Research Projects - zeolite and mesoporous molecular sieves (MMS) MCM-48, SBA-15 and KIT-6 silica-carbon composites, carbon and polymer replica.
Objective - develop ways to obtain and study of new materials based on different in nature (inorganic and carbonic) , micro-and mesoporous molecular sieves for the storage of hydrogen and its receipt by the allocation of gas mixtures. Research methods - X-ray diffraction analysis, IR- spectroscopy, volumetric method of measuring the adsorption of nitrogen, methane and hydrogen gases, etc., the method of frontal chromatography.
The comparative study of adsorption of nitrogen and hydrogen (Sorptomatic 1990, 77 K),zeolite the original matrices MCM-48, SBA-15, KIT-6 and final carbon replica - CMK-1, CMK-3 and CMK-8, respectively. The relationship between the nature of organic precursors and structural-sorption properties of the matrix product of carbonization at MMC: in the case of sucrose reached the highest spatial and stimulated the development of surface pyrolysis of acetonitrile - partial graphitization, the conditions of carbonization and pFF and pDVB- the greatest formation of micropores and increase affinity to the surface hydrogen. These factors, as well as steaming postsynthesis (Vpor = 2.0 cm3 / g, SBET = 2350 m2/ g) contribute to hydrogen adsorption to 2.23 wt %. (1 atm, 77K at 20 atm is expected to 6% wt.).
As a result, comparative study of gas adsorption of H2, N2, CH4, CO and CO2 in the selection process of adsorption of hydrogen from pyrolysis gases revealed a significant impact nature of the surface shape and volume of micropores, particularly the growth efficiency of separation of the components in the presence of acidic Brensted and narrowings in the micropores CT, increasing the volume of micropores and specific surface area carbon materials.
The conditions for obtaining hydrogen by adsorption of its selection of typical pyrolysis gas composition. A combined adsorption-chromatographic methods without carrier gas and using hydrogen as carrier gas and the corresponding technological scheme of separation of components of pyrolysis gas at high (30 atm) pressure and hydrogen evolution, combining frontal and displacement separating. Methods of implementing the efficient use of adsorbents of overpressure and obtaining pure gases - hydrogen and methane in one cycle. Patents for inventions were got № 82940 -83109.
