Abstract

Un método para la fabricacion de un catalizador con resistencia al desgaste mejorada que tiene una capa superficial rica en oxido que involucra formar unasuperficial rica en oxido que involucra formar una suspension que comprende; partículas de catalizador, precursor del catalizador o soporte del catalizador(p.ej. oxidos de metales de transicion), un sol de oxido coloidal,(p.ej. sílice coloidal), y una solucion de un solvente y un soluto en el cual el solutoconsiste esencialmente de un precursor de dicha superficie rica en oxido con tamano de partícula no mayor de 5nm (p.ej. ácido silícico o ácido polisilícicoacuoso) y luego secar por atomizado la suspension para formar microesferas de catalizador resistente al desgaste; y calcinar las microesferas secadas poratomizado. Tal catalizador es particularmente util en procesos de oxidacion donde la oxidacion se realiza por medio de una forma oxidada de catalizador y laforma reducida del catalizador resultante es regenerada por separado (p.ej. procesos en fase vapor de dos etapas llevados a cabo en reactores con recirculacionde solidos, reactores de lecho transportado o reactores de lecho fluidizado circulante y similares).
