“…These bands or peaks found on dried raw eucalyptus wood chips have disappeared after steam activation at temperatures of 500–700 °C. This indicates the thermal degradation of surface functional groups during the carbonization stage, which were decomposed to CO and CO 2 gasses 10 . The C–H bond and O–H groups were removed from all of the activated carbon materials (Fig.…”

“…On the other hand, the fixed carbon content has increased with increasing steam activation temperature. These results are due to the thermal degradation of volatile matter and decomposition of carbon in the form of CO, CO 2 , and CH 4 10 . Partial oxidation with water vapor, as shown in reactions ( 1 – 4 ), has taken place to a higher degree at higher activation temperatures 11 .…”

The production of activated carbon from eucalyptus wood chips by steam activation in a 2000 kg batch intermittent rotary kiln with continuous carbonization–steam activation process conducted at 500 °C to 700 °C was studied. The activated carbon products were characterized by FTIR, SEM–EDS, Raman spectroscopy, and BET analysis. Percent yields, iodine number, and methylene blue number of the produced activated carbon materials were measured as well. It was shown that the percent yields of the activated carbon materials made in the temperature range from 500 to 700 °C are 21.63 ± 1.52%–31.79 ± 0.70% with capacities of 518–737 mg I2/g and 70.11–96.93 mg methylene blue/g. The BET surface area and micropore volume of the activated carbons are 426.8125–870.4732 m2/g and 0.102390–0.215473 cm3/g, respectively. The steam used in the process could create various oxygen containing surface functional groups such as –CO and –COC groups. In addition, it could also increase the amorphous nature of the activated carbon product. These properties of the activated carbon products are increased with increasing steam activation temperature from 500 to 700 °C. As a result, the activated carbon materials produced at activation temperatures of 600 °C and 700 °C exhibit higher adsorption.

“…2a) to 1504.88 cm − 1 in the activated carbon materials (Fig. 2b-d), may be attributed to reduction of sidechain aromatic ring-oxygen-containing surface functional groups and high degree of graphitization after carbonization at high temperature 9 . On the other hand, the peak of C = O groups found at 1720 cm − 1 in raw eucalyptus wood chips has transformed to a weak peak at about 1700 cm − 1 after activation.…”
