Title: Production of Activated Carbon from Palm Kernel Shell for Gold Adsorption Using Leachates from Cocoa Husk Ash (Crude Potash) As Activating Agent
Authors: Meteku
Issue Date: 20-Mar-2013
Abstract: Activated carbon, a porous amorphous industrial adsorbent used extensively in gold mine operations in Ghana was prepared from the agricultural waste, palm kernel shell using crude potash leached from another agricultural waste; cocoa husk ash as the chemical activating agent. The effect of impregnating ratios (I.R.), impregnating temperatures (room temperature and 85°C) and carbonisation/activation temperatures (600°C - 800°C) on the quality of the produced granular activated carbon was investigated. The produced activated carbons of particle sizes between 1190μm and 2380μm recorded a mean fresh carbon activity of 91.67% for samples impregnated at 85°C and activated at 800°C at an I.R. of 1.0. An ash content of 2.95 - 6.68% was obtained for the produced GAC impregnated at both room temperature and 85°C. The apparent density of the samples ranged from 0.22 – 0.69g/mL. The quality of the activated carbon was not affected to any significant degree by impregnating temperatures.
