The role of aluminum in the formation of Ni–Al–Co-containing porous ceramic converters with high activity in dry and steam reforming of methane and ethanol

Production of styrene by dehydrogenation of ethylbenzene on a [Re, W]/γ-Al2O3 (K, Ce)/α-Al2O3 porous ceramic catalytic converter

“…The effectiveness of the method presented in this paper is confirmed by previous studies on the high-speed production of hydrogen-containing gas in the processes of carbon dioxide, steam and mixed reforming of raw materials of fossil, synthetic and biological origin, such as methane, dimethyl ether and fermentation products [13][14][15], and in experiments on dehydrogenation of propane, butylene and isoamylene fractions to propylene, 1,3-butadiene and isoprene, respectively [16,17]. Another important factor that allows improvement in industrial technologies of basic organic synthesis is the prospect of using a catalytic converter as a replicable element of a new type of cassette reactors, which greatly simplifies the stages of loading and unloading of large volumes of catalysts, and also significantly increases the safety of the process.…”

Dry Reforming of Ethanol and Glycerol: Mini-Review

“…To optimize the performance of Ni based catalysts, promoters such as La and Ce were also incorporated [11,19,29]. The advanced redox properties of Ce resulted in great benefits for a Ce-Ni/Al 2 O 3 tested in the dry reforming of ethanol.…”

“…Similar to Ce promoted catalyst, amorphous carbon dominated on the surface of used La-Ni/Al 2 O 3 catalyst. This is may be due to the enhanced basicity of the promoted catalysts and the multiple oxidation states of La, which can provide a shortcut of coke conversion by redox reactions (Equations (29) and (30)).…”

Steam Reforming of n-Butane in Membrane Reactor with Industrial Nickel Catalyst and Foil Made of Pd-Ru Alloy

“…Under optimal conditions, ethane conversion was 70%, and ethylene formation selectivity was 95-98%. The studies [24,25] reported the high efficiency of carbon dioxide and steam reforming of methane, ethanol, and model mixtures of fermentation products into synthesis gas and hydrogen on membrane-catalytic systems, which are porous ceramic carrier membranes obtained by the method of self-propagating high-temperature synthesis and modified nanoscale metal complex components. In these systems, the processes of dry and steam reforming of organic substrates proceed much more intensively than in a traditional reactor with a fixed catalyst bed, which is due to improved mass and heat transfer.…”
