Prolysis of Polystyrene Wastes Of Pyrolytic-Oil Recovery

Abstract

Polystyrene wastes was pyrolyzed in a directly heated fix-bed reactor under nitrogen atmosphere. The weight loss of Biomass at different temperature was deducted from the thermogravimetric analyzer (TGA). From TGA results, it was inferred that maximum devolatilization takes place at pyrolysis temperature of 4000C. the effect of pyrolysis temperature on the pyrolysis of the PS were also studied in a fixed bed pyrolysis reactor. Pyrolysis runs were performed using reactor temperatures between 4000C, 4500C and 5500C with heating rateof about 100Cmin-1. As the pyrolysis temperature was increased the percentage mass of char decreased while gas product increased. The product yields were significantly influenced by the processing conditions. The pyrolytic-oil obtained at 4500C, at which the liquid product yield was maximum, was analyzed. Keywords: wastes, polystyrene, fixed-bed reactor, pyrolytic-oil, fuel.
