Abstract

PURPOSE: To produce high-purity C in high efficiency at a low cost by fluidizing an iron powder layer with a by-product gas composed mainly of CO while controlling the layer to a specific temperature, thereby forming fine carbon powder on the surface of the iron powder.
CONSTITUTION: An iron powder layer in a fluidizing furnace is controlled to 400-600°C. A by-product gas composed mainly of CO and generated from a refinery furnace or melting furnace is introduced into the fluidizing furnade to fluidize the fluidizing layer and cause the reaction 2CO → CO2+C. The produced fine C powder is separated and recovered from the surface of the iron powder.
