Abstract

The present work aims to develop an innovative, alternative, fast, and cost-effective one-step pyrolysis method for activated carbon production using peanut shell and vinasse mixture. This facile procedure is based on single-step carbonization treatment at a temperature range of 400-800 degrees C. Different carbonization time (15-360 min), impregnation ratio (1-3 g/g), impregnation time (3-24 h), and nitrogen flow rate (300 and 600 ml/min) were examined. The chemical and physical properties of the activated carbon examined by SEM-EDX, FT-IR analysis, particle size distribution, iodine number, pH(zpc), BET surface area, and surface functional group analysis by Boehm's titration. The results illustrate that the values of BET surface area, total pore volume, average pore diameter, iodine number, pH(zpc), and carbon content of activated carbon were found as 1290.5 m(2)/g, 0.5667 cm(3)/g, 21.2 angstrom, 1258.4 mg/g, 5.7, and 86.89%, respectively.
