As a result of the development of catalysts for the cracking process renewable raw materials in order to obtain components of motor fuels revealed catalytic activity of nanoparticles goethite in this process. It is shown that the maximum output and minimum output alkanes oxygen-containing compounds is achieved at a temperature of 400 0C. The main products of cracking liquid hydrocarbons are gasoline and diesel fractions. For the first time shows the catalytic activity of iron-containing catalyst for carbon nanotubes Fe / CNT in the low-temperature steam reforming of ethanol, hydrogen selectivity close to 50% in the conversion of ethanol 76% (T = 400 ° C). This opens up the possibility of using catalysts on carbon nanotubes at low-temperature conversion of bioethanol derived from renewable raw materials. In order to develop selective catalysts for the synthesis of hydrocarbons from the raw non-oil origin on the results of the research sformulyuvano concept selection selective catalytic synthesis of C3-C4 hydrocarbons in the hydrogenation of carbon monoxide, which is based on the fact that limiting the growth of the carbon chain can be achieved by limiting the size of the active catalyst component and decrease as the size of the metal nanoparticles and nanoparticle distribution of half-width size can lead to a complete cessation of growth of the carbon chain. In the process of esterification of alcohols, including ethanol in order to find ways to improve the selectivity of selective esterification catalyst sulfokationitnyh ethanol shows that the morphology acid catalysts are equally important factor that influences their activity and selectivity than acidity. Based on the analysis of possible mechanisms of SCR process nature and role of the active sites of Ag/Al2O3 was evaluated in the SCR activity. It was established that the role of silver in Ag/Al2O3-catalyst consists in forming of redox and acid-base sites. The activity of Ag/Al2O3-catalysts in the selective reduction of NO is determined by content of silver as cations and nanoclusters. Increase in alumina content up to 45-50% wt in the Ag/Al2O3/cordierite leads to higher activity. The coating method of a honeycomb matrix by mesoporous layer of Al2O3 has developed. Structured Ag/Al2O3/cordierite catalysts characterized by high activity in the SCR of NO in reaction mixtures which are similar to exhaust gases of lean-burn gasoline and diesel engines. The activity of binary Co-In-oxide catalysts in joint reduction of NOx (I, II) with CO and hydrocarbons depends on the content and sequence of introduction of the active components, nature of the suport (Al2O3, ZrO2), the acidic properties of the catalyst surface. The highest activity in NO reduction with CO was achieved on 5%In2O3/5%Co3O4/Al2O3 catalyst. Co-In-oxide catalysts supported on ZrO2 are resistant to water vapor. Introduction of 0,1% Pd in the oxide catalysts decrease the temperature of nitrogen oxides reduction on 120-180°C. Pd-, Со-, Се-, Zr-oxides compositions were developed and Pd/(Co3O4-CeO2 (ZrO2)/cordierite structured catalysts with low content of PGM (0.1%) were constructed based on the compositions. The catalysts may be used for complex purification of exhaust gas from nitrogen oxides and carbon monoxide.
