  • Another object of the invention is to provide apparatus for producing high quality carbon and synthesis gas from waste automotive tires.
  • This invention is a method and apparatus for thermally processing waste automotive tires and to efficiently extract non-condensable synthesis gases rich in hydrogen and carbon monoxide for uses such as; a feedstock for primary chemical processes, a clean fuel gas or (via sieving), a source of higher value hydrogen, carbon monoxide or carbon dioxide gases.
  • the process can be controlled to achieve higher or lower production rates of either synthesis gas or carbon char. Higher char production rates come at the expense of lower synthesis gas production rates and vice-versa.
  • the apparatus of this invention is a single rotating reactor that has two contiguous hearth reaction areas, i.e., a drying and volatizing area and a synthesis gas reformation area.
  • the two areas are separated only by the induced and opposing atmospheres generated by the process burners that fire from each end of the disclosed reactor. Gases and fumes formed in the drying and volatizing area flow co-currently with the direction of the burner products induced by the feed-end process burner. Cracking, dissociation, and/or reformation of vaporous hydrocarbon gases issuing from the feed-end of the reactor begins when these evolved gases enter the influence of the counter-current high temperature atmosphere induced by the discharge-end process burner.
  • High turbulence results in the contact zone in which gases from the feed-end collide with the counter-current products-of-combustion from the discharge-end process burner.
  • the high turbulence, induced by the process burner gases greatly enhances cracking, dissociation and/or refo ⁇ ning of the complex hydrocarbon gases and reduces such gases to more simple molecular forms.

  • Both the feed-end and discharge-end burners are designed to operate specifically with a fuel gas, oil, carbon fines or syngas as the combustion energy source, and near-pure oxygen is provided as the oxidizing agent. Air is not used in either burner; thus, the level of nitrogen in the product synthesis gas is exceptionally low.

  • the hot DRI is taken directly to the melting operation in insulated canisters to conserve as much latent heat as possible.
  • the overall concept is to reduce thermal energy input to the lowest possible level.
  • Carbon based DRI has several advantages. It can be discharged hot from the RHF and still contain a high and controllable percentage of carbon. Also, carbon based DRI is advantageous in steelmaking in that it is possible to control the amount of carbon remaining in the DRI pellet after reduction has occurred.
  • the DRI process is a solid carbon based system.
  • almost any reasonable source of carbon can be used, such as carbon from shredded automobile tires, municipal and industrial solid waste, or other biomass.
  • Other suitable sources are coal, petroleum coke, coke breeze, lignite or charcoal fines.
  • Each potential source must be evaluated for its overall contribution to the cost per iron unit of the finished DRI product.
  • iron bearing metallurgical wastes are proposed as the source of iron units, the average analysis of these wastes is a known quantity in contrast to a questionable positive analysis of steel scrap. This known analysis enables steel mills using such materials to produce consistently cleaner steel, from a contaminant standpoint, than a conventional scrap-based mill. After beginning operation in a facility using iron ore and carbon as the primary raw materials, then operators may substitute the locally available wastes to the fullest extent possible.
