Реферат: A technology has been developed for producing porous carbon materials in the form of granules with a diameter of 0.5–0.8 mm with a micro-mesoporous texture. An aqueous solution of furfuryl alcohol was used as a dispersion medium, followed by heat treatment in inert, hydrocarbon and oxidizing atmosphere for the development of a microporous texture at the granule formation stage using the granulation and extrusion methods of carbon black. A technology has been developed for modifying the texture of a mesoporous carbon material in the form of honeycomb blocks, which ensures the production of a carbon sorbent with a uniformly microporous texture. The technology consists of the impregnation of mesoporous Sibunit by furfuryl alcohol solutions in water, followed by polymerization and carbonization of the applied layer. Polymerization of FA and carbonization occur in the largest pores of the carbon matrix (30-50 nm), which act as nanoreactors. This leads to the formation of a uniform microporous structure with a pore size of 3-5 nm. It is shown, a modified Sibunit with a homogeneous microporous texture has molecular sieve properties in separating a mixture of gases CO2 + CH4.
