Abstract

Se proporciona un proceso de arranque para la epoxidación de etileno. El proceso incluye la iniciación de una reacción de epoxidación para hacer reaccionar una composición deI gas de alimentación en la presencia de un catalizador de epoxidación en una primera temperatura de aproximadamente 180°C hasta aproximadamente 210°C. La primera temperatura es aumentada a una segunda temperatura de aproximadamente 230°C hasta aproximadamente 290°C, por un período de tiempo de aproximadamente seis horas hasta aproximadamente 50 horas, mientras se agrega simultáneamente una concentración suficiente del moderador de modo que la cantidad del moderador adsorbida en el catalizador después de lograr la segunda temperatura es de aproximadamente 10 g/m3 hasta aproximadamente 50 g/m3 de catalizador. La segunda temperatura es mantenida por un período de aproximadamente 50 horas hasta aproximadamente 350 horas, mientras se regula la composición del gas de alimentación para contener de aproximadamente el 0.5% hasta aproximadamente el 25% de CO2. La segunda temperatura es disminuida a una tercera temperatura, mientras se aumenta simultáneamente la concentración del moderador a un nivel mayor que la concentración suficiente.
