Optimization of Operating Parameters Using Response Surface Methodology for Preparation of Sugarcane Bagasse-Derived Activated Carbon Via Chemical Activation
Keywords:
Activated carbon, Zinc Chloride, Box-behnkenAbstract
The sugarcane bagasse-derived activated carbon was synthesized via impregnation-carbonization method. The different weight ratio of ZnCl2 (1:1 to 1:3), carbonization temperature and time of 400-600°C and 60 to 120 min respectively were designed using Box-Behnken Design Minitab. The porous, textural, structural and thermal stability of produced activated carbon will be characterized by N2 adsorption/desorption, SEM, FTIR respectively. SCB-AC of 1298 m2/g was produced at optimum condition; ZnCl2 concentration, carbonization temperature and time of 2.19 M, 488.89°C and 95.18 min respectively. The produced AC had an irregular structure consisting of both micropores and mesopores, different functional groups and high thermal stability. The SCB-AC with the highest specific surface area of 1355.7 m2/g can be further applied for the next relevant works.
