description |
The effectiveness of activated bean husks for the adsorptive bleaching of palm oil was studied in this work. Optimal bleaching parameters like temperature, time and adsorbent-oil ratio were determined for the palm oil decolouration. Various weights of 1, 1.5 and 2 g of activated beans husks were contacted with crude palm oil at 50, 80, 110, 140 and 170 °C and contact times of 45, 60 and 90 minutes using 20 ml of oil sample in each case. The decolorizing effect increased linearly with temperature. Optimal adsorption conditions gave a bleaching efficiency of 98%. Langmuir, Freundlich, Temkin with Dubinin-Radushkevich isotherms were correlated, and Freundlich has the highest statistical correlation coefficient (R2) value of 0.9901. Dubinin-Radushkevich isotherm suggested chemisorption. The pseudo-second-order model provided the best fit for the kinetic study.
