“…These represent the crystallographic planes 200, 110 and 004, respectively, according to the native cellulose structure [20][21][22][23]. These characteristic peaks in the diffractogram are comparable to the Napier grass peaks identified by Reddy et al [6].…”

Study on Napier grass leaf (NGL), stem (NGS) and leaf and stem (NGT) was carried out. Proximate, ultimate and structural analyses were evaluated. Functional groups and crystalline components in the biomass were examined. Pyrolysis study was conducted in a thermogravimetric analyzer under nitrogen atmosphere of 20 mL/min at constant heating rate of 10 K/min. The results reveal that Napier grass biomass has high volatile matter, higher heating value, high carbon content and lower ash, nitrogen and sulfur contents. Structural analysis shows that the biomass has considerable cellulose and lignin contents which are good candidates for good quality bio-oil production. From the pyrolysis study, degradation of extractives, hemicellulose, cellulose and lignin occurred at temperature around 478, 543, 600 and above 600 K, respectively. Kinetics of the process was evaluated using reaction order model. New equations that described the process were developed using the kinetic parameters and data compared with experimental data. The results of the models fit well to OPEN ACCESSEnergies 2015, 8 3404 the experimental data. The proposed models may be a reliable means for describing thermal decomposition of lignocellulosic biomass under nitrogen atmosphere at constant heating rate.

“…Trake koje se javljaju na 1592, 1504 i 1456 cm -1 se javljaju usled pojave C=C veze u aromatičnom prstenu lignina [27][28][29]. Pikovi na 1421 i 1372 cm -1 mogu se pripisati -C-H asimetričnoj i simetričnoj valencionoj vibraciji, resepektivno [30]. Pik na 1030 cm -1 se može povezati sa postojanjem valencione vibracije -C-O iz alkohola ili karbonskih kiselina [27].…”

Influence of temperature on the production and size distribution of fine particles released from beech wood samples

et al. 2018

Abstract. Fine particles generated from laboratory biomass combustion are discussed in this study. The approach combines the thermogravimetric analysis during thermal decomposition of beech wood sample with detailed monitoring of the size distribution of fine particles produced. Thermogravimetric analysis (TGA) allows monitoring the exact temperature influence of a small fuel sample (wood) according to the desired schedule. The cool aerosol stream leaving TGA enters a Scanning Mobility Particle Sizer (SMPS) where the particle size fractions are separated. The monodisperse aerosol is counted by the condensation particle counter (CPC). The parametrical study was carried out to assess the influence of composition, size and surface of the wood sample on the production and size distribution of ultrafine particles
