Abstract:
The physical effect of activated carbon electrodes prepared from the shell biomass of
rubber seeds has been successfully analyzed. Carbon electrodes from rubber seed
shells were prepared through pre-carbonized process, chemical activation with KOH
activator 0,5 M, the carbonized process at a temperature of 600°C at a nitrogen gas
environment and a physical activation process with temperature variations of 650°C,
750°C and 850°C at carbon dioxide gas environment. The average percentage of
mass reduction is 24.47%. The density values of each carbon electrode for physical
activation temperatures of 650 C, 750 C and 850 C are 10.98%, 32.63% and 29.05%.
The largest percentage density value obtain in this research is 32.63%. Moreover, the
physical activation temperature affects the carbon electrode density of the rubber seed
shell with the best physical activation temperature of 750℃.
