Implication

Experimental study demonstrates that adding polypropylene to biomass co-pyrolysis boosts bio-oil heating value and reduces density, indicating improved fuel properties for waste-to-energy conversion.

Key Points

To evaluate the effect of varying polypropylene waste fractions on the fuel properties and chemical composition of bio-oil and biochar derived from co-pyrolysis with lignocellulosic biomass.
Conducted non-catalytic co-pyrolysis of Delonix regia wood and Polyalthia longifolia leaves with 0 wt.%, 10 wt.%, 30 wt.%, and 50 wt.% polypropylene at 600 °C in a tubular reactor.
Characterized organic bio-oil fractions and biochar using FTIR, 1H NMR, TGA, XRD, and FESEM.
Calorific value of the organic bio-oil fraction increased from 22.556 MJ/kg at 0 wt.% polypropylene to 34.06 MJ/kg at 50 wt.% polypropylene, while biochar displayed a mixed calorific trend.
Bio-oil density decreased from 973 kg/m³ to 816 kg/m³ and pH increased from 4.31 to 4.97 as polypropylene content rose to 50 wt.%, accompanied by higher yields of alkanes and aliphatic compounds.
