PP-I-25 POROUS CARBON PRODUCED BY LOW-TEMPERATURE DEHYDRO-HALOGENATION AND HEAT TREATMENT OF CARBON-CHAIN POLYMERS Kryazhev Yu.G., Drozdov V.A., Senkevich S.I., Bukalov S.S. 1 , Likholobov V.A. Institute of Hydrocarbons Processing SB RAS, Omsk, Russia 1 A.N. Nesmeyanov Institute of Organoelement Compounds RAS, Moscow, Russia E-mail: kriajev@incat.okno.ru Synthesis of porous carbon with high adsorption ability on the basis of carbon-chain halogenated polymers (polyvinylidene fluoride, polyvinylidene chloride, polyvinyl chloride, etc.) has been carried out in three stages: low-temperature processing by the strong bases (dehydrohalogenation) of polymeric precursor and subsequent heat treatments: carbonization (in the inert atmosphere) at temperature up to 400-600 0 C and activation (up to 950 0 C). For selection of the activation conditions the method of step pyrolysis gas chromatography in various gaseous mediums was used. It has been shown, that the received carbon structures possess high reactivity at the gasification with agents both of oxidizing and reducing character. The conditions of achievement of high values of a specific surface (∼1800 m 2 /g), porosity (∼ 2cm 3 /g) and adsorption capacities on benzene vapor (∼1100 mg/g) are found as a result. The dehydrohalogenation was conducted in the polar organic solvents in the presence of alkaline metals hydrates or alcoholates as in a solution of initial polymer when the maximal depth and uniformity of transformation is reached, and in the heterogeneous conditions with preservation of morphology of an initial material, in particular, fibres. Dehydrohalogenation of polyvinylidene fluoride and polyvinylidene chloride at similar conditions was used earlier for synthesis of linear - chain carbon (carbyne) [1]. According to the data of Raman spectroscopy (He-Ne laser, λ=632,8 nm) the polyene structures (systems of the conjugated double bonds) prevail in the products of chemical lowtemperature dehydrohalogenation. At the raised temperatures these structures are easily transformed to typical disordered graphitic carbon in which the porous structure develops at the subsequent gasification. The investigation of the textural characteristics and properties of produced samples was performed by N 2 (77 K), CO 2 (273 K) and H 2 (77 K) adsorption method. The characterization 166
PP-I-25 of microporous structure was based on the theory of volume filling of micropores (TVFMP). The characterization of mesopores was based on the Derjaguin-Broekhoff-de Boer (D-BDB) method with the purpose of calculation of formal pore size distributions (PSD). The received adsorption branches isotherms were additionally processed by the method of the non-local density functional theory (NLDFT). The samples of porous carbon have clearly demonstrated high volume of ultra- and supermicropores (0.4-0.7 сc/g). The calculated PSD (according to NLDFT-N 2 ) show the narrow form (0.6-1.2 nm). The mesopores volume is insignificant after heat treatment in the inert medium, but as the result of gasification it reaches greater sizes (up to 1,4 cc/g). It is interesting, that carbonized samples already possess the considerable micropores volume which naturally increases during activation without essential change of their structural heterogeneity. The received samples possess higher adsorption capacity on hydrogen (α) at atmospheric pressure and 77 K (up to 1,8 % mass.) than well-known carbon adsorbents with comparable values of specific surface. A linear relation between values of α and the ultramicropore volume (СО 2 micropore volume) for the synthesized samples of porous carbon was found. The same straight-forward correlation has been obtained for carbon systems with various structure and morphology [2]. The obtained data allow to assume, that the sizes and a positional relationship of the structural elements of porous carbon in a considered case are determined by the lowtemperature stage of the synthesis because the stabilized structures with system of the conjugated double bonds are formed.
