  • Porous carbonaceous material
    Patent number: 4978649
    Abstract: The present invention relates to physical chemistry.The material is made as a three-dimensional matrix with a pore volume of from 0.2 to 1.7 cm.sup.3 /g. The matrix is formed by bent layers of carbon of 100-10,000 .ANG. thickness and 100-10000 .ANG. radius of curvature. The true density of the material according to the present invention is 1.80-2.10 g/cm.sup.3, its X-ray density is 2.112-2.236 g/cm.sup.3, the pore size distribution has its maximum within the range of 200-2,000 .ANG..The present invention can be useful in, for example, in the production of catalysts.
