Abstract

Se proporciona un método para mejorar el rendimiento de un catalizador de plata para la epoxidación que comprende un portador. El portador incluye al menos 80 por ciento de alúmina alfa y tiene un volumen de poro de 0.3 mL/g a 1.2 Ml/g, un área de la superficie de 0.3 m2/g a 3.0 m2/g, y una arquitectura de poro que proporciona al menos uno de una tortuosidad de 7 o menos, una constricción de 4 o menos y una permeabilidad de 30 mdarcys o mayor. Una cantidad catalítica de plata y una cantidad de promotor de uno o más promotores está dispuesta sobre y/o en dicho portador. El método además incluye los pasos de iniciar una reacción de epoxidación al hacer reaccionar una composición del gas alimentado que contiene etileno y oxígeno presente en una relación de aproximadamente 3.5:1 a aproximadamente 12:1, en la presencia del catalizador de plata para la epoxidación a una temperatura de aproximadamente 200°C a aproximadamente 230°C; y subsecuentemente aumentar la temperatura ya sea "paso a paso" o de manera continua.
