| Summary: | Dabai (Canarium odontophyllum) nutshells have considerable potential to
be used as a viable precursor for biomass-based activated carbon. The
material was carbonized at a temperature of 700 °C for 2 h, at a heating
rate of 10 °C/min under nitrogen gas flow. The char was analyzed the
following ways: percentage of yield, percentage of ash content, Fourier
transform infrared spectroscopy, scanning electron microscopy with
energy dispersive x-ray analysis, and Brunauer, Emmett, and Teller
surface area. The char had a maximum Brunauer, Emmett, and Teller
surface area of 428 m2
/g and the nitrogen adsorption-desorption isotherm
of the char that was similar to a Type I adsorption isotherm, based on
IUPAC classifications. The char also had a high carbon content (up to
93.6%) and a low ash content (3.67%). Therefore, dabai nutshells were
found to be a suitable lignocellulosic precursor for the synthesis of
activated carbon. |
