“…The hydrogen is not applied in form of elemental hydrogen, but taken from the reactant molecule creating an unsaturated compound. This type of reaction has for example been discussed for the production of alkenes from alkanes [32,33]:…”

In the present paper the linear quasi static theory of viscoelasticity for Kelvin‐Voigt materials with double porosity is considered. The basic external boundary value problems (BVPs) of steady vibrations in this theory are formulated. The uniqueness and existence theorems for regular (classical) solutions of the BVPs are proved by using of the potential method (boundary integral equations method) and the theory of singular integral equations.

“…It is less extensively studied in comparison to the CO2-assisted dehydrogenation of ethane and propane. The catalysts reported for this reaction mainly consist of iron oxide [16], vanadium-magnesium oxide [17], V2O5 [18], LaBaSm oxide [19], and NiO [15]. There is still a challenge in enhancing the catalytic activity and selectivity.…”

Dehydrogenation of Isobutane with Carbon Dioxide over SBA-15-Supported Vanadium Oxide Catalysts

et al. 2016

A series of vanadia catalysts supported on SBA-15 (V/SBA) with a vanadia (V) content ranging from 1% to 11% were prepared by an incipient wetness method. Their catalytic behavior in the dehydrogenation of isobutane to isobutene with CO 2 was examined. The catalysts were characterized by N 2 adsorption, X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, and temperature-programmed reduction (TPR). It was found that these catalysts were effective for the dehydrogenation reaction, and the catalytic activity is correlated with the amount of dispersed vanadium species on the SBA-15 support. The 7% V/SBA catalyst shows the highest activity, which gives 40.8% isobutane conversion and 84.8% isobutene selectivity. The SBA-15-supported vanadia exhibits higher isobutane conversion and isobutene selectivity than the MCM-41-supported one.

“…These results concern mainly the dehydrogenation of ethane [1][2][3][4][5], propane [4,[6][7][8][9], butanes [4,9,10] and ethylbenzene [11][12][13][14][15] in the presence of CO 2 . The generally accepted role of carbon dioxide in the dehydrogenation of hydrocarbons is removal of hydrogen and suppression of coke deposition on the catalyst surface.…”

Effect of supports on catalytic activity of chromium oxide-based catalysts in the dehydrogenation of propane with CO2

Dehydrogenation of propane in the presence and absence of CO 2 over CrO x /SiO 2 and CrO x /Al 2 O 3 catalysts with Cr loading between 0.7-20.4 wt% was discussed. It was found that the nature of support strongly effects on the catalytic performance in the dehydrogenation with CO 2 . Over the CrO x /SiO 2 catalyst CO 2 enhance the propene yield, whereas over the CrO x /Al 2 O 3 catalyst the yield and selectivity of propene in the presence of CO 2 strongly decrease. The effect of steam on catalytic performance of the tested catalysts was also discussed.
