AbstractThe influence of the chemical composition of microspherical nickel–cobalt catalysts on aluminosilicate and aluminum oxide supports on the catalytic characteristics of methane oxidative conversion to a hydrogen-containing gas was studied on a pulse laboratory installation with separate supply of the feed and oxidant. The physicochemical and ...

AbstractThe features of cyclic adsorption processes are considered and the fact of necessity to predict a decrease in the dynamic activity of adsorbents during their operation is exhibited. By analogy with recycling chemical processes, phenomenological concepts of the general pattern of sorbent deactivation were developed, which made it possible to...

AbstractPhotochemical, chemical, and plasma chemical procedures for preparing digermane were studied experimentally. The plasma chemical procedure in corona discharge is the most promising. The kinetic curves of the digermane synthesis in corona discharge were obtained experimentally, and the activation energy was calculated. The removal of digerma...

AbstractMethods for making platinum-based catalytic systems (Pt/C, PtRu/С) in an anode for a low-temperature hydrogen–air fuel cell with a Nafion membrane more tolerant to CO were suggested and implemented. A PtRuCo/C trimetallic catalyst was synthesized, and the influence of the modification of the binary catalyst with cobalt on the current charac...

AbstractThe concept of a new technology for producing hydrogen-containing gas from methane is presented. The process is performed in two separate vessels, a reactor and a regenerator, between which a microspherical catalyst containing active lattice oxygen continuously circulates. The following parameters of oxidative methane conversion were reache...

AbstractA method has been developed for synthesis of a composite coating based on polyaniline by introducing dispersed IR-pyrolyzed polyacrylonitrile, activated by alkaline treatment, into a polymer matrix. The coating is applied from a suspension in formic acid onto a graphite foil that has been previously subjected to anodic etching to improve th...

AbstractSynthesis of monomers is the key and most labor-consuming step in the development of highly selective membrane materials. Polyalkylenesiloxanes show promise for separation of vapors of organic components from gas mixtures. The paper considers two approaches to the synthesis of 1,1,3,3,5,5-hexamethyl-2-oxa-1,3,5-trisilacyclohexane, a monomer...

AbstractThe effect exerted on the chemical properties and structure of activated carbon by the mechanical treatment as a modification procedure was studied. Mechanochemical modification of carbon samples was performed in a roller–ring vibration mill for 5 to 30 min. Samples were studied by X-ray diffraction, IR spectroscopy, and low-temperature nit...
