Refinery Oil Fraction Fuels Obtained from Polyethylene Catalytic Cracking Employing Heteropolyacid-MCM-41 Materials

We report the thermal and catalytic decomposition of low density polyethylene (LDPE) as a recycling route of plastic solid waste. The reaction system consisted of a fixed-bed reactor at a 450 °C reaction temperature and a 40 min reaction time. Tungstophosphoric acid (H3PW12O40)-functionalized ordered mesoporous materials MCM-41 were employed as catalysts. Results show that using this technical approach, on one hand, environmentally unfriendly waste can be disposed and, on the other hand, valuable and widely used fuels can be obtained.
