OPTIMASI SUHU DAN LAMA AKTIVASI DENGAN ASAM PHOSFAT DALAM PRODUKSI ARANG AKTIF TEMPURUNG KEMIRI
ABSTRACT: Candlenut shell as a
lignocelullose raw material is a potential by-product for produce activated
charcoal. It’s quality are affected by raw material and activated process i.e.
temperature, activation time and activating agent. This paper intends to study the properties of
activated charcoal made from candlenut shell. Candlenut shell was carbonization
at 500 °C for 5 hour. Then activated using phosphoric acid in three different
temperatures: 600 °C, 700 °C and 800 °C, in the duration time of 90, 120 and
150 minutes. The result shows that
candlenut shell activated charcoal more influence of temperature than activation
time. Overall, the activated charcoal met the Indonesian Standard requirement
for commercialised activated charcoal with optimation activation at 800 °C for 120 minute.
Keywords: Candlenut shell,
