PP-I-72WAYS OF CARBON SUPPORT STRUCTURE AND PROPERTIES FORMINGMukhin V.M., Gurianov V.V., Zubova I.D., Zubova I.N.JSC “ENPO “Neorganika”, Electrostal, RussiaE-mail: neorg.el@mail.ruThe ways of forming the structure and properties of active carbons (AC), which areintended to use as carbon supports in catalysis, were investigated. It was established that themost perspective raw material for producing such AC is polymeric resins from the class ofthermosetting plastics and packed vegetative raw material (shell and bone of a fruit).At the present moment the fields of application of adsorption technologies based on ACare headily broadening. It is stipulated with three reasons: first, active carbons allow solvingthe sharpest problems of biosphere and harmful emissions; second, they provide a high purityof agents, materials and products; third, they are conductive to introduce manufacturingintensive technologies, including catalysis.For solving of these problems it is necessary to get active carbons having the developedsorbing pore volume (micro and meso pores), high strengthening properties and minimalcontent of ash elements.Such properties of new perspective active carbons may be achieved by means of:- usage of low-ash raw material and its modification with chemical compounds,- special modes of granules forming and their thermal treatment (drying, carbonizationand activation);- deep ash removal of active granules (cleaning).At producing active carbons as carbon supports for catalysts the best results are achievedwith the use of polymeric raw material, bone and shell of fruit trees drupes and anthracites.The perspective polymeric raw materials for carbon support production are phenolformaldehyderesin (carbons of FTD type), polyvinylidene chloride (carbons of PAY type)and furfural copolymers (carbons of FAS type).Table 1 shows the qualitative indexes of polymeric active carbons.135
