      This research aims to design pyrolysis reactor, develop pyrolysis operating procedure, and to investigate the effect of pyrolysis temperature to liquid product quality. The pyrolysis experiments will be performed in batch reactor equipped from carbon steel with 20 cm inside diameter and 40 cm height. The experimental conditions are as follows: temperature range 250-400 degrees C, and reaction time 0-30 min. The effect of inert (N2) flow rate to liquid product quality will also be observed. From all variables studied, it seemed that temperature had the highest effect. Chemical reaction rate constant was affected by temperature in accordance with Arrhenius equation. The activation energy of k was 12145,4 cal./mole, respectively. This value was not so far from the extreme values (104 cal/mole) presented by Westerterp et al. These facts ascertained that the chemical reaction step controlled the overall rate of reaction. The highest volatile matter conversion in this research was 46,5%, and this was obtained at process conditions of 30 minutes and temperature of 360oC. The pyrolytic oil yield increase with the increase of the temperature and its composition becomes more variative and few contents of carboxylic acids and aromatics compound.
