PCT No. PCT/FR94/01061 Sec. 371 Date May 8, 1995 Sec. 102(e) Date May 8, 1995 PCT Filed Sep. 8, 1994 PCT Pub. No. WO95/07753 PCT Pub. Date Mar. 23, 1995The porous granular material according to the invention comprises carbon, silica, water-soluble mineral salts and water-insoluble mineral salts, does not disintegrate in the presence of water and has a particle size of approximately 1 to 5 mm, preferably from 1 to 3 mm, in particular from 1 to 2 mm; a crushing strength, or mechanical strength, in the range of 0.75 to 1 MPa; a density of between 0.7 and 0.8; a BET specific surface area of between 100 and 200 m2/g; a microporous volume of between 0.25 and 1 cm3/g; and a carbon content of 8 to 11 weight %, the balance being essentially made up by a mineral matrix of base nature, comprising a crystalline phase of insoluble aluminosilicates. Application, in particular, to the purification of liquids, as a catalyst in oxidation reactions and in the manufacture of composite catalysts, in particular in petrochemistry.
