Parametric Study of the Two-Stage Pyrolysis Process for Activated Carbon Preparation from Pithecellobium Jiringa

Activated carbon is a type of carbon processed to have small and low volume pores that improve the surface area available for chemical reactions. Currently, the cost of activated carbon is inefficient and it is difficult to obtain activated carbon. Pithecellobium jiringa (Jering) is an organic material that is potentially used as raw material for activated carbon. However, the use of Jering waste as activated carbon is new; the previous researchers never obtained data on the correlation between the parameters. The objective of the project is to design a two-stage pyrolysis process to evaluate the effect of hydroxide (KOH) on the conductivity of activated carbon and to evaluate the effect of ambient temperature on activated carbon. There are two stages in the pyrolysis process; to remove moisture and activate the carbon with KOH. The performance of the heating rate for this space is 5 °C per minute at 30 °C per minute. The highest temperature for this heating coil is 235 °C. The amounts, and molar volumes of KOH can affect the performance of the voltage.
