Abstract:

Coconut shell (Cocus Nusifera), an agricultural waste converted into activated carbon in integrated carbonization cum activation unit at steam flow rate of 0.75 kg/h and temperature of around 550 ºC. The steam activation was conducted for 1 h and 2 h residence times. The waste heat of carbonization process was utilized for steam generation and activation process. The mass conversion efficiency of carbonization was found to be 16.49% and 12.60% and the yield of steam activation process was 88% and 80% for 1 h and 2 h residence time respectively. Adsorption properties showed that better quality of 2 h residence activated carbon with iodine number as 546 mg/g and methylene number of 318 mg/g and iodine number as 485 mg/g and methylene number of 288 mg/g for 1 h residence time activated carbon.
