Resumen

La recuperación térmica mejorada de crudos pesados requiere nanomateriales multifuncionales capaces de estabilizar interfases y catalizar oxidaciones en condiciones de yacimiento. Las nanopartículas de Fe2O3 (Fe2O3-NPs) son candidatas prometedoras por su actividad redox y potencial como estabilizadores de emulsiones Pickering, aunque su desempeño dual depende del control de la química superficial. El objetivo fue diseñar y caracterizar Fe2O3-NPs de doble función, activas como estabilizadores de emulsiones Pickering y catalizadores tipo Fenton, mediante funcionalización superficial con agentes de acoplamiento de silano (SiCAs). Las Fe2O3-NPs se funcionalizaron con propiltrimetoxisilano (C3), octiltrietoxisilano (C8) y hexadeciltrimetoxisilano (C16) mediante hidrólisis de grupos alcoxi y condensación con grupos –OH superficiales, caracterizando área BET, tamaño de partícula (DLS), ángulo de contacto y química superficial (XPS, FTIR-ATR); las nanopartículas se emplearon en nanofluidos polares y no polares, evaluando su actividad interfacial en emulsiones Pickering agua/hidrocarburo a distintas concentraciones. La funcionalización moduló la actividad interfacial, con ángulos de contacto entre 20° y 167°, sin pérdida de área activa ni formación de multicapas; la estabilidad y el tipo de emulsión (O/W o W/O) se correlacionaron con el balance hidrófilo-hidrófobo de las partículas. Los sitios activos de Fe2O3 se conservaron tras la funcionalización, permitiendo desempeño dual como estabilizador interfacial y catalizador de oxidación heterogénea, con potencial aplicación en combustión in-situ para recobro térmico. Este trabajo fue financiado por Colciencias-ANH, proyecto "Preparación de nanomateriales basados en metales de transición para procesos ligados al recobro térmico de crudos colombianos y análisis de su comportamiento catalítico en procesos de combustión in-situ"
