Abstract

The article summarizes the results of development of the scientific foundations of preparation of the catalysts, and of the experimental development works on creation of the new technologies of their production with the use of physical models, which were previously created on the basis of fundamental research. The results of the adoption of the new production technologies of the reforming catalysts of the PR series at the domestic plants are presented. The adoption consisted in creation and approbation of the fundamentally new technologies of production of the aluminum hydroxide (AHO) by means of the continuous method, modification of AHO by the elements of IV group, plasticization and forming of AHO in the production of the support, application of H2PtCl6 using the reactions of the ligand substitution of C by the functional groups of the support, and reduction and activation of the catalyst, which provide the optimal chemical com- position. Their operation during the 15-year period is analyzed. The reasons of high selectivity (up to 90%) of the new catalysts are found; the new technologies of the combined processing of mixture of C3-C4 alkanes with C5+ are developed and tested for the production of the high-octane catalysts with selectivity approaching 100%. The main effect of the C5+ yield increase of the end products is achieved by the transformation of the C3-C4 alkanes into the more high-molecular aromatic hydrocarbons. New processes of the combined processing of the mixtures of C3-C4 and gasoline fractions can be considered to be an alternative technology, which solves the important task of broadening the source of raw materials of the motor fuels by the inclusion of the C3-C4 alkanes of little value into the processing.
