Abstract
Un procedimiento para eliminar o reducir el paso de pre-reducción en catalizadores para síntesis nano-carbónica, que comprende en primer lugar calentar un oxido de metal a 5°C/min hasta 350-500°C durante 70-90 minutos en hidrógeno al 10-20%; opcionalmente mantener la temperatura durante 10 a 60 minutos, luego iniciar el flujo de carga carbonacea.
