Reduction of Polymer Waste Pyrolysis Fractions over Pt/Al2O3 with Methanol Decomposition Hydrogen to Obtain Fuel-Grade Hydrocarbons

The hydrogenation under atmospheric pressure of waste polymer pyrolysis fractions over 5% Pt/γ-Al2O3 with hydrogen from the catalytic decomposition of methanol over 5% CoO/SiO2 has been performed. A 97–100% C=C bond hydrogenation selectivity was achieved at 300°C. The obtained saturated C6–C20 and C20–C30 fractions 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.
