Co-pyrolysis of wood biomass and synthetic polymers mixtures. Part III: Characterisation of heavy products

The chemical composition of heavy liquids (b.p.>180 °C) obtained by co-pyrolysis of polyolefins/wood biomass mixtures in autoclave conditions under inert atmosphere was investigated by FTIR, 1H NMR, GC-MS, high performance TLC combined with densitometry techniques. The preliminary separation of heavy liquids into different fractions by open LC and TLC methods had been used. Some perspectives of polymer and biomass thermal conversion during co-pyrolysis process were discussed.
