Abstract

---

In the author’s previous study, low molecular weight - methyl esters (LMW-ME) with carbon - carbon double bond at the end of alkyl chain [CnH2n-2O2] with n=4-9 are generated by a biodiesel utilizing diesel engine. However, the detail chemical kinetic of thermal decomposition is not clearly comprehended. This experiment study aims at better understanding a detail kinetic for thermal decomposition of LMW-ME, performed in an isothermal flow quartz tube reactor at atmospheric pressure. LMW-ME standards were constantly introduced to thermal decomposition system using pump and mass flow controller. The reactant input was fixed at each LMW-ME compound. The tubular reactor was ranged from 773 to 973 K, at residence time between 0.56 and 5.14 min. The emission gas was absorbed by Cabopack B 100 mesh, eluted by CS2 solvent and analyzed by GCMS. Assuming the decomposition reaction is first order, the activation energy of C4 to C9 was 68.51, 52.03, 50.66, 42.50, 47.83 and 32.01kJ/mole, respectively. The rate constant order of LMW-ME is C4
