ABSTRACT
The need to produce enhanced pyrolytic oil from biomass for specific applications is necessary to achieve sustainable energy and chemicals. Bottled water and beverage waste plastics are common terrestrial and aquatic pollutants. This research aimed to produce pyrolytic oil from the Hyphaene thebaica shell-waste plastics and evaluate its pyrolytic oil compositions. The composite of the Hyphaene thebaica shell-waste plastics (HTS-WP) was prepared and characterized using thermogravimetric analysis to determine the devolatilisation behaviour. The HTS-WP was pyrolyzed, and pyrolytic oil was obtained. The pyrolytic oil was characterized using Fourier Transform Infra-Red (FTIR) and Gas Chromatography-Mass Spectrometer (GC-MS). The results indicate the presence of hydrocarbons, aromatics, phenols, organic acids, ketones, and aldehyde in the pyrolytic oil from HTS and HTS-WP. The acid is mainly 9-octadecenoic acid. The co-pyrolysis influenced the pyrolytic oil composition by reducing the acid from 53% when the biomass alone was pyrolysed to 32%, for co-pyrolysis of HTS-WP, while the hydrocarbons significantly increased from 1.8% to 16%. This indicates that the co-pyrolysis is effective in upgrading the biofuel from the pyrolysis of biomass, specifically, Hyphaene thebaica shell. The resulting pyrolytic oil from co-pyrolysis demonstrates that co-pyrolysis effectively enhances fuel quality relative to biomass-only.
