The purpose of the study - to establish the optimal technological parameters of technology nanostructured oxide catalysts oxidative dehydrogenation of aliphatic hydrocarbons and their derivatives, and model representation of the production technology of catalysts. Methods of research - experimental and statistical methods, the study of the catalytic activity of catalyst samples by using a flow reactor model, infrared spectroscopy, potentiometry, fotokolometriya, scanning electron microscopy, gravimetric method, X-ray diffraction and thermal analysis rentgenofluoristsent, derivotografic studies, mathematical modeling. It has been established that the iron-molybdenum catalyst with a minimum content of impurities formed during the deposition process, a "reverse" manner to the determined optimum values of the concentrations of precursor and the acidity of the reaction medium. By using the data of the mathematical model parameters determined opimalnye heat treatment of the initial mass of the catalyst. A new approach is the investigation of surface properties of materials, which is based on the analysis of the interaction of molecular orbitals in the adsorption and solvation kompleks. Developed the basic technological and operational schemes process synthesis of iron-molybdenum catalyst promoted nanodisersnymi TiO2 particles using a model of the process equipment. The proposed technique does not provide for the washing step of the precipitate weight byproduct of the deposition reaction of ammonium nitrate. The decomposition reaction of the salt in the pin, weight plays a positive role of the auxiliary heat source, which reduces costs energy during heat treatment of the precipitate after it is dried.
