Abstract
- The pyrolytic kinetics of Jerusalem artichoke stalk, cornstalk, and sawdust (the latter two served as control) were investigated using a thermogravimetric analysis method under an inert atmosphere at heating rates of 5, 10, 20, and 30°C/min from 50 to 800°C. For Jerusalem artichoke stalk, starting with the dehydration step between 30 and 150°C, the main thermal decomposition process showed two distinct degradation zones, corresponding to the devolatilization step between 200 and 400°C and the combustion step between 400 and 600°C. Kinetic expressions for the degradation rate in devolatilization and combustion steps have been obtained for Jerusalem artichoke stalk with Popescu, Flynn-Wall-Ozawa, and Kissinger-Akahira-Sunose methods. The results showed that the model agreed well with the experimental data and provided useful information for the design of a pyrolytic processing system using Jerusalem artichoke stalk as feedstock to produce bio-fuel.
