A comparative analysis of kinetic parameters from TGDTA of Jatropha curcas oil, biodiesel, petroleum diesel and B50 using different methods

► The TGA thermograms presented for different fuels viz. JCO, JCME (KOH), JCME (NaOH), petroleum diesel and B50 blends. ► Calculations of the different parameters applicable for kinetic study purposes using three different methods. ► The refined JCO has highest value of activation energy 49.97 kJ/mol while petroleum diesel has the lowest (9.11 kJ/mol).
