Abstract
Orange peel is a major waste of the food processing industry in Egypt, one of the six largest orange peel producers of the world. The purpose of the current work was to evaluate the oil sorption capacity of dried raw orange peel waste (OP) and thermally modified orange peel waste (TMOP). The effect of oil type, sorption time, particle size and reusability on the oil uptake of raw dried orange peel was assessed. Results have indicated that the oil sorption capacity of OP ranged between 3 to 5 g/g at 25°C, while its water uptake was found to be below 1g/g. Orange peel could not be used for more than 5 oil sorption cycles. Compared to OP, limited percent increase in oil sorption capacity (18-40%) was observed after the thermal modification of orange peel. According to the results presented, dried orange peel waste losses its inherent oil selectivity after carbonization.
