Abstract

This study visualizes the effects of independent parameters on the preparation of activated carbon from hazelnut shell via ultrasound assisted KOH impregnation. The effect of operational parameters including particle size (0.78-1.85 mm), ultrasonic power density (2-190 W/L),
impregnation ratio (0.015-0.06 g/mL), impregnation time (37-143 min), activation temperature (661-839 0C) and activation time (18-72 min)
on the surface areas of prepared activated carbon were investigated. Based on the results, the activation temperature and activation time have a
positive effect, while particle size and impregnation ratio have a negative effect on the surface areas of prepared activated carbon. The surface
area was increased by increasing activation temperature and activation time, but decreasing particle size and impregnation ratio.
