Abstract: Polyvinyl chloride (PVC) is rated second only after poly ethylene (PE) as volume leader in the plastic industry. Waste PVC poses serious environmental problem because of its high chlorine content (56%) and non-biodegradable nature. Treatment of waste PVC by incineration or pyrolysis produces toxic chloro emissions which adversely affect environment, ecology and human health. Catalytic degradation of PVC was performed using a fluidized bed reactor with catalyst such as Fe2O3, ZSM-5, Pd/Aℓ2O3 in the temperature range 100 – 430°C. Arrangement was made to adsorb liberated chlorine on CaCO3. The effect of feed to catalyst ratio and temperature were evaluated for the maximum liquid yield. Maximum liquid yield of 12.17% was obtained using catalyst ZSM-5 at 3:1 feed to catalyst ratio.
