Determination Of Pyrolysis Kinetics Of Pistachio Shell And Cranberry Seed
Öz
Pyrolytic degradation behavior of pistachio shell and cranberry seed were investigated by means of thermal analysis techniques such as thermogravimetric (TG) and derivative thermogravimetric (DTG). Pyrolysis study of pistachio shell and cranberry seed, which are the sources of plant biomass, are carried out at four different heating rates (2.5, 5, 10 and 20 K min-1) in the temperature range of 300-1173 K in a TGA equipment. The activation energy and pre-exponential factor were determined using 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 the pyrolytic degradation behavior of pistachio shell and cranberry seed were found as: Ea=146.5 kJ mol-1 and A=17.99 min−1 for KAS; Ea=159.3 kJ mol-1 and A= 34.15 min−1 for FWO and Ea=191.1 kJ mol-1
and A=25.93 min−1 for KAS; Ea=210.7 kJ mol-1 and A= 42.63 min−1 for FWO, respectively.
