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 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. © 2015 by the authors. date: 2015 publisher: MDPI AG official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84930811247&doi=10.3390%2fen8053403&partnerID=40&md5=31c950fb4423f27ac99e29acb3f91591 id_number: 10.3390/en8053403 full_text_status: none publication: Energies volume: 8 number: 5 pagerange: 3403-3417 refereed: TRUE issn: 19961073 citation: Mohammed, I.Y. and Abakr, Y.A. and Kazi, F.K. and Yusup, S. and Alshareef, I. and Chin, S.A.
