Studies on the acid activation of Bentonite Clays

Fuller’s earth and acid activated Bentonite Clays are used for decolorizing dark oils. They are largely used for the industrial processing of vegetable, animal and mineral oils. The purpose of this paper is, to execute investigations on four Bentonite samples from Iran to determine the beneficiability as well as the possibility of its activation by sulfuric acid in order to produce industrial samples of bleaching earth for bleaching tests with vegetable and mineral oil.
