Abstract :Pyrolytic degradation behavior of peach and cherry seed were investigated by thermal analysis techniques such as thermogravimetric insert ignore into journalissuearticles values(TG); and derivative thermogravimetric insert ignore into journalissuearticles values(DTG);. Pyrolysis study of peach and cherry seed, which are the sources of plant biomass, are carried out under air flow rate of 10 mL.min-1 and heating rates of 2.5-5-10 and 20 K min-1 in the temperature range of 298-1173 K by means of thermal analysis techniques. The activation energy and pre-exponential factor were determined with different methods as Kissinger–Akahira–Sunose insert ignore into journalissuearticles values(KAS); and Flyn–Wall–Ozawa insert ignore into journalissuearticles values(FWO);. The average activation energies insert ignore into journalissuearticles values(Ea); and pre-exponential factor insert ignore into journalissuearticles values(A); obtained from both models for cherry and peach seed were found as: Ea=125.77 kJ mol-1 and A=13.03 min-1 for KAS; Ea=135.59 kJ mol-1 and A= 27.77 min-1 for FWO and Ea=204.93 kJ mol-1 and A=34.12 min-1 for KAS; Ea=213.47 kJ mol-1 and A= 44.34 min-1 for FWO, respectively.
