AbstractThe effect of copper compounds and phosphorus–molybdenum–vanadium heteropoly acids (HPAs) H5PMo10V2O40 and H7PMo8V4O40 used as cocatalysts in the cooxidation of propane and CO in the presence of rhodium, palladium, and platinum compounds in an aqueous AcOH medium has been studied. It has been shown that these HPAs are fairly effective; howe...

AbstractSteam Reforming of Methane, which converts natural gas into products with higher economic value in the presence of a suitable catalyst bed reformer, is the most economical method for hydrogen production in petroleum refineries. This study focuses on developing a Computational Fluid Dynamics (CFD) model of a steam methane reformer. To this p...

AbstractA study of methanol steam reforming (MSR) in the presence of a Ni0.2–Cu0.8/Ce0.3Zr0.7O2-δ catalyst in conventional and membrane reactors has revealed that the hydrogen yield in a reactor with a Pd–Cu membrane is higher than that in a conventional flow reactor. It has been shown that the Pd–Cu alloy membrane exhibits high hydrogen permeabili...

AbstractTo support the industrial design and process development for the separation of xylenol isomers from coal tar, the present work was focused on 2,4/2,5-xylenol mixture as 2,4-xylenol and 2,5-xylenol have very close boiling points. Specifically, the kinetics of the alkylation of 2,4/2,5-xylenol mixture was investigated that formed the first st...

AbstractMathematical models of methane decomposition during its pyrolysis, including nonstationary diffusion equations with and without taking into account the convective component of the decomposition process, have been developed and verified. Their exact analytical solutions have been obtained and further used in the study of a mathematical model...

AbstractThis research is devoted to a catalytic process using the H-ZSM5 catalyst for the conversion of methyl and ethyl acetate to hydrocarbon aromatics. These reactions are carried out in a fixed bed reactor under atmospheric pressure at 370°C. The distribution of products was measured by GC-Mass spectrometer. The variation of weight hourly space...
