Production of activated carbon from ligin: Optimization using response surface methodology

Activated carbon (AC) were prepared from lignin by chemical activation with sodium hydroxide (NaOH). The influence of activation temperature, activation time and impregnation ration on the BET surface areas were investigated. Based on the central composite design (CCD) and response surface methodology(RSM), the optimized technological parameters were as follows: temperature 751 °C, time 57min and impregnation ration 2.06, BET surface areas was up to 1437.20 m2/g.The adequacy of the model equation for predicting the optimum response values was verified effectively by the validation.
