Reduction of Polymer Waste Pyrolysis Fractions over Pt/Al₂O₃with Methanol Decomposition Hydrogen to Obtain Fuel-Grade Hydrocarbons

Abstract

The hydrogenation under atmospheric pressure of waste polymer pyrolysis fractions over 5% Pt/γ-Al2O3with hydrogen from the catalytic decomposition of methanol over 5% CoO/SiO2has been performed. A 97–100% C=C bond hydrogenation selectivity was achieved at 300°C. The obtained saturated C6–C20and C20–C30fractions can be applied as blending material for fuels and lubricants, respectively, or as hydrocarbon feed. The applied coupled catalytic system exhibited high efficiency at 300°C for at least 5 hours.
