113 Effect of the Composition and Structural and Size Characteristics of Composites Based |
Authors: | S. N. Orlyk and T. K. Shashkova | |
Summary: | The effects of transition metal (Cu, Co, Ni) oxides and platinum-group metals (Pt, Pd, Rh) in composites based on Y(Sc)-stabilized zirconia on their catalytic properties (activity, selectivity, sulfur resistance) and service life characteristics (thermal stability, performance stability) in methane oxidation reactions have been investigated. The high activity of the composites (75–99% methane conversion at 600–800C) correlates with the amount and mobility of surface oxygen in these materials. The promoting effect of the platinum-group metals depends on the composition of the reaction medium (on whether it corresponds to the partial or total
methane oxidation and on whether it contains sulfur dioxide). | |

113 Effect of Additives La2O3 AND CeO2 on the Activity and Selectivity of Ni-Al2O3/Cordierite Catalysts in Steam Reforming of Methane |
Authors: | Ie. V. Gubareni, Ya. P. Kurilets, S. O. Soloviev | |
Summary: | The introduction of rare-earth elements (CeO2 and La2O3) into Ni-Al2O3/cordierite catalysts permits a decrease in the water to methane ratio in the reaction mixture for the steam reforming of methane. The carbon dioxide content in the resultant synthesis gas is considerably decreased in the presence of Ni-CeO2-Al2O3/cordierite catalysts, which may be attributed to suppression of the water–gas shift reaction. | |

113 113 Activity and Stability of Multicomponent Nickel-Containing Catalysts Supported on Zirconia in the Steam Reforming and Oxidative Steam Reforming of Butane |
Authors: | M. R. Kantserova, V. I. Chedryk, S. N. Orlyk
| |
Summary: | The introduction of copper and CeO2 into nickel-containing catalysts supported on zirconia stabilized by scandia and ceria (ScCeSZ) provides for their stable activity and enhances their resistance to coke deposition in the steam and oxidative steam reforming of butane. The presence of oxygen in the reaction mixture decreases coke deposition on the surface of these catalysts and reduces the temperature required to achieve complete butane conversion in the presence of a Ni-Cu-CeO2/ScCeSZ composite | |

113 Effect of the composition of an oxide coating and the preparation method of block catalysts on their activity in the deep oxidation of methane |
Authors: | M. R. Kantserova, S. N. Orlik, A. V. Shvets | |
Summary: | Deep methane oxidation catalysts containing 3d metal (Mn, Co), rare-earth (La) and alkali-earth (Ba, Sr) oxides in the porous matrices of secondary supports (Al2O3, ZrO2, and their binary composition) formed on honeycomb blocks (cordierite, kaolin-aerosil) are studied by means of X-ray powder diffraction, the thermal desorption of nitrogen, and temperature-programmed reduction with hydrogen. It is shown that the activity and stability of the catalysts depend on the method for their preparation and the nature of the active components and secondary and block supports. After life cycle tests, the proposed catalysts with 80–100% conversion of methane into CO2 at temperatures of 650–750°C can be recommended for use in systems for the catalytic purification of gases containing hydrocarbon admixtures (methane and C2–C4 homologues) and the combustion of hydrocarbon fuels in industrial and household catalytic heat generators. | |

113 Effect of composition and preparation method of (Pd), Co, Ce, Zr –metal-oxide catalysts on their activity in the reduction of nitrogen (I), (II) oxides with carbon monoxide |
Authors: | T.M. Boichuk, P I. Kirienko, S.M. Orlyk, S.O. Soloviev | |
Summary: | Among the studied (Pd), Co-, Ce-, Zr-oxide catalysts including catalysts deposited on structured cordierite support, the catalyst prepared by co-deposition of ceria and cobalt oxide is characterized by higher activity in reaction of reduction of nitrogen (I), (II) oxides (CO + NO, N2O + NO + CO) compared with samples prepared by successive deposition. This may be caused by an increase in both mobility of surface oxygen and dispersity of components in the catalytic composition. | |

113 Effect of CeO2 and Al2O3 on the activity of Pd/Co3O4/cordierite catalyst in the three-way catalysis reactions (CO/NO/CnHm) |
Authors: | S.O. Soloviev, P.I. Kyriienko, N.O. Popovych. | |
Summary: | The present article studies the effect of CeO2 and Al2O3 on the activity of Pd/Co3O4/cordierite catalyst in conversion of NO, CO, CnHm. The catalysts were characterized by temperature programmed reduction with hydrogen, X-ray diffraction, X-ray photoelectron spectroscopy and transmission electron microscopy. It is shown that the effect of CeO2 on the properties of Pd/Co3O4/cordierite catalyst depends on preparation method. The catalyst obtained by co-deposition of cerium and cobalt oxides has higher activity in CO oxidation (CO + O2 and CO + NO) and total hexane oxidation (C6H14 + O2). Such phenomenon is probably caused by more than stoichiometric amount of formed oxygen vacancies, an increase in both mobility of surface oxygen and dispersity of components in the catalytic composition. It is demonstrated that CeO2 addition promotes the SO2 resistance of Pd/Co3O4/cordierite. The second support decreases the activity of Pd/Co3O4/cordierite catalyst in the reactions of CO and C6H14 with oxygen because of CoAl2O4 formation. | |

113 Tri-reforming of methane on structured Ni-containing catalysts |
Authors: | S. A. Solov’ev, Ye. V. Gubareni, Ya. P. Kurilets, S. N. Orlik
| |
Summary: | We have studied the process of methane tri-reforming (MTR), which is s synergistic combination of steam and carbon dioxide reforming together with partial oxidation of CH4 on a single catalyst. We have established that structured catalysts Ni/(CeO2, La2O3)/Al2O3/cordierite enable stable occurrence of methane tri-reforming with high conversion of CH4 and CO2. The positive effect of oxygen may be associated with formation, on the surface of the catalyst, of local “hot zones” favoring the occurrence of the endothermic reactions of carbon dioxide and steam reforming. By varying the content of the components in the reaction mixture (O2, H2O, CO2), we can control the H2/CO ratio (1.4-2.5) in the synthesis gas and the thermal conditions of the process, including carrying it out under autothermal conditions. | |

113 113 Designing a structured catalyst for selective reduction of O2 by hydrogen in the presence of NO |
Authors: | S. A. Solov’ev, P. I. Kirienko
| |
Summary: | The influence of the promoter (Pd) modifying additives of oxides of rare-earth (La2O3, CeO2) and transition (NiO, CuO) metal oxides on the catalytic activity of Co3O4/cordierite in reactions of O2 and NO reduction by hydrogen was studied. Introducing Pd and rare-earth metal oxides into the composition of cobalt oxide catalyst results in an increase in its activity in H2 + 1/2O2 → H2O, H2 + NO → 1/2N2 + H2O reactions and an increase in selectivity upon oxygen reduction by hydrogen in the presence of nitric oxide, due possibly to a decrease in the strength of oxygen bounds with the surface and the formation of low-temperature forms of oxygen, which is not typical of unpromoted cobalt oxide catalyst. A structured Pd-Co3O4-La2O3/cordierite catalyst was developed that surpasses the commercial granulated silver-manganese catalyst used in industry to purify the technological gases used in the production of hydroxylamine sulfate of oxygen impurities with reference to activity and selectivity (in the process of oxygen reduction in the presence of nitric oxide), and to thermal stability | |

113 Effect of CeO2 on the properties of the Pd/Co3O4/cordierite catalyst in the conversion of CO, NO, and hydrocarbons |
Authors: | P. I. Kirienko, S. A. Solov’ev, S. N. Orlik | |
Summary: | The effect of CeO2 on the properties of the Pd/Co3O4-CeO2/cordierite catalyst is a function of the method of its preparation. The catalyst obtained by the simultaneous deposition of cerium oxide and cobalt oxide showed high activity in the oxidation of CO (CO + O2, CO + NO) and extensive oxidation of hexane (C6H14 + O2). This behavior is due to the increased mobility of surface oxygen and increased dispersion of the catalyst components. | |
