Implication

Experimental study demonstrates fuel synthesis and engine performance from catalytic plastic pyrolysis, indicating trade-offs between energy efficiency and increased exhaust emissions.

Key Points

Evaluate the fuel quality, engine performance, exergy efficiency, and emission profile of waste-plastic pyrolysis products upgraded using different catalysts.
Conducted pilot-scale pyrolysis and ex-situ catalytic cracking of waste plastic bags at 400–440 °C using ZSM-5, dolomite, and kaolin catalysts.
Characterized catalyst surfaces and product reaction pathways using BET surface area analysis, SEM imaging, and GC–MS.
Assessed engine performance, exergy losses, and exhaust emissions using a 20% blend of gasoline-range plastic pyrolysis oil (G-PPO).
Maximum liquid yield occurred at 420 °C, with ZSM-5 yielding aromatic gasoline-range oil having a high heating value of 44.5 MJ kg–1, while dolomite favored diesel-range cycloalkanes and kaolin suppressed wax formation.
Exergy analysis showed ZSM-5-derived fuel achieved the lowest exhaust exergy and irreversibility losses during engine operation.
Engine testing with a 20% G-PPO blend increased brake thermal efficiency under load, but produced higher NOx and particulate emissions compared to standard commercial gasoline.
