To provide the production method of a spherical phenolic resin granule, by which the average particle diameter of fine spherical phenolic resin particles can be controlled and spherical phenolic resin particles can be efficiently recovered without performing centrifugal separation, and to obtain a fine spherical carbon material and an activated carbon material.
The production method of a spherical phenolic resin granule includes steps of: making phenols including polyvalent phenols be subjected to condensation reaction with aldehydes in the presence of a condensation catalyst in an aqueous medium to obtain a spherical phenolic resin dispersion liquid in which a spherical phenolic resin is dispersed; adding an organic coagulant to the spherical phenolic resin dispersion liquid to obtain a coagulated product; separating and recovering the coagulated product; drying the separated and recovered coagulated product to obtain a dried product; mixing the dried product with a binder to obtain a mixture; and granulating the mixture to obtain a granule. The production method of a carbon material using the above spherical phenolic resin granule, and the production method of an activated carbon material using the spherical phenolic resin granule are also disclosed.
