AbstractThe influence of polar particle centers, in particular, halogen ions adsorbed on the surface of a reactor, and water molecules present in pores and microcracks on the reactor surface on the low-temperature oxidation of hydrogen and organic compounds was simulated. Within the framework of a proposed model, it was shown by appropriate calcula...

AbstractProcess modeling and design of the ethylene oxide production plant is mainly depended on the kinetics of the ethylene oxide production reactions. In this article, the kinetics equations for partial oxidation (epoxidation) of ethylene on silver catalyst were reviewed. There are three competitive reactions in this system: ethylene partial and...

The effect of the oxidation degree of a nickel foil surface on the rate of catalytic oxidation of ethylene was studied by a pulse method at 600 and 700°C. It was shown that a reduced metallic surface demonstrated a high activity in partial ethylene oxidation, whereas a partially oxidized surface with an oxidation degree of ~24 formal O2 monolayers,...

AbstractMixed oxides 1%Cs/MgxCo3–xO4 (х = 0–0.9) with a spinel structure are synthesized by precipitation from nitrate solutions using (NH4)2CO3 as the precipitating agent and the subsequent modification of the dry precipitate with cesium by the Pechini method and calcining. The synthesized samples are studied by XRD, BET, SEM, TPR, and TPD methods...

AbstractThis review—which is based on the authors’ original studies—is devoted to application of aqueous solutions of Mo–V–P heteropoly acids (HPA-x, where x is the number of vanadium atoms) as bifunctional (acidic and oxidative) catalysts. The focus is on the development of one-pot processes in which the acid-catalyzed reaction of diene synthesis ...

AbstractFor an industrially significant process of the catalytic reforming of gasoline, an increase in the octane number of gasoline and limitations on the concentrations of aromatic hydrocarbons and benzene are the most important problems. To solve these problems, an analysis of the reactor unit based on a detailed kinetic model of the process was...

AbstractTo study the role of the reactions of CH3O2 radicals in the unsteady process of formation and propagation of methane combustion waves in air at P = 1 atm, the reactions were mathematically simulated using a kinetic model complemented with a block of these reactions. The influence of this block is limited by the decomposition reaction СН3О2 ...

AbstractIn this study, Co–La–Mo–B catalyst used for hydrogen production by hydrolysis of sodium borohydride (NaBH4) solution was synthesized by chemical reduction method. Characterization of the synthesized catalyst was carried out with EDX and XRD. In hydrolysis experiments, the effect of parameters such as molybdenum, NaOH and NaBH4 concentration...

AbstractMonometallic copper and bimetallic palladium–copper catalysts supported on ZnO–Al2O3, CeO2–Al2O3 and ZrO2–Al2O3 were prepared by conventional impregnation method and tested in the methanol synthesis reaction in a gradient less reactor under elevated pressure (3.5 MPa) at 220°C. The physicochemical properties of prepared catalytic systems we...
