QUESADA-GONZALEZ, Omaida et al. Kinetic study of orange peel combustion. Rev Cub Quim [online]. 2018, vol.30, n.1, pp. 27-44. ISSN 2224-5421.

The kinetic study of orange peel combustion has been conducted using experimental results of the termogravimetric analysis. This study made use of several equations: Coats (integral), Sharp y Achar (differentials) and Isoconversion (free kinetic). By means of the combination of these equations, the kinetic results for natural materials are more reliable. The final kinetic models are D4-D2 for dehydration, decompositions of hemicellulose and cellulose by D4, and F1 for lignin. The rank of energy activation ranges 80-90 kJ/mol (kinetic free) and 48-162 kJ/mol (model fitting method) because simultaneous reactions occur.

Keywords : orange peel; kinetics; combustion.
