The single-step activation in presence of purified CO2 was adopted in this research study.
Approximately 20 g of dried palm kernel shell was weighed into an alumina crucible boat and
was positioned inside the Carbolite® CTF 12/100/900 tube furnace. The experimental setup
consisted of 100 mm diameter and 900 mm long tubular furnace that was mounted horizontally.
Inside the furnace, an impervious aluminous porcelain tube was placed. Heating rate, dwelling
time, and activation temperature were controlled by using a digital Eurotherm® controller, and
was aided by a thermocouple. Prior to activation, N2 was flown at flow rate of 150 cm3
/min for
about 30 min in order to remove any presence of air. After that, CO2 activation was carried out
by ramping the temperature from an ambient temperature to 850oC at heating rate of 5 oC/min,
and hold for 1 hr. CO2 flow rate was retained at 450 cm3
/min. The cooling step was performed
in presence of N2 flow, prior to the sample collection for subsequent characterization and CO2adsorption. Yield (in dry weight basis) of the synthesized activated carbon was calculated by
dividing the final mass of activated carbon to the initial mass of raw precursors loaded into the
alumina crucible boat.
