Abstract: 
Celtis mildbraedii sawdust (CMS) from Ghana was characterised to investigate its suit-ability with polyethylene terephthalate (PET) for syngas production via co-pyrolysis. The physical and chemical properties assessed include proximate and ultimate compositions, pH value, higher heating value (HHV), and lignocellulosic composition. Also, the ther-mal behaviour at different heating rates (5, 10, and 20 K/min) and qualitative predic-tion of organic compounds of CMS were examined using thermogravimetric analysis (TG/DTG) and NIR spectroscopy techniques, respectively. Results of proximate analysis (moisture = 17.15 +/- 0.0 wt.%, ash = 1.13 +/- 0.4 wt.%, volatile matter = 68.39 +/- 0.4 wt.%, fixed carbon = 13.33 +/- 0.8 wt.%); ultimate analysis (C = 48.51 wt.%, H = 6.66 wt.%, N = 0.51 wt.%, S = 0.02 wt.%, O = 44.30 wt.%); pH values (cold phase = 7.60, hot phase = 6.30); HHV (15.37 - 18.03 MJ/kg); and lignocellulosic composition (extrac-tives = 13.80 +/- 0.57 wt.%, hemicellulose = 21.95 +/- 3.89 wt.%, lignin = 17.35 +/- 0.35 wt.%, cellulose = 46.90 +/- 2.97 wt.%) were obtained. The maximum mass loss was 83.48% at 289.8 degrees C at 5 K/min. It was concluded that CMS is a highly potential biomass resource for syngas production with an empirical formula of CH1.64O0.69N0.009S0.0 0 01. (c) 2022 The Author(s).
