PP-II-121SUBSTANTIATION OF STRUCTURE OF THE CATALYST OXIDATIONS OFPROPANE IN ACROLEINSinelnikov A., Sсhukin V.The Toglyatti state university, Toglyatti, RussiaE-mail: Schukin_V@tltsu.ruThe problem of catalytic transformations of less scarce raw material - the lowest limitinghydrocarbons contained in natural, passing and industrial (torch) gases in valuable substancesis considered. In particular, by the example of propane it is shown, that synthesis of catalystson the basis of the ions accelerating reaction of synthesis acrolein with their subsequentupdating by ions, accelerating reaction dehydrogenation propane has allowed to receive thestructures possessing the greater activity and selectivity in comparison with a line of othercatalysts, tested in reactions of one-phasic synthesis acrolein.Because of essential increase of the prices for oil which is initial raw material for varioustechnologies, last years interest to catalytic transformation of less scarce raw material - thelowest limiting hydrocarbons contained in natural, passing and industrial (torch) gases hasconsiderably increased.Heterogeneous transformation of limiting hydrocarbons can occur in directionsdehydrogenation, oxidations, dimerization, condensation to education of some valuableorganic connections which reception on the basis of traditional sources of raw material iseconomically less favourable.Transformation of limiting hydrocarbons can pass with appreciable speed only at thehigher temperatures, with low selectivity on target substances and difficult structure ofreactionary gas. The successful decision of a problem is absence of laws of selection ofcatalysts for selective oxidation of limiting hydrocarbons, and the mechanism of reaction isinvestigated much less, than corresponding nonlimiting.The most perspective hydrocarbons are ethane and propane. From them it is possible toreceive ethylene, propylene, formaldehyde, acrolein and other valuable substances.Selection of catalysts for one-phasic synthesis acrolein has not given essential results thattestifies to more difficult mechanism of the given reaction [1, 2, 3]. However, if to assume,that synthesis acrolein occurs through an intermediate stage dehydrogenation propane, thenthe qualitative way of the further perfection is catalysts of one-phasic synthesis acrolein. Theirstructure should include the components accelerating a stage dehydrogenation of propane andcomponents, oxidizing propylene to acrolein.386
