Summary

Detailed description has been given of a laboratory method for determining oil retention by bleaching earths and carbons. The method involves determination of the increase in weight resulting when a sample of the bleaching material is treated with oil and the excess oil removed by suction in a stream of hot inert gas under standardized conditions. The oil retention values obtained by this method fall within the range of those observed under practical conditions of plant operation.
