COMPARATIVE ANALYSIS OF COAL AND COCONUT ACTIVATED CARBON – PDF  (STATISTICS PROJECT TOPICS AND MATERIALS)

 

ABSTRACT

The experiment was carried out to analyze comparatively coal and coconut activated carbon. The coal sample used in bituminous and with density of 1300kg 1m3 tile coconut shell was used. The coal and coconut shell was first activated using phosphoric acid. The activated coal and coconut carbons mere then used to bleach palm oil after preliminary treatment of the palm oil. The 10 dine value, saponification value, peroxide value and acid value of the oil bleached with coal activated carbon and coconut shell activated carbon were determined separately and compared. From the experiment carried out it was discovered that coconut shell activated carbon is a better absorbent than coal activated carbon. The results obtained from the experiments during experiment can be used to dram further inference on the comparative analysis of coal and coconut activated carbon.

INTRODUCTION

1.1 HISTORY OF ACTIVATED 

Activated carbon was first know to treat mater over 2000 years ago. It was first produced commercially at the beginning of the 20th century and was only available in powder form. Initially activated carbon was mainly treatment to remove taste and then from 1930 for mater treatment to remove taste and odor. Granular activated carbon was developed as a consequence of WWI for gas masks and has been used subsequently for mater treatment, solvent recovery and air purification. The unique structure of activated carbon produces a very large surface area.11b of granular activated carbon typically provides a surface area of 125 acres {1kg = 1000000 sq}. Activated carbon be produced from a variety of carbonaceous raw material, the primary ones being coal, coconut shills, mood and lignite. The intrinsic properties of the activated carbon are dependent on the raw martial source. The activated carbon surface is non-polar which results in an affinity for non- polar adsorbates such as organics.

Adsorption is a surface phenomenon in which an adsorbate is held onto the surface of the activated carbon by van der waals forces and saturated is represented by an equilibrium point. These forces are physical in nature, which means that the process is reversible (using heal, pressme etc) Activated carbon also capable of chemisorptions, whereby a chemical reaction occurs a the carbon interface, changing the state of the adsorbate {dechlorination is an example of a chemisorptions process}
