Abstract
The aim of this research is to produce activated carbon from Indonesian coal with rotary
autoclave and the rotation of rotary autoclave is ± 6 rpm. In this research, after fill in the raw
material to autoclave, activated carbon were produced with following processes: carbonization;
coal were pyrolysed at temperature 300oC for 6 hour with flowed of oxygen and physical
activation; After carbonization process coal were pyrolysed at temperature 950oC for 6 hour
and CO2 were flowed into autoclave as activating agent up to 300 ml/minute. Iodine Number is
a quality parameter of activated carbon was done at laboratory. The result of this research is the
iodine number of activated carbon with vertical autoclave is higher than rotary autoclave. The
maximum iodine number with vertical autoclave is 589.1 mg/g and with rotary autoclave is
247.63 mg/g.
