Abstract

1378451 Activated bauxite DU PONT OF CANADA Ltd 11 April 1972 [16 April 1971] 16616/72 Heading C1A Activated bauxite containing 7 to 25% by weight of volatile matter is prepared by heating mill grade bauxite of U.S. standard sieve mesh size 18-30 at 275‹ to 325‹ C. The mill grade bauxite may be heated in a forced air circulation oven and the so formed activated bauxite may be of surface area greater than 250 square metres per gram and may be used as an absorbent for catalyst residues in the production of a polymer of ethylene.
