“…On the other side, raising the rate of heating diminished the yield of BC and increased the yield of gaseous products. This outcome may belong to the rapid depolymerization of the solid biomass to primary volatiles 99 . The obtained consequences were in line with those established by other researchers 76,100–102 …”

Mandarin (Citrus reticulata) seeds were exploited as possible nonedible feedstock for the synthesis of liquid biofuels, namely, biodiesel and bio‐oil via alkali–alcoholysis and pyrolysis routes, respectively. The alkali–alcoholysis reaction of mandarin seed oil with an equivalent mixture of methanol–ethanol alcohols was examined and optimized by analysis of variance (ANOVA). The best experimental yield of biodiesel (95.55 ± 1.55 wt.%) was comparable with the predicted yield (95.0 wt.%). Also, analysis by one‐way ANOVA showed that the selected variables were statistically significant. The 1H NMR spectroscopy asserted the transformation of the oil to biodiesel. Also, the evaluated properties of the biodiesel were in the range given by ASTM D6751 standards. The mandarin citrus seeds have also subjected to the thermal pyrolysis process in a fixed‐bed reactor to obtain bio‐oil and bio‐char. The influence of the pyrolysis temperature, time, feed particle size, and heating rate on the bio‐oil yield was optimized. The highest yield of bio‐oil (52.34 ± 1.25 wt.%) was attained at 475°C for 60 min using 70 mesh particle size of the feed with a heating rate of 20°C/min. The bio‐oil was analyzed by Fourier transform infrared spectroscopy (FTIR), 1H NMR spectroscopy, and ultimate analysis. The bio‐oil derived from MCS has an empirical formula of CH1.88 O0.16 N0.012 S0.0005 with 37.96 MJ/kg of heating value. The elevated carbon level, low oxygen content, and high calorific value (25.45 MJ/kg) of the attained bio‐char suggest its suitability as a solid fuel. Also, the obtained bio‐char can be utilized for preparing carbon adsorbent as a result of its good surface area.

“…These results are due to the high‐molecular‐mass compounds of the bio‐oil compared to that of diesel fuel. The flashpoints of the BAS‐derived bio‐oils were relatively identical, at the same time comparable to that of diesel fuel and bio‐oils obtained from the pyrolysis of hyacinth 40 and alligator weed 44. This suggested that the bio‐oils could be attractive feedstocks for transportation fuel.…”

Intermediate Pyrolysis of Desert Date Shell for Conversion to High‐Quality Biomaterial Resources

et al. 2022

Intermediate pyrolysis on desert date (Balanites aegyptiacus) shell (BAS) was accomplished for the first time to authenticate the biomass potential for producing quality biomaterials such as bio-oil and biochar. Fourier transform infrared spectroscopy (FTIR), elemental analysis, and gas chromatography-mass spectrometry (GC-MS) were employed to examine the compositions of the resultant biooil. The FTIR spectrum revealed the functional groups of oxygenated compounds like aldehydes, alcohols, phenolics, acids, and esters in the bio-oil. GC-MS confirmed that the bio-oil has diverse compositions of oxygenated compounds rich in acids, phenolics, and benzene derivatives. From the ultimate analysis, the bio-oil had a higher carbon content and a lower oxygen content than the corresponding BAS sample. The calorific values, by comparison, were higher than that of the BAS sample but lower than for fossil fuels. The favorable outcomes from the characters of the bio-oil and biochar suggested that BAS can be an attractive feedstock to produce high-value biomaterials.

“…The primary constituent of biochar is carbon, followed by hydrogen, oxygen, ash content and trace amounts of nitrogen and sulphur. The elemental compositions of biochar generally changes with the nature of feedstock and pyrolytic conditions such as carrier gas flow rate, catalyst, heating rate, pressure, reactor bed height, particle size, residence time and temperature [3,[6][7][8][9].…”

Organic matter derived from plants and animals are known as biomass. It has a great potential to be used as an alternate source of energy by employing thermochemical conversion techniques. Among the available techniques, pyrolysis is considered to be the most efficient technique used for the conversion of biomassbased waste into value-added solid, liquid and gaseous products through heating in an oxygen-limited environment. Biochar (solid fuel) is a carbonaceous material and has multiple applications in various fields such as soil health, climate stability, water resource, energy efficiency and conservation. The yield of biochar depends on organic constituents of biomass and the pyrolytic process parameters such as temperature, time, heating rate, purging gas, particle size, catalyst, flow rate, pressure and types of pyrolysis reactors. Suitable conditions for biochar production were observed to be slow pyrolysis, low carrier gas flow rate, acid-catalysed biomass or biomass mixed with some inorganic salts, low heating rate, large particle size, high pressure, longer residence time, low temperature, feedstocks with high lignin content and pyrolysis reactors with lower bed height. Thermal conversion of biomass could be a possible sustainable alternative to provide economically viable, clean and eco-friendly solid fuel.
