Preparation and Characterization of Activated Carbon from Waste of Jengkol Shell (Pithecellobium jiringa)

. Agustina, Ananda Putra

Abstract


The purpose of this study was the preparation and characterization of activated carbon from jengkol shell waste. Activated carbon was made through the process of dehydration, carbonization, and activation. The method used for making carbon from jengkol shell was pyrolysis with variations in the pyrolysis temperature of 300˚C, 330˚C, and 350˚C. The activation stage uses a chemical activation method that was using a variety of activated reagents which is HCl, KOH and ZnCl2 and variations of concentration of activated reagents which is 2N, 4N, and 6N. The activated carbon that was obtained will be tested with the following parameters: water content, ash content, vapor content and bounded carbon  content. In this study, the standar used to determine the characteristics of activated carbon was the Indonesian National Standard (SNI 06-3730-1995). The results showed that the carbonization temperature of 300˚C and the activated reagent of HCl 4N showed the most optimal result of  activated carbon where the water content was 1,72%, the ash content was 0,39%, the vapor content was 10,78%, and the bounded carbon content was 88,83 %. Based on these results it can be concluded that the jengkol shell waste can be used as an activated carbon that meet the Indonesian National Standards (SNI 06-37301995).
