“…Then, the entire samples undergo the pre-drying treatment in order to obtain moisture free samples. Wet feedstock will cause low efficiency of heating process during pyrolysis, which is related to the volatization of moisture [10]. So, predrying treatment will give off non-flammable component such as carbon dioxide and water.…”

Production of biochar from slow pyrolysis of biomass is a promising carbon negative procedure since it removes the net carbon dioxide in the atmosphere and produce recalcitrant carbon suitable for sequestration in soil. Biochar production can vary significantly with the pyrolysis parameter. This study investigated the impact of temperature and heating rate on the yield and properties of biochar derived from cassava plantations residues which are cassava stem (CS) and cassava rhizome (CR). The pyrolysis temperatures ranged from 400 C to 600 C while the heating rate parameter was varied from 5 C/min to 25 C/min. The experiment was conducted using the lab scale slow pyrolysis system. The increment of temperature and heating rate of slow pyrolysis for both cassava wastes had raised the fixed carbon content of the biochar but decreased the biochar yield. More biochar was produced at lower temperature and lower heating rate. Temperature gave more influence on the biochar yield as compared to the heating rate parameter. The highest biochar yield of more than 35 mf wt. % can be obtained from both CS and CR at 400 C and heating rate of 5 C/min. From the proximate analysis, the results showed that cassava wastes contain high percentage of volatile matter which is more than 80 mf wt. %. Meanwhile, the biochar produced from cassava wastes contain high percentage of fixed carbon which is about 5 8 times higher than their raw samples. This suggested that, it is a good step to convert CS and CR into high carbon biochar via slow pyrolysis process that can substantially yield more biochar, up to 37 mf wt. % in this study. Since the fixed carbon content for both CS and CR biochar produced in any studied parameter were found to be more than 75 mf wt. %, it is suggested that biochar from cassava wastes is suitable for carbon sequestration.

“…Also the moisture content, ash content and pHpzc of the PTPS adsorbent are similar to those reported by Pandey et al, (2015) for Kush grass and bamboo leaves adsorbents. The PTPS adsorbent has a high volatile matter content which is characteristics of the organic nature of the lignocellulosic biomass which contains cellulose, lignin and hemicellulose (Khor et al, 2009). Odetoye et al, (2014) in their study on the thermochemical characterisation of Parinari polyandra Benth fruit shell reported a 78% volatile matter content for this biomass thus indicating its high organic matter content compared to that of the PTPS residue adsorbent.…”

“…The drastic yield reduction at the initial stage of thermal treatment (<500 C) followed by a slow decrease thereaer has been observed for lignocellulosic biomass feedstocks. [37][38][39][40][41] These trends of reduction in biochar yield reect the devolatilization of organic polymers of the feedstock and the slow carbonization of the solid residue. Quality properties such as xed carbon and volatile matter contents increase and decrease with temperature, respectively.…”
