Abstract

Patente de Invenção: <B>"PROCESSO PARA A REGENERAçãO DE CATALISADORES DE SUPORTE RECOBERTOS COM PARTìCULAS DE OURO PARA A OXIDAçãO DE HIDROCARBONETOS INSATURADOS"<D>. Descreve-se um processo para a regeneração de um catalisador revestido com partículas de ouro, à base de dióxido de titânio ou de hidrato de óxido de titânio, para a oxidação de hidrocarbonetos insaturados, na fase de gás, caracterizado pelo fato de que o catalisador é regenerado, em sua atividade catalítica, por colocação em contato com água ou ácido diluído ou uma solução de hidroperóxido diluída. Além disso, descreve-se a aplicação desses catalisadores regenerados para a epoxidação de eteno, propeno, 1-buteno ou 2-buteno, na fase de gás.
