Preguntas orientadoras para la síntesis de catalizadores y su uso en reacciones de oxidación catalítica selectiva

Resumen

En el presente documento se presenta una breve historia de la catálisis, así como de los procesos de oxidación selectiva de hidrocarburos. Por otra parte, se mencionan los conceptos básicos involucrados en la catálisis heterogénea haciendo énfasis en el papel de los materiales catalíticos en procesos químicos de oxidación y planteando una serie de preguntas orientadoras que se deben seguir al momento de abordar un proceso catalizado por materiales sólidos. De la misma manera, se muestra los métodos de síntesis de catalizadores denominados en la literatura como sol-gel e impregnación, identificando la influencia de cada etapa de preparación con las propiedades físicas y químicas de los materiales. Finalmente, se presenta un caso de estudio aplicado a la oxidación catalítica selectiva de metano y metanol empleando materiales catalíticos de hierro, molibdeno y vanadio sintetizados por el método sol-gel.

Palabras clave: catálisis heterogénea, preguntas orientadoras, oxidación selectiva, metano, metanol, formaldehido, sol-gel, impregnación, síntesis de catalizadores, calcinación
