Pd/SO4 2-/ZrO2/Al2O3catalysts are prepared and investigated in reaction of isomerization of N-hexane in the work. For comparison Pt/SO4 2-/ZrO2/Al2O3 catalysts are investigated. It is established that in the field of low temperatures (140 °C) the catalyst on the basis of palladium shows high rates comparable to the Pt-containing catalyst. At more high temperatures yielding of isomers for Pd/SO4 2-/ZrO2/Al2O3 catalyst are lower, than for Pt/SO4 2-/ZrO2/Al2O3. However, isomerization depth (the maintenance of a 2, 2-dimetilbutan in mix of C6 isomers) for the palladic catalyst in all studied range of temperatures exceeds for 6-10% a similar indicator for the platinum catalyst. For clarification of the role of condition of palladium the catalysts Pd/Al2O3 Pd/SiO2 were prepared and investigated. It was established that the best indicators are reached on the aluminum oxide systems in which palladium is in the oxidized state. © 2015 The Author Published by Elsevier Ltd.

The method of synthesis of composite materials of aerogel type polyvinyl alcohol/technical carbon with the volume density about 230 kg/m3 is developed. The method of synthesis of such materials consists in foaming of water solution of the polyvinyl alcohol containing technical carbon and nonionic SAS with the subsequent carrying out cycles of freezing defrosting of the received foam and drying at the room temperature. Technical carbon is modified previously before achievement of sour pH and injected into the offered structure in the form of suspension. © 2015 Published by Elsevier Ltd.

The work is dedicated to the construction of kinetics models for the naphtha reforming process and the adjacent process of catalyst regeneration by coke combustion. The proposed kinetic model for the reforming process is based on the use of common rate equations for the groups of similar reactions with account of difference in reaction rates for individual homologs within these groups by simple correlations with thermodynamic properties (first of all - with the values of Gibbs free energy) of individual reactions and by other simplification methods. Such approach gives the way to construct the kinetics models optimal from the point of view of compromise between accuracy and simplicity. The proposed naphtha reforming model is characterized with the high level of kinetic scheme detailization (62 individual and group reactants and 146 individual reactions), at the same it is rather simple and provides the accurate description of the experimental data using only 22 kinetic parameters. This model is thermodynamically consistent and provides accurate description of experimental data in a wide range of process parameters. Account of catalyst deactivation by coke deposition in the model gives the way to simulate transient reforming process performance both in fixed and moving catalyst beds. Kinetics of coke combustion for catalysts with moderate coke content (up to 3% mass) may described by simple kinetic equation with apparent reaction rate orders closed to unit for relative coke content and to 1/2 for oxygen. Demonstration simulations of naphtha reforming and coke combustion processes are presented. © 2013 Elsevier B.V. All rights reserved.

In the series of studied Pd/C catalysts, the highest selectivity for benzyl alcohol formation with complete conversion of benzaldehyde was demonstrated by the sample containing 1% palladium supported on carbon nanotubes when the reaction was carried out at 40 °C and 0.5 MPa. The 0.3% Pd/C catalysts have low activity. Increasing the palladium content and raising the reaction temperature leads to an increase in the toluene fraction in the reaction products. © 2013 Springer Science+Business Media New York.

This month’s Business Trends focuses on five major trends affecting the downstream industry. These include: a forecast on global demand for industrial valves to 2020, how the approval of Chinese teapot refinery crude import licenses could lead to a fuel supply glut, the surge in US ammonia and urea plant construction, the start of Nigeria’s DSDP program and the consolidation of Japan’s refining industry. © 2015 Hydrocarbon Processing.

The compositions of aqueous 2-aminoethanol solutions used in industry for absorption of carbon dioxide resulting from combustion of natural gas have been determined by 1H and 13C NMR spectroscopy. The absorption process does not involve generally accepted paths of thermal decomposition of the absorbent in the reaction with carbon dioxide, but the main path is non-oxidative decomposition of 2-aminoethanol into ammonia and ethylene oxide. Splitting of the NMR signals of carbamate anion formed by reaction of 2-aminoethanol with carbon dioxide has been rationalized by specific structure of the anion due to intramolecular hydrogen bonding. © 2016, Pleiades Publishing, Ltd.

The product distribution for the deep catalytic cracking of C 16-C28 n-alkanes has been studied. Using the method of the temperature-programmed desorption of ammonia, the difference in the acid properties of HZSM-5 and ultrastable Y zeolites and the catalyst matrix components has been found. For the primary cracking of heavy hydrocarbon feedstock to occur, the catalyst matrix must have a high acidity. Bizeolite catalysts exhibit high selectivities for olefins with both normal and branched chains, which are due to a decrease in the contribution of the hydrogen redistribution reaction. For a bizeolite catalyst, the additivity of the selectivities for olefins and aromatic hydrocarbons, depending on the composition of the zeolite component, is observed. © 2010 Pleiades Publishing, Ltd.

Transformations of 2-methylthiophene and benzothiophene together with n-undecane, declaim, or cumene under conditions of catalytic cracking have been studied. It has been found that enhancement of the [H]-donating activity in the order cumene < n-undecane < decalin leads to an increase in the degree of conversion of organic sulfur compounds, predominantly yielding hydrogen sulfide. An increase in the amount of 2-methylthiophene and benzothiophene alkylation and condensation products in the liquid products of cracking is observed in this case. Schemes of conversion of these compounds under catalytic cracking conditions have been proposed. The dependence of the degree of conversion of thiophene compounds into hydrogen sulfide on the ability of the catalyst to mediate hydrogen transfer reactions has been revealed. © Pleiades Publishing, Ltd., 2012.

Chlorine-substituted polymers with a system of conjugated double bonds-polyvinylene chlorides, which form sp2-carbon structures under unusually mild conditions, were prepared by the dehydrochlorination of carbon-chain perchloropolymers (chlorinated polyvinyl chloride and a polyvinyl chloride-poly-vinylidene chloride composition) under the action of potassium hydroxide in organic media. The results of the potentiometric titration of the reaction medium in the synthesis of polyvinylene chlorides and the characterization of the products by Raman spectroscopy and thermal analysis with the mass spectrometry of the volatile products of thermal degradation confirmed the formation of polyvinylene chlorides under the selected dehydrochlorination conditions. It was hypothesized that the observed incomplete dehydrochlorination of the perchloropolymers is explained by the stabilization of polyvinylene chloride structures in the process of their formation by donor-acceptor interaction with an alkaline agent; this is consistent with the ability of the resulting polyvinylene chlorides to reversibly bind KON from solutions. © Allerton Press, Inc., 2012.
