Abstract

Se proporcionan recubrimientos de catalizador con porosidad mejorada y métodos para confeccionar los recubrimientos. El proceso comprende la incorporación de una macroemulsión de aceite en agua en la suspensión de catalizador previo al recubrimiento del sustrato portador, y calcinar el sustrato portador recubierto para quitar la macroemulsión de aceite en agua. También se proporcionan artículos de catalizador que comprenden el recubrimiento y métodos para la eliminación de emisiones de gases de escape.
