(referred to
25, 50, 100wt. % loading). The sample was then
dried in an oven at 103°C for how 8 hours. The
Pyrolysis experiments were carried out at 600 and
800°C with a residence time of 1h in a nitrogen
atmosphere. The reactor was purged before the
experiments by a nitrogen gas flow of 30 mL min
-1
for 30 min to remove the air inside, and the purging
nitrogen was fixed at 30 mL min-1and continued to
the end of the pyrolysis, which includes the cooling
down of the reactor to the room temperature. The
pyrolysis reactor was a fixed bed design of stainless
steel with 6 cm diameter and 2 cm height. The
impregnated sample was placed into the reactor
