Obtaining Hydrocarbon Rich Bio-Oil Via Catalytic Co-Pyrolysisof Plastic Wastes And Spirulina Sp. Microalgae

Abstract

Synergic effect of microalgae, polystyrene and low density polyethylene on the co-pyrolytic bio-oil product yield and composition were investigated. Spirulina in powder form was used as microalgae source, while the mixture of polystyrene and low density polyethylene were used as the source of plastic wastes. All experiments were done with 25 mL/dk carrier gas flowrate, 10 °C/min heating rate and 60 min duration in semibatch reactor.In the thermal co-pyrolysisexperiments, it was studied under different algae to plastic wastes feedstock ratio (1/1, 1/2, 2/1) at 570 °C. Catalytic co-pyrolysis was carried out with 1/30, 1/15, 1/10 catalyst to feedstock ratio and 10 % wt./wt. metal doped ZSM-5. BET, SEM and XRF analysis were done for the catalysts. Product yield were calculated and bio-oil product were characterized by GC-MS.
