Pyrolysis of ficus nitida wood: Determination of kinetic and thermodynamic parameters

In the present work, kinetic and thermodynamic analysis of ficus wood was carried out using thermogravimetric (TGA). Thermal degradation has been evaluated under dynamic conditions from 373 K to 1173 at heating rates 5, 10, 20, 50 K.min?1. The performed isoconversional methods (Friedman (FR), Flynn-Wall-Ozawa (FWO) Vyazovkin (VYA)) integral master-plots method estimate triplets. data were used calculate parameters (?G, ?H ?S) compensation effects. conversion range 0.05 ? x 0.9 shows clearly that pyrolysis could represent a triple-step reaction, which corresponds hemicellulose, cellulose, lignin, respectively. From plots having average activation energy values 171.4–180.3 kJ.mol?1, 206.48–214.42 kJ.mol?1 237.85–248.23 for experimental focus had overlapped D4, D2, F3 in 5–35%, 35–75%, 75–90%, All ?G maintain positive constant, whereas value ?S is negative 5–35%. difference between E-values three pseudo-components about ?5 kJ.mol?1. will be beneficial assimilating thermal decomposition its use bioenergy.
