenidos a partir cascarón huevo mediante estudio del efecto cantidad estroncio, temperatura calcinación y método Box-Behnken. Se prepararon con 3, 6 9 %p/p Sr por 500, 650 800 °C impregnación húmeda Sr(NO3)2 disuelto en metanol. encontró que, al aumentar todas las series, también lo hace rendimiento biodiesel. Esto se debe que alta concentración generan más sitios activos superficiales. Asimismo, observó formarían especies SrCO3 cuales limitarían catalizador. Considerando los resultados, catalizador calcinado activo usado optimización. Para esto utilizó Box-Behnken tomando como factores relación molar metanol/aceite, tiempo 8 respecto aceite. óptimo 90.81% una metanol/aceite = 10, 68.58 2 h.

This study focused on generating biodiesel from waste cooking oil (WCO) employing an αFe₂O₃/CuO nanocatalyst synthesized via a co-precipitation method. Several characterization techniques, including FTIR, XRD, SEM-EDX, BET, and TEM analyses, were applied to scrutinize the features of fabricated nanocatalyst. The results confirmed successful incorporation CuO into αFe₂O₃ structure. BET analysis further revealed that addition nanoparticles significantly enhanced catalyst's surface properties, increasing number active sites available for transesterification reactions. Besides, exhibited specific area 334 m²/g, highlighting its high availability catalytic activity. process was statistically optimized using response methodology (RSM) with Box-Behnken design (BBD) assess influence critical reaction parameters. Vital parameters evaluated included temperature (50–70 °C), methanol/WCO molar ratio (8–14 mol/mol), catalyst loading (1–3 wt%). Moreover, ANOVA indicated proportion had most remarkable effect production efficiency, F-value 337.11. Under optimal conditions time 3 h, 11, dosage 2 wt%, 60 °C highest yield 94.27% achieved. Additionally, reusability assessment demonstrated notable stability, only 12% reduction in efficiency observed over seven cycles. research demonstrates nanocatalysts, owing their unique have potential serve as highly effective heterogeneous catalysts transesterification.
