This paper describes non-catalytic pyrolysis of plastic waste materials. Three types of waste plastics were used in this study: polystyrene (PS), polyethylene (PE) and polypropylene (PP). Under pyrolysis conditions, plastic wastes can be decomposed into three fractions: gas, liquid and solid residue. The liquid products are usually composed of higher boiling point hydrocarbons. In order to obtain useful gasoline-range hydrocarbons from the pyrolytic oil, fractional distillation is preferred for product separation. More valuable chemical raw materials including benzene, toluene and other condensed aromatic hydrocarbons may be obtained by refining the pyrolytic oil. The results showed that waste PS yielded higher liquid, and waste PE and PP yielded higher gaseous products. The dominant pyrolytic liquid product of PS waste was styrene. (C) 2004 Elsevier B.V.
