PROBLEM TO BE SOLVED: To provide a mass-producible method for producing carbon fine particulates.SOLUTION: In a method for producing carbon fine particulates from a lignin-containing liquid, a first dewatered cake C1 is obtained by acidifying the lignin-containing liquid and succeedingly conducting dehydration, a second dewatered cake C2 is obtained by slurrying the first dewatered cake C1, advancing acidification, and succeedingly again conducting dehydration, inorganic salt-containing fine particulates are obtained by slurrying the second dewatered cake C2, mixing the slurry with an inorganic salt X and succeedingly conducting liquid droplet formation and drying, and the carbon fine particulates are obtained by thermal decomposition of the inorganic salt-containing fine particulates and succeedingly removing the inorganic salt X therefrom. |
