✦ Synopsis

This study investigated the pyrolysis of automobile shredder residue (ASR) using a laboratory scale screw kiln reactor with a feed rate of about 100 g h ', Pyrolysis at temperatures between 500 and 750" resulted in the production of gas, liquid and solid fractions with hydrocarbon yields of the organic fraction present in the feed increasing from 60-85% with increasing pyrolysis temperature.

While the hydrocarbon pyrolysis product yield increased with pyrolysis temperature, the yield of the oil fraction was higher at the lower pyrolysis temperatures.

The composition of the pyrolysis oil also changed with pyrolysis temperature, containing larger quantities of aliphatic compounds at the lower temperatures than at higher temperatures where aromatics were the major compounds.

Many of the liquid pyrolysis products have been identified including polycyclic aromatic hydrocarbons as well as organo-nitrogen, sulfur and chlorine compounds. The data obtamed here have been compared with that from a process using short pyrolysis residence times.
