Abstract

"PROCESSO PARA REDUZIR A ETAPA DE PRé-REDUçãO PARA CATALISADORES PARA SìNTESE DE NANOCARBONO". A presente invenção refere-se a um processo para eliminar ou reduzir a etapa de pré-redução para catalisadores para a síntese de nanocarbono primeiro aquecendo um óxido de metal a 5<198>C/min para 350-500<198>C durante 70-90 minutos sob 10-20% de hidrogênio; opcionalmente reter a temperatura durante 10 a 60 minutos; depois iniciar fluxo de carga de alimentação carbonácea.
