Abstract

The pyrolysis of polyvinylchloride (PVC) was studied in a quartz reactor with and without the addition of metal chlorides as catalysts. The results indicated that the addition of metal chlorides such us ZnCl<inf>2</inf> or BaCl<inf>2</inf> decreased the temperature of dehydrochlorination of PVC. The introduction of H<inf>2</inf> in pyrolysis enhanced the degradation of PVC at 400°C or higher and decreased the amount of solid residue. Gas chromatography/mass spectroscopy analysis indicated that Zn and Ba chlorides reduced the formation of high molecular weight products.
