  • Patent number: 8168839
    Abstract: Certain examples relate to methods of continuously cracking waste rubber or plastics and apparatuses related to the same, to produce oil from waste rubber or plastics. Raw materials comprising a catalyst and rubber or plastics may be extruded in order to separate the air or to prevent oxidization. The raw materials are transported into the cracking chamber, and moved from the inlet to the discharge hole. After the cracking process is finished, the products are discharged automatically through the discharge hole. The separation of air and oxygen in the inlet and discharge hole of the cracking chamber can avoid dangers caused by oxygen entering the cracking chamber, and realize industrial production with continuous feedings. The ratio of the oil can be raised from 19% to 45%-48%, and the loss of production equipment reduced. Production costs are reduced, safety measurements improved, and continuous production is realized.

  • Patent number: 7375255
    Abstract: The present invention provides a pyrolysis system and method thereof which are capable of converting an entire rubber tire into several energy resources in an environmentally-friendly manner. The system includes a tire transporting unit, a waste to energy conversion unit, and a energy collection unit. The waste to energy conversion unit includes a conversion housing having a reaction chamber for receiving the rubber tire for pyrolysis processing to decompose the rubber tire into fuel oil, methane gas and carbon black, while metal wire from the rubber tire are resided for recycling use.

  • Patent number: 4324620
    Abstract: A pyrolyzing apparatus having a pyrolysis fluidized bed chamber and an incineration fluidized bed chamber or chambers each directly adjacent and communicated with the pyrolysis fluidized bed chamber through an opening or openings in a partition wall above a common perforated bottom plate, the respective levels of the fluidized beds being controlled by regulating the pressure(s) in free board(s) of the fluidized bed chambers.

  • Patent number: 4082615
    Abstract: A thermal decomposition process and apparatus of the fluidized bed type for organic solid materials, particularly organic solid waste material contained in urban rubbish comprising a fluidized bed thermal decomposition furnace, the interior of which is divided by a partition plate into two zones, namely a first zone for thermally decomposing the organic solid waste material in the absence of oxygen and a second zone mainly for burning the carbonized material produced as a result of thermal decomposition of the organic solid waste material. Non-condensable components of the gas resulting from the thermal decomposition of the organic solid waste material are recirculated as fluidizing gas into the first zone, while air is used as the fluidizing gas for the second zone. Heat for the thermal decomposition in the first zone is obtained from the combustion in the second zone and transferred by the intertransfer of fluidized solids between zones beneath the partition plate.
