Abstract

''PROCESSO PARA A PREPARAçãO E PARA A PRODUçãO DE UM CATALISADOR SUPORTADO DE PALáDIO-OURO, E, CATALISADOR SUPORTADOR DE PALáDIO-OURO''. é fornecido um processo melhorado para a produção de catalisadores suportados de paládio-ouro de atividade elevada e seletividade elevada. O processo envolve a calcinação do suporte impregnado com um sal de paládio e um sal de ouro em uma atmosfera não reduzida e em uma temperatura variando de 100‹C a 600‹C antes da redução dos metais. Os catalisadores da invenção são úteis para a aprodução de acetato de vinila na fase vapor pela reação de etileno, ácido acético e oxigênio.
