摘要

Pyrolysis of metal soap is an attractive route for producing renewable energy and chemicals. Nevertheless, the complexity of the pyrolysis kinetic in a non-isothermal system still becomes a challenge. In this study, the thermal behavior and pyrolysis kinetics of metal soap from nyamplung seed oil (OA-Zn) were studied using TGA at heating rates of 10, 20, and 40 °C min−1 at 400 °C. The kinetic modeling employed the volatile state advanced isoconversional method (VS-AIM). According to the results, the decomposition starts at 190–200 °C, and the behavior displays one peak in the DTG curve at 380–400 °C. The results of kinetic interpretation show that the average value of activation energy is 231.09 kJ.mol−1. Moreover, a linear correlation is observed from the compensation effect aspect. Lastly, the BCO yield in 10.04%-wt which consists of several fractions such as light bio-hydrocarbons, aromatic compounds, resins, and asphalts. Thus, the BCO can be further processed as biofuels and/or chemical building blocks.
