PURPOSE: To obtain a method for producing the infusible products of thermoplastic fine particles useful for the production of activated carbon, capable of rapidly and uniformly producing the infusible products in good productivity, while preventing the mutual fusion of the fine particles due to their melting. CONSTITUTION: This method for producing the infusible products of the thermoplastic fine particles comprises adding medium particles having a larger average particle diameteer than the thermoplastic fine particles to the thermoplastic fine particles having an average particle diameter of 1-100μm, and subsequently bringing the thermoplastic fine particles into contact with an oxidizing gas, while vibrating the fine particles under a flow condition. And the method for producing the activated carbon comprises granulating the obtained infusible fine particles and subsequently activating the obtained granules. |
