Abstract

Fullers earth is a naturally occurring clay which is largely used in the oil industry for clarification and decolourisation, either alone or in conjunction with other adsorbents like activated carbon. Owing to the expansion of the hydrogenated oil industry the demand for bleaching earths is on the increase. Natural fullers earth is not available in India in sufficient amounts. The use of imported varieties of bleaching earths increases considerably the cost of bleaching of oils. Consequently, several workers (2-4) have investigated the suitability of indigenous clays after activation by different methods, for the bleaching of oils. The present paper deals with the results of investigations carried out on the activation and bleaching properties of four clays occurring in Mysore State.
