Abstract
The present invention relates to inter alia a method for the pre-treatment of used frying oil from vegetable and animal fats with silica gel. Other inexpensive adsorbents such as activated carbon , aluminium oxide and acid activated bleaching earth can also be used for this purpose. Among the four adsorbents used, silica gel remains the best adsorbent in terms of the colour and the quality of the pre-treated oil. The used frying oil is treated with silica gel in a preferred ratio of 1:1w/w. The pre-treated used frying oil has much lower free fatty acids (FFA) and peroxide value (P.V.) values as compared to the oil before the silica gel treatment. The pre-treatment process is particularly useful for removal of polar components from used frying oil. The pre-treated used frying oil can be refined for non-food applications including biofuel, lubricant , soap and other oleochemical derivatives , or converted into its methyl esters via esterification and transesterification preferably using RH resin and sodium hydroxide. The methyl esters derived from the used frying oil can be used in the production of biodiesel. The invention also discloses a method of regenerating the used adsorbent utilised in, for example, pre-treating the used frying oil.
