Research will be conducted by HiChem Corporation, to develop a new technology for pyrolysis of scrap tires. Disposal of used tires is a big problem in the world, especially USA, since more than 2.5 million tires are discarded each year. Most of these tires are disposed in landfills. Pyrolysis of scrap tires helps to recover and reuse most of the valuable chemical available in tires. Pyrolysis of scrap tires under inert atmospheres produces reusable gas, oil, and char. However, at present, these products have low market value because of their poor quality. Therefore, disposal of the tires by pyrolysis is marginally attractive as a business venture. The proposed research aims to prove that pyrolysis products produced by the HiChem process will produce reusable oil and char of higher quality. These products will be competitively marketable in the existing market with an advantage of low priced feedstock. The researchers also aim to show how to significantly shift the proportionality of the byproducts (carbon and oil) produced using the HiChem process to a higher quality and quantity product.
