Abstract
This project was carried out using coal sample from Onyeama coal mine Enugu, Enugu State. Activated coal was produced by carbonizing the coal and activating it using phosphoric acid at a temperature of 5500c. the degree of bleaching of raw palm oil was monitored using spectrometric meter through absorbance measurement. The essence was to identify suitability of the coal as a bleaching agent on palm oil. Comparison of the result obtained was made with the commercial fullers earth.
From the result obtained that 0.45mm, 0.18mm and <0.075mm particle size of the activated coal was used at size and at variable temperature of 1200c, 1600c and 2000c were carried out, the average percented colour absorption for the activated coal from Enugu was found to be 80, 81 and 89 respectively. This, the optimal particle size, temperature and weight was obtained to be 0.18mm 2000c and log/100ml of palm oil respectively.
Further it was identified that the smaller the particle size of the activated coal, the higher the percentage colour reduction.
It was also observed that the temperature has a large effect on the bleaching of palm using coal. This percentage colour reduction increase as the temperature increases.
It could be conclude that coal is a poor absorber though if activated properly can used as a bleaching.
