“…All the samples have similar spectra except for biochar produced under 700°C and 800°C. The peak between 3200 cm -1 to 3700 cm -1 attributes to the hydroxyl (O-H) stretching, which might indicate the presence of moisture in biochar [20]. The intensity of this peak does not differ much, in good agreement with the reported moisture content via proximate analysis in Table 2.…”

“…Another sharp peak was found at 1586 cm -1 on the biochar produced at 800°C, which was absent in all other samples. This absorption band is mostly characterized as the stretching of aromatic C=C bonding and carbonyl group (C=O) which refers to the combination of both phenyl and carbonyl compound in lignin, as well as dehydration and cyclisation when pyrolysis take place [20,22].…”

Direct carbon fuel cell (DCFC) with higher power efficiency and lesser emissions is being viewed as a potential clean energy source. The application of renewable biochar as fuel for DCFC is found to be feasible to replace coal or carbon black for power generation. Black liquor from the paper production might be a suitable fuel source for DCFC due to its high lignin or carbon content. In this study, the feasibility of using compound extracted from black liquor as fuel source for DCFC was investigated in the aspect of physico-chemical and electrochemical properties. Suitable pyrolysis temperature in producing biochar from black liquor compound was first investigated. Results have shown that fixed carbon and ash content increased slightly with increasing pyrolysis temperature. The ash content is made up of majority of silica as depicted in FESEM-EDX results. Oxygen containing functional group was decomposed under high pyrolysis temperature of 700°C and 800°C. Besides, biochar obtained at 500°C of pyrolysis temperature has given the highest power density of 1.22 mW cm-2 whereas 1.44 mW cm-2 was obtained from coal which was used as the control. Future work on ash removal from the black liquor prior to pyrolysis might improve the potential of black liquor derived compound as a fuel source for DCFC.

“…Although biochar can be utilized as an adsorbent for wastewater treatment (Della et al, 2020), it is also an effective material in carbon sequestration and soil enrichment to improve the nutrients and water holding capacity of the soil (Selvarajoo et al, 2022). Overall, biochar possesses great potential as a renewable fuel alternative in energy production due to its high carbon and energy composition (Chong et al, 2019;Postawa et al, 2022).…”

“…In view of the extremely complex nature of the co-pyrolysis process, use of ANN and machine learning has been recommended for process optimization. Selvarajoo et al 57 have prepared biochar from citrus peel biomass using slow pyrolysis in the temperature range of 300 to 700 °C. They have observed that a higher yield of biochar is obtained at the lower pyrolysis temperature.…”

The finite nature, regional availability, and environmental problems associated with the use of fossil fuels have forced all countries of the world to look for renewable eco-friendly alternatives. Agricultural waste biomasses, generated through the cultivation of cereal and noncereal crops, are being considered renewable and viable alternatives to fossil fuels. In view of this, there has been a global spurt in research efforts for using abundantly available agricultural wastes as feedstocks for obtaining energy and value-added products through biochemical and thermal conversion routes. In the present work, the thermochemical characteristics and thermal degradation behavior of sugarcane leaves (SCL) and tops were studied. The batch pyrolysis was carried out in a fixed-bed tubular reactor to obtain biochar, bio-oil, and pyrolytic gas. Effects of bed height (4–16 cm), particle size (0.180–0.710 mm), heating rate (15–30 °C/min), and temperature (350–650 °C) were investigated. The maximum yields of bio-oil (44.7%), biogas (36.67%), and biochar (36.82%) were obtained at 550, 650, and 350 °C, respectively, for a 16 cm deep bed of particles of size 0.18–0.30 mm at the heating rate of 25 °C/min. The composition of bio-oil was analyzed using Fourier transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance ( 1 H NMR), and gas chromatography–mass spectrometry (GC–MS) techniques. Several aliphatic, aromatic, phenolic, ketonic, and other acidic compounds were found in the bio-oil. The biochar had a highly porous structure and several micronutrients, making it useful as a soil conditioner. In the middle temperature ranges, biogas had more methane and CO and less hydrogen, but at higher temperatures, hydrogen was predominant.
