Abstract

processo para iniciar um catalisador de óxido de etileno altamente seletivo é provido de partida para epoxidação de etileno. o processo inclui iniciar uma reação de epoxidação reagindo uma composição de gás de alimentação na presença de um catalisador de epoxidação a um primeira temperatura de cerca de 108 °c a cerca de 210 °c. a primeira temperatura é aumentada para uma segunda temperatura de cerca de 230 °c a cerca de 290 °c, por um período de tempo de cerca de 6 horas a cerca de 50 horas, simultaneamente adicionando uma concentração suficiente de moderador de forma que a quantidade de moderador absorvida no catalisador depois de atingir a segunda temperatura seja cerca de 10 a cerca de 50 g/m ^3^ de catalisador. a segunda temperatura é mantida por cerca de 50 horas a cerca de 350 horas, regulando ao mesmo tempo a composição de gás de alimentação para conter cerca de 0,5 % a cerca de 25 % de co ~2~. a segunda temperatura é diminuída para uma terceira temperatura, simultaneamente aumentando a concentração do moderador para um nível maior que a concentração suficiente.
