Abstract
PROCESSO PARA MANTER A MANOESTRUTURA DE PARTÍCULAS DE CATALISADOR ANTES DA SÍNTESE DE MANO-MATERIAIS CARBONÁCEOS. A presente invenção refere-se a um novo processo, um óxido de metal é aquecido em um reator em 20% de gás H2 a uma taxa de aquecimento de 5 graus Clmin até 450 graus O; o catalisador é mantido a esta temperatura por 30 minutos, seguido de exposição a 10 a 20% CO por mais 30 minutos; e em seguida resfriado para a temperatura ambiente. O catalisador resultante é então usado para a síntese de fibras de carbono a 550 e 600 graus O. Em uma outra modalidade o catalisador depois de produzido é removido do reator, e uma nova batelada de catalisador de óxido de metal é colocada no reator para proporcionar um processo de produção continua.
