Abstract

método para melhorar o desempenho de um catalisador de epoxidação à base de prata, compreendendo um veículo consistindo em pelo menos 80 por cento de alfa alumina e tendo um volume de poro de 0,3 ml/g a 1,2 ml/g, uma área superficial de 0,3 m²/g a 3,0 m²/g, e uma arquitetura de poros que fornece pelo menos uma tortuosidade de 7 ou menos, uma constrição de 4 ou menos e uma permeabilidade de 30 mdarcy ou maior. uma quantidade catalítica de prata e uma quantidade promotora de um ou mais promotores dispostos no referido veículo. o método inclui adicionalmente as etapa de início de uma reação de epoxidação por reação de uma composição de gás de alimentação contendo etileno e oxigênio presentes em uma proporção de cerca de 3,5: 1 a cerca de 12: 1, na presença do catalisador de epoxidação à base de prata a uma temperatura de cerca de 200°c a cerca de 230°c; e subsequentemente aumentando a temperatura, de forma gradual ou contínua.
