PP-<strong>II</strong>-16stages. Kinetic parameters (preexponential factors k 0 and activation energies E a ) forall chemical reactions were calculated by decision of a inverse kinetic problem, thatwas realized in integrated environmental Delphi 7. The data used as input in thecalculation are physic-chemical properties of hydrocarbons, components compositionand product mixture, technological conditions that are obtained from generated inMicrosoft® Office Access 2007 data basis.Diffusion Pe D =2375-1663 and thermal Pe T =2494 criterions Péclet estimationconfirms the possibility usage of ideal spilling reactor for mathematical description ofhydrodynamic regime.For model verification the calculated characteristics of the output flow werecompared to similar experimental values from industrial reactor. The averagedeviation of input concentration did not exceed 4 % that confirms high accuracy ofprocess model kinetic parameters.Method for increasing of efficiency of the linear alkyl benzenes manufacture wasoffered with usage developed mathematical model of dehydrogenation reactor.Influence of water such as inert addition in desired reaction and active continent inreaction of steam-water conversion was investigated. It is shown that waterconcentration was varied within the limits of 2 to 3,5 liter/hour that led to decrease inthe coke concentration up to 2,9 mass %. That dynamics of water delivery allowsextending the life cycle of catalyst 5 %.References[1]. Kravtsov A.V., Ivanchina E.D., Ivashkina E.N. Yuriev E.M.
