Abstract:
S. quadricuda’s bioenergy potential was studied via pyrolysis by the use of
thermodynamic and kinetic analysis. Mean energies of activation which were calculated
using isoconversional techniques were 152.370(±20.93O) and 153.000 (±21.23O) and
174.980 (±22.38O) Kj/mol, utilizing Friedman& Vyazovkin’s advanced techniques and
OFW technique. From joined analysis it was known that A1/4 reaction model of AvramiErofeev was most likely a single step reaction mechanism. But according to profile of
activation energy there was complicated degradation in active pyrolysis zone, in this zone
there were independent two parallel reactions. Fot the conversion at low temperature mean
energy of activation was 77.950 (±3.12o) kJ/mol with 4.860E4 (±2.240E4) 1/s preexponential factor and n = 1.510 (±0.100), And high temperature 73.26 0(±17.93O)
kJ/mol mean activation energy is recorded. Whereas pre-exponential factor was 1.320E03
(±2.610E3) s-1, and n=1.210 Feasibleness of conversion was indicated via
thermodynamic analysis involving entropy, Gibbs free energy and enthalpy.
