Decolourization process of neutralized sunflower oil was carried out with activated carbon products obtained from pyrolysis liquid products. The effect of parameters such as time, temperature, moisture and dosage on bleaching sunflower oil was investigated. It was found that activated carbon samples are an effective adsorbent for decolourization process of sunflower oil. It was determined that the ability of adsorption of the activated carbon samples at 20 °C temperature is higher than that of the bleaching earth which is used for this purpose. The analysis results directly prove that activated carbons remove the unwanted pigments and residues from sunflower oil. Moreover, activated carbon sample A2 has a more positive effect on pigment removal than other activated carbon samples (A1 and A3). 1% of activated carbon sample A2, 0.01% sunflower oil moisture, 20 °C temperature and 30 min contact time are optimal values in a sunflower oil bleaching process. Therefore, these activated carbon samples can be used to bleach sunflower oil instead of bleaching earth.
