▎ 摘　　要

NOVELTY - Inventions relate to nanotechnology and may be used to manufacture catalysts and sorbents. Graphene pumice contains graphenes arranged in parallel at distances of more than 0.335 nm, and amorphous carbon as a binder at their edges, with the graphene-binder ratio from 1:0.1 to 1:1 by mass. The specific area of the surface is more than 1000 m2/g. The absolute hardness is 1 unit by the Mohs scale and less, specific density is 0.008-0.3 g/cm3 for solids, loose specific density of 0.005-0.25 g/cm3 for granules. The composition is produced by burning of a homogeneous powder mix of graphite oxide, unstable organic material and organic and inorganic metal salts with the moisture of all components of 10-15% in a heat-resistant open or tight mould. The source material for the binder is represented by chemical compounds capable of being in a liquid state up to 180 degrees C, not soaking the graphite/graphene surface and damaged at a temperature of not more than 800 degrees C. Graphene pumice is activated by restoration in hydrogen at 400-450 degrees C and pressure of 0.05-0.11 MPa for 10-30 min or in methane at 800-950 degrees C for at least 1 hour at atmospheric pressure with subsequent cooling. USE - Nanotechnologies. ADVANTAGE - Produced sorbents make it possible to multiply increase the capacity of reservoirs for the storage and transportation of natural gas.15 cl, 8 dwg, 2 tbl, 4 ex
