“…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.…”

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.

“…The utilization of C4 in chemical industry was mainly olefins, and C4 alkanes were primarily used as fuel. Isobutane was one of the main components of C4 alkanes which is often used for alkylation reaction to produce high octane number gasoline [7,8], and dehydrogenation to produce isobutene [9][10][11].…”

The CrHZSM-5 catalysts with trace amount of Cr were firstly used for catalytic cracking of isobutane, and the effect of Crloading on the catalytic performances of CrHZSM-5 catalysts for the cracking of isobutane was also studied. The results suggested that when the loading of Cr in the CrHZSM-5 catalysts was less than 0.038 mmol/g Cr, especially at Cr loading of 0.004 mmol/g, both the reactivity of isobutane cracking and the selectivity to light olefins of CrHZSM-5 samples were greatly enhanced compared with the unpromoted HZSM-5, and very high yields of olefins(C 2 +C 3 ) and ethylene were obtained. For instance, the yield of olefins(C 2 +C 3 ) and ethylene reached 56.1% and 30.8%, respectively, at 625°C when 0.004 mmol/g Cr was loaded on HZSM-5 sample.

“…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

2005

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.
