摘要：
In the present paper, LDPE has been pyrolysed in a 1 m length semi pilot reactor at temperature range 550-650 degrees C for around 2 h. Commercial bentonite, kaoline, silica Gel and activated charcoal have been used as catalyst. Liquid, gas and solid fractions (residue) were quantified. Effects of pyrolysis temperature and catalysts on liquid product were investigated. It was found that using catalyst gave shorter dripping time and this dripping started at a lower temperature. PIONA analysis of liquid product has been carried out and the highest percentage of olefins was found on using bentonite as a catalyst.
