2.2.3. Heating value
The heating value of EFB was determined by burning a weighed
sample in an adiabatic oxygen-bomb calorimeter (model Parr
1341, USA) following the ASTM D240 method. EFB (0.5 g) was
placed in a metal cup connected with a fuse wire; the cup was
placed inside the bomb calorimeter and charged with oxygen to
approximately 200 psi. The heat of combustion was computed
from the temperature observations before, during, and after
