“…High carbon content is expected to increase the heating value of woody biomass. The mean value of the carbon content obtained (45.54 ± 0.02) agreed with the reported results in the literature putting the carbon content of wood between 45 and 50 % and 0.01 % of Sulphur, confirming biomass energy is environmentally friendly [38][39][40][41]. Table 4 presents comparison of the HHVs obtained from experimental analysis to that obtained from correlations by ultimate analysis (Eq.…”

“…If the five selected waste saw-dust samples are further treated to greater pyrolysis temperatures, as shown in Table 2 with the average volatile matter of 75.26 + 0.14 and low ash content of 1.64 + 0.16-1.73 %, there is possibility for a higher yield of bio-oil from the fuel wood samples. When compared to fixed carbon content available in wood residues (11-15 %), a significant percentage of fixed carbon (14.09-14.80 %) obtained in the wood samples for this study indicates high energy content potential in the wood samples [38,39]. The wood samples' low ash content (1.08-1.93 %) is a desirable characteristic.…”

Using agro-industry residues as an energy source has been essential to replacing traditional fuels and developing resilient and sustainable socio-economic scenarios. The present work uses sunflower stem and corn cob as pyrolysis feedstocks to track the thermochemical synthesis of the renewable energy products bio-oil, biogas, and biochar and their relation to biomass components. Characterization and thermal degradation of biomass samples were provided by determining the elemental and lignocellulosic composition and thermogravimetric analysis. The three main products from pyrolysis conducted at 500 °C (biochar, bio-oil, and biogas) were evaluated for their yield, and the bio-oils were also characterized by Fourier transform infrared elementary analysis and gas chromatography/mass spectrometry. The obtained bio-oils showed similar profiles, presenting phenol and carboxylic acids as the major classes and the presence of alcohols and aldehydes. Therefore, outcomes allowed for understanding the thermal behavior of biomass components and the impact of different input materials on pyrolysis of product yield and properties.

“…Hence, leading to extensive equipment maintenance [37]. Also, the low ash content at 1.35 wt% at 500℃ during the pyrolysis process indicates a significant bio-oil yield, as the low percentage of ash content reduce the catalytically cracking of the bio-oil into NCG [38,39]. The wood samples had a larger proportion of fixed carbon (19.41 wt%) than the fixed carbon in wood residues (11-15 wt%), indicating that they contained more energy and had a higher heating value of 16.27 MJ/kg [4,37].…”

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.
