Fluidizing a free‐flowing mixture of clay and concentrated sulfuric acid in a medium of hot air at 150 C yields an active product of high apparent bulk density (ABD) and consequent low oil retention unlike the conventional “wet” method of activation which yields a fluffy clay with high oil retention. Comparative data on bleaching capacity, ABD and oil retention of the products obtained by both methods are given.
