In this study, Activated
carbon from pistachio shell has been successfully
produced through carbonization
and CO2 activation.
The pistachio shell has been carbonized at 300,400,500,600,700,800,900,1000oC
temperature, 100 and 500ml/min inert nitrogen atmosphere. Char, liquid and
gases yields have been investigated during carbonization process. In the carbonization, generally
the solid yield decreases as the temperature increases, while the gas
efficiency increases. The increase in liquid yield was lower than the gas
yield. Carbonized samples were subjected to physical activation with carbon
dioxide at a flow rate of 100 ml / min at 800oC and 900oC.
As a result of carbon dioxide activation, BET surface area values were obtained
in the range of 16, 66-857, 13 m2 / g. The highest surface area was
obtained as 857,13 m2 / g at 600oC carbonization temperature, 100 ml
/ min nitrogen flow rate and 800oC activation temperature 100 ml /
min carbon dioxide flow rate. The mean pore diameter values of the activated
carbon samples were measured in the range of 2.07-4.06 nm. The average pore
size distribution of some of the samples is in a relatively narrow range and is
mostly of molecular sieve size in nano pore size. According to XRD results, all
samples were found to be amorphous
