A. Effect of Pyrolysis Temperature
The shell size 2.18 mm and residue were selected to pyrolysis process under N2 flow on 100 ml/min by
varying the temperature in range of 300-450 C. The results were shown in Fig.3
Fig.3 shows the bio oil yield from shell increased with pyrolysis temperature from 300 to 450 C, by the
way bio oil yield from residue seem that slightly decreased from 400 to 450 C. It seemed that the bio oil
from shell was inversely proportional with from residue. Especially, in the range of residue temperature
300-350 C, the thermal cracking of volatile effect to be higher forward reaction rate and higher the bio oil
yield. Although pyrolysis is endothermic reaction, at the temperature higher than 400 Cbio oil yield seem
to be decreasing since the continuously generation of secondary thermal cracking [6]. At the secondary
thermal cracking condition, some solid as charcoal were continuously pyrolyzed to be un-condensable gas
that affected the lower amount of bio oil but higher amount of gas from the process. The highest bio oil
yield from shell was showed as 36.69 at the condition of temperature of 450 C, while the residue supplied
as 31.78 at 400 C.
