METHOD OF MANUFACTURE OF THE COMPOSITE MATERIAL MADE ON THE BASIS OF THE EXPANDED GRAPHITE Russian patent published in 2007 - IPC C01B31/04 

FIELD: chemical industry; methods of manufacture of the composite materials on the basis of the expanded graphite.

SUBSTANCE: the invention may be used at manufacture of the adsorbents, the porous carbon carriers and the metal=containing catalytic agents. The method provides, that first prepare the 1-2 % cellulose solution in the 5-8.5 % sodium hydroxide water solution. The produced solution is mixed with the expanded graphite in the mass ratio of the graphite to the cellulose of (1-2.5) : (2-1) accordingly. The composition prepared this way is carbonize with heating rate of 4°С per a minute up to 600°С maintaining this temperature within 1 hour. To impart the composite material the catalytic and adsorption properties the cellulose solution may be added with 2-5 mass % of the modifying compound of the transition metal in terms of the metal. The invention ensures simplification of the composite material production process, the improvement of its quality due to the homogeneity of allocation of the active carbon in the lower die of the expanded graphite.

EFFECT: the invention ensures simplification of the composite material production process, the improvement of its quality.
