Pyrolytic Degradation Behavior of Biomass Seeds: Cherry And Peach Seed

Abstract

Pyrolytic degradation behavior of peach and sour cherry seed were investigated by thermal analysis techniques such as thermogravimetric (TG) and derivative thermogravimetric (DTG). Pyrolysis study of peach and sour cherry seed, which are the sources of plant biomass, were carried out under air flowrate 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). Although the FWO method gives higher values, it was observed that all activation energy values calculated by both methods are compatible with each other. In addition, as the amount of volatile matter increases, the decomposition becomes difficult due to the increase in mass transfer resistance and pressure, so it was determined that the activation energy of the peach seed is higher than the sour cherry seed.
