Pyrolytic Degradation Behavior of Biomass Seeds: Cherry And Peach Seed

Abstract

Pyrolytic degradation behavior of peach and cherry seed were investigated by thermal analysis techniques such as thermogravimetric (TG) and derivative thermogravimetric (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 (KAS) and Flyn–Wall–Ozawa (FWO). The average activation energies (Ea) and pre-exponential factor (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.
