ABSTRACT
This project was carried out using acid activated coal from Enugu coal and the production of ve4getablew oil was monitored using spectrophotometer to measure the absorbance. It was also perform to check the suitability of activated Enugu coal as a bleaching agent for palm oil.
The Enugu coal samples were collected, size reduced, carbonized and activated with acid (phosphoric Acid) before being used for the bleaching process. The bleaching process lasted for 40minutes and it was absorbed that activated coal is a poor absorber of palm oil.
From the result obtained, it was observed t6hat at different temperature rang of 120oc, 150oc and 180oc of 10g of activated coal mixed with 100ml of palm oil, that the co lour absorbance were 1.65, 1.2 and 0.4 respectively. The optimum amount of 10g at bleaching temperatur4e of 180ocfound to be the best for better bleaching.
It was observed that as the temperature increase, the pe4rcentage colour reduction of the oil increase. Beside, it was observed that the smaller the particle size of the activated coal samples, the higher their effect on the oil and the higher the percentage colour reduction.
