Abstract

The investigation of the characterization of Adansonia digitata biomass from pyrolysis in a fixed-bed tubular carbon steel reactor at temperatures of 400? to 700?. Firstly, proximate, ultimate, and heating value analyses of the raw biomass were obtained prior to experimental runs via the fast pyrolysis process; thereafter, the quality of the bio-oil and biochar yields for bioenergy and industrial applications was investigated using the following analyses: higher heating values (HHV), lower heating values (LHV), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR). Optimum bio-oil (52.70 wt%) and bio-char (40 wt%) yields were obtained at temperatures of 500 and 400?, respectively. GC-MS analysis of the yielded biooil revealed a higher percentage of oleic acid, phenol, methanol, and ketone among the fuel compositions, whereas the bio-oil chemical composition includes carbon (70.99%), hydrogen (13.40%), nitrogen (0.54%), oxygen (15.01%), and sulfur (0.06%), flash (81) and pour points (-7) for bio-oil with HHV (30.75 MJ/kg) and LHV (27). The results obtained demonstrated that the properties of products can serve as a waste management strategy, sorbent, soil enhancer, and biofuel industry application.
