Abstract
Pyrolysis of a polymeric urban disposals mixture is studied in this paper. A polymer mixture is degraded over a silica–alumina catalyst using a semi-batch laboratory reactor operating under isothermal and constant pressure conditions. The effects of catalyst on the distribution of oil products, catalyst ratio, and mass fraction of feedstock are investigated. The liquid samples were analyzed by gas chromatography method. The liquid products, collected at optimum reaction condition at 430 °C, catalyst to polymer ratio 40 %, are distilled at different temperatures in order for light and heavy fractions to be separated. Octane number, color, reid vapor pressure, specific gravity, and density are analyzed to determine several physical properties of the liquid products at optimum reaction condition. Finally, using Arrhenius’s law, a kinetic model is developed to determine the reaction kinetic parameters.
