Bio-fuel oil characteristic of rice bran wax pyrolysis

The pyrolysis characteristic of rice bran wax (RBW) and its bio-fuel oil were analyzed. TG, Py-GC-MS, TG-MS, FTIR, 1H NMR and 13C NMR were all carried out to analysis RBW pyrolysis characteristic and bio-fuel oil characteristic. TG results showed that RBW pyrolysis temperature was mainly in the temperature range of 350 °C-450 °C. The mean activation energy values calculated from KAS method and FWO method was 106.15 kJ/mol and 115.72 kJ/mol, respectively. The TG-MS results showed that main gas products were alkane and olefins. The Py-GC-MS also found the mainly components of pyrolysis products were alkane and alkene. The 1H NMR, 13C NMR and FTIR experiments were also carried out to confirm the component of bio-fuel oil. The results found that the main components of pyrolysis products were alkane and alkene. The bio-fuel oil properties were also analyzed. The acid value was very low. It was about 10 mg(KOH)/g. And the coke was found. The yield was about 8%. According to above results, it was confirmed that RBW maybe was a good bio-resource to obtain long carbon chain bio-fuel oil.
