Abstract
resumo carreador modificado para catalisador de óxido de etileno baseado em prata catalisadores de óxido de etileno baseado em prata tendo estabilidade aumentada são revelados. os catalisadores de óxido de etileno baseados em prata de estabilidade aumentada incluem um carreador alumina que tem sido modificado para incluir cavidades na superfície do carreador. a presença das cavidades na superfície do carreador modificado para ou pelo menos impede a movimentação das partículas de prata na superfície do carreador durante um processo de epoxidação. em particular, as cavidades na superfície do carreador alumina efetivamente envolvem e/ou ancoram partículas de prata e previnem as mesmas de movimentação adicional.
