Abstract

"PROCESSO PARA A PREPARAçãO DE UM CATALISADOR MICRO-ESFEROIDAL". Processo para impregnação de partículas de suporte de catalisador micro-esferoidais com pelo menos um composto de um metal nobre do Grupo VIII cataliticamente ativo, processo este que compreende as etapas de: (a,) impregnar as partículas de suporte micro-esferoidais pela técnica de umidade incipiente com uma solução aquosa de pelo menos um metal nobre do Grupo VIII cataliticamente ativo, enquanto agitando as partículas de suporte, e (b<39>) secar as partículas de suporte impregnadas produzidas na etapa (a<39>) enquanto agitando as partículas de suporte impregnadas. As partículas de suporte micro-esferoidais são preferivelmente de sílica, alumina, zircónia ou suas misturas. Quando o metal nobre do Grupo VIII cataliticamente ativo for paládio, o processo pode ser usado para preparar um catalisador ativo para a acetoxilação de base fluida de etileno para produzir acetato de vinila.
