In this paper, an attempt has been made to produce activated carbon from tamarind wood, which is a forest waste, rich in lignocellulosic material. The characterisation of the activated carbon is done based on carbonisation time, temperature, pore volume and Brunauer, Emmett and Teller (BET) surface area under various operating conditions. The Scanning Electron Microscopy (SEM) analysis is also done to study the morphological changes of the chemically activated carbon. The best condition for the production of the high BET surface area of 1240 m²/g activated carbon from tamarind wood by chemical activation is found to be 100% chemical ratio (activated agent/precursor) at a carbonisation time of 60 min and carbonisation temperature of 500°C.
