  • Publication number: 20170247618
    Abstract: Provided is a thermal decomposition method that allows efficient thermal decomposition of an organic substance such as a plastic to produce gas and oil with high heating value and with which a large amount of the organic substance can be processed. The method includes mixing the organic substance with an organic substance decomposition catalyst, forming the mixture to produce a composite agglomerated material, and thermally decomposing the organic substance by placing the composite agglomerated material in a thermal decomposition furnace. The maximum catalytic effect can be obtained since the organic substance and the catalyst are close to each other in the composite agglomerated material. Since the catalyst has thermal conductivity higher than that of the organic substance, the temperature rising rate of the organic substance can be increased.

  • Publication number: 20030021991
    Abstract: Waste plastics including solid plastics, thin plastics, and foamy plastics are fed into a ring die of an extrusion molding machine. The waste plastics are either semi-melted or melted, and are then extruded onto an outer circumferential surface the ring die through die cavities. Thus, granular plastic moldings are extruded onto the outer circumferential surface of the ring die through the die cavities, and are then cut or scraped from the outer circumferential surface of the ring die. The pellets have a melt-solidified surface, and have a strength sufficient to reach a predetermine zone in a raceway of a furnace and a grain diameter sufficient to be fed at a velocity higher than a limiting velocity thereof during injection to the furnace.
