PURPOSE:A porous calcined granulated carrier having sufficient oil absorption amount, obtained by calcining a kneaded granulated carrier of an organic material such as grain flour, extracted cake, a mold of microorganism, sawdust, resin of acrylic acid, polyvinyl alcohol, etc. CONSTITUTION:A kneaded granulated carrier of any organic material of grain flour such as wheat bran, rice bran, starch, wheat flour, maize flour, etc., extracted cake such as soybean cake, colza oil, bagasse, beet cake, etc., a mold of microorganism such as baker's yeast, lactic acid bacteria, Chlorella, etc., a natural organic substance such as sawdust, cellulose powder, chitin, etc., and an organic substance such as a water-insoluble synthetic resin of acrylic acid, polyvinyl alcohol, etc., is calcined at 600-1,000 deg.C to give a porous calcined granulated carrier. The kneaded organic substance is evaporated by calcination, pores are formed on places wherefrom it is evaporated, and the amount of the organic substance is preferably about 2-25wt%. The carrier has about 30wt% absorption amount.
