Already commercialized and some of the most promising technologies of nitrogen oxide reduction in automotive diesel exhaust are compared. The Boreskov Institute of Catalysis (Siberian Branch, Russian Academy of Sciences) is developing an advanced method for the selective catalytic reduction of NO x with synthesis gas produced on board by the catalytic conversion of diesel fuel. The activity of the Ag/Al2O3 catalytic system in NO x reduction by H2 + CO admixtures is studied for both a model composition of the exhaust gas and under real diesel operation conditions. 相似文献

Low-temperature steam conversion (LTSC) of a methane-butane mixture (95% methane and 5% butane) into a methane-rich gas over an industrial Ni-based catalyst has been studied with the following reaction conditions: temperature 200–320°C, pressure 1 bar, gas hour space velocity 1200–3600 h–1, and steam to carbon ratio 0.64. A three-step macrokinetic model has been suggested based on the kinetic parameters found. The model includes the following reactions: (1) irreversible steam reforming; (2) CO2 methanation, which occurs in a quasi-equilibrium mode at temperatures above 260°C; (3) hydrogenolysis of propane and butane, which is essential at temperatures below 260°C. Steam reforming was shown to limit the overall reaction rate, whereas hydrogenolysis and CO2 methanation determined the product distribution in low- and high-temperature regions, respectively. Temperature dependencies of the product distribution for the LTSC of a model ternary methane-propane-butane mixture (85% methane, 10% propane, and 5% butane) have been successfully simulated using the three-step model suggested. 相似文献

The present state of theoretical and experimental investigations of the light scattering near phase transition points in solids is reviewed. It is emphasized that the results available here may be understood on the ground of a simple but rather general phenomenological or semiphenomenological theory. From this point of view the anomaly of the total (integrated) light scattering intensity is considered with account taken of a coupling of the order parameter to other quantities including elastic strains and long-range electric fields. The temperature dependence of the scattered light spectral distribution is discussed in detail, the main attention being given to the so-called central peak problem. The influence of defects both on the total intensity and on the spectral distribution of the scattered light is also examined. 相似文献

The carbon dioxide reforming of methane in a cell with a solid oxygen-conducting electrolyte:
has been studied. The effect of anodic current (or electrochemical oxygen pumping to the reaction zone) on the catalytic
properties of the Pt electrode for CO2−CH4 reaction is discussed. 相似文献

By the semi-empirical interacting bonds method, the heats of oxygen and hydrogen adsorption in a dissociative form on the (100) face of Cu, Ag, Ni, Pd and Pt have been calculated. It has been shown that most stable are the multiply bonded adsorption forms. For the different bonding states, the heat of hydroxyl group formation from O2 and H2 varies but slightly. The calculated values are compared with the experimental data.

Field emission microscopy and thermal desorption studies of hydrogen adosrption on a monocrystal tip and a polycrystalline rhenium wire indicate dissociative adsorption which proceeds with an initial sticking coefficient of So0.2 and an isosteric adsorption heat of about 138 kJ/mol.

Oxygen adsorption on Ag/Au alloys has been studied by field-emission microscopy (FEM). A decrease in the silver concentration of alloy is accompanied by a drastic fall in its ability to absorb oxygen. Using the interacting bonds method (IBM), the adsorption heat of atomic oxygen on the (100) plane of the silver-gold alloy has been calculated.
