“…However, the concentration of lignin stayed relatively similar. Although the concentration of citric acid was only half of what was proposed in the study of Rodríguez-Machín et al [51], the hemicellulose still underwent partial hydrolysis. These results indicate a very high sensitivity of hemicelluloses to acid treatments, even when weak organic acids are used.…”

“…To adjust the mineral matter content and to mitigate the aforementioned problems, acid leaching can be applied before pyrolysis. However, this leaching can also cause a degradation of the macromolecular components of the biomass [51] and thus influencing the pore development and complicating the tailoring of the PSD of the pyrochar.…”

Char obtained from biomass pyrolysis is an eco-friendly porous carbon, which has potential use as a material for electrodes in supercapacitors. For that application, a high microporous specific surface area (SSA) is desired, as it relates to the accessible surface for an applied electrolyte. Currently, the incomplete understanding of the relation between porosity development and production parameters hinders the production of tailor-made, bio-based pyrochars for use as electrodes. Additionally, there is a problem with the low reliability in assessing textual properties for bio-based pyrochars by gas adsorption. To address the aforementioned problems, beech wood cylinders of two different lengths, with and without pre-treatment with citric acid were pyrolysed at temperatures of 300-900°C and analysed by gas adsorption. The pyrolyzed chars were characterised with adsorption with N 2 and CO 2 to assess the influence of production parameters on the textual properties. The new approach in processing the gas adsorption data used in this study demonstrated the required consistency in assessing the micro-and mesoporosity. The SSA of the chars rose monotonically in the investigated range of pyrolysis temperatures. The pre-treatment with citric acid led to an enhanced SSA, and the length of the cylinders correlated with a reduced SSA. With pyrolysis at 900°C, the micro-SSAs of samples with 10 mm increased by on average 717 ± 32 m 2 /g. The trends among the investigated parameters and the textual properties were rationalized and provide a sound basis for further studies of tailor-made bio-based pyrochars as electrode materials in supercapacitors.

“…The effect of citric acid on cane bagasse was studied [61], where changes to the FTIR spectra could be attributed to the modification of the xylan fraction and to the substitution of C]O by OH groups. These mild structural changes, caused by hydrolysis, led to the disappearance of the hemicellulose decomposition peak in the DTG curve.…”

Relevant literature which deals with the presence of metals during the catalytic pyrolysis of biomass is reviewed. Only those conditions where the metal was in intimate contact with the biomass components are included. Cellulose, hemicellulose and lignin all fuse during the early stages of pyrolytic heating and the dehydration and decomposition processes begin during this transition. Hemicelluloses such as xylan are more labile and difficult to isolate, whereas both cellulose and lignin produce mostly bio-oils when demineralised and flash pyrolysed. The dominant primary products from 'pure' cellulose are anhydrosugars as well as smaller oxygenates. Lignin gives aromatics based on the syringol and guiacol molecules. The alkali and alkaline earth metals are found to curtail the yield of bio-oil and modify product distribution, even in the low concentrations naturally found in biomass. All other metals act to catalyse cross-linking reactions, with the nickel and zinc most studied. The electropositivity of the metal tends to correlate with the extent of catalytic activity. The presence of metals causes little change to the production of gases, but more char is formed at the expense of liquids. If the aim of pyrolysis is bio-oil for fuel, prewashing of biomass to remove metals is beneficial.

“…Sugarcane harvest residue can provide nutrients for plants but cannot be absorbed directly by plants (Fortes et al, 2013). Sugarcane litter must go through a decomposition process before absorbed by plants (Fortes et al, 2012;Dietrich et al, 2017;Rodríguez-Machín et al, 2018). Based on the research conducted by Quirk and Zwemer (2007) in their trial at the McLeods Creek site, the rate of decomposition of organic matter can be significantly accelerated by the application of urea fertilizer sprayed onto the surface of the material in small quantities (1.5-3 kg ha -1 ).…”

Sugarcane harvest results in plant residues, consisting of leaves, stems and roots nearly 20 ton ha-1. The plantation of PTPN VII in Cinta Manis District applied urea with a dosage of 5 kg ha-1 but the result was not effective. There is a potential to try a higher dosage of urea to enhance trash decomposition. This research aims to evaluate urea application on biomass decomposition. This research was conducted on the Plot 07 Rayon 3 of PTPN VII, District of Cinta Manis at Ketiau, Lubuk Keliat of Ogan Ilir, South Sumatra, using Split Plot design. Main plot is trash sampling time and subplot is urea dosage with three replicates. ANCOVA was used for soil data. The rate of decomposition of the litter was calculated by the change in the initial condition of research with each week on observation resulting in decomposition rate graphs. Urea application at 10 kg ha-1 reduced C/N of the litter ratio to almost 21:1 and was followed by the highest total nitrogen increase to 0.18%, while the highest organic carbon decline for urea treatment of 6 kg ha-1 amounted to 13.78%. In conclusion, higher rate of urea application is still required to enhance sugarcane litter decomposition.
