Adsorption of Phenol from Wastewater in Fluidized Bed Using Coconut Shell Activated Carbon

Abstract

Phenol is the major pollutants in the wastewater from various industries such as coal conversion process, fertilizers, petroleum refineries, coking plants, pharmaceutical, dye manufacturing etc. In the present study coconut shell activated carbon is used as an adsorbent. The adsorption is carried out in a fluidized bed. Coconut shell has been used for the preparation of absorbent. The effect of various parameters like concentration, fluid flow rate and adsorbent particle size has been studied. It is observed that as the concentration increases the percent saturation of adsorbent increases. Also increase in fluid flow rate gives better adsorption in case of coconut shell activated carbon. However, it is also observed that percent saturation of adsorption decreases with increases in particle size of adsorbent. In the present study particle size of 0.420 mm is found more beneficial.
