Abstract

"REATOR DE PASTA FLUIDA, E, PROCESSO PARA REJUVENESCIMENTO DE UM CATALISADOR DE SìNTESE DE HIDROCARBONETO REVERSIVELMENTE DESATIVADO". Um catalisador em partículas, reversivelmente desativado, em uma pasta fluida em um pasta fluida em hidrocarboneto é rejuvenescido em uma pasta fluida rejuvenescida, pela circulação da pasta fluida para uma massa de pasta fluida através de (i), uma zona de gás de desengajamento, para remover bolhas de gás da pasta fluida, (ii) uma zona de catalisador de rejuvenescimento em que um gás do catalisador rejuvenescido faz contato com o catalisador na pasta fluida para rejuvenescer a mesma e formar uma pasta fluida de catalisador rejuvenescido, e (iii) retorno para a massa de pasta fluida. Remoção de pelo menos uma porção das bolhas de gás aperfeiçoa o processo de rejuvenescimento.
