Preparation and Properties of Activated Carbon from Palm Shell by Potassium Hydroxide Impregnation: Effects of Processing Parameters

The preparation and characterization of activated carbons (ACs) produced from palm shells, a carbonaceous agricultural solid waste, via potassium hydroxide (KOH) impregnation were studied. The effects of processing parameters: activation temperature (500-1000°C), KOH/char ratio (1:1-3:1) and activat...
