Abstract: Purified carbon black carried by a screw conveyer, while being subject to preheating treatment, is transported to a microwave heating zone where it is heated to a temperature between 250° C. and 400° C. and subsequently, it is sent into a flow-type steam activation furnace there under the passage of steam and at a temperature inside the furnace maintained at 700° C. to 900° C. the carbon black is heated and activated to form a powdery activated carbon. This novel method for the production of activated carbon with high added value from carbon black is a continuous process of high productivity especially suitable for carbon black recovered from the heating and splitting decomposition processes of waste tires, waste plastics and the like.

Abstract: A method and device is provided which is capable of producing gasified substance and solid-shaped carbonized substances from solid-shaped wastes such as waste tyres by a series of heating, dry distillation and splitting decomposition. After discharging out from the bottom of a splitting decomposition reactor, the solid-shaped carbonized substances are subject to a series of treatments: water washing, magnetic separating, alkaline cleaning and acid pickling (treatment) to separate out iron wire and to remove heavy metal-bearing ash contents. The carbonized substances are next pulverized to the desired particle size so that highly purified carbon black is formed. Subsequently, the carbon black granules are led into an activation furnace and are heated and activated at the atmosphere of steam being passed in to produce powder particulate activated carbon. On the other hand, from the gasified substance produced by-products of the combustible oil and gas are respectively formed.
