Catalytic Steam Reforming of Propane over Ni/LaAlO3 Catalysts: Influence of Preparation Methods and OSC on Activity and Stability

Abstract: To develop an efficient catalyst for steam reforming of propane, Ni/LaAlO 3 catalysts were prepared by deposition precipitation, impregnation, and solvo-thermal methods, and characterized by XRD, BET, H 2 -TPR, elemental analyses, and TEM. Ni/Al 2 O 3 and Ni/CeO 2 catalysts were also synthesized by the solvo-thermal method for comparison. The Ni/LaAlO 3 catalysts exhibited better catalytic performance than both Ni/Al 2 O 3 and Ni/CeO 2 catalysts, and activities with Ni/LaAlO 3 were found to be dependent upon t… Show more

“…Generally, these structural interactions may be of a textural nature affecting the physical properties of the Ni catalyst such as metal dispersion or metal crystal surface area [13][14][15] or they may be of an electronic nature, changing electronic densities of different catalyst components, and hence affecting the adsorption and chemical interactions of these components with different reaction intermediates [16,17]. Although these interactions may be established at the onset of the reaction [4,6,18,19], the nature of these interactions may change during time on stream.…”

“…Mn 2 O 3 and M‐doped catalysts (Mn 1.9 M 0.1 O 3– δ : M = Co, Cu, and Ni) were synthesized by coprecipitation method . Typically, to prepare 2 g of the Mn 1.9 Co 0.1 O 3– δ sample, 2.05 g of cobalt(II) nitrate hexahydrate (Co(NO 3 ) 2 ·6H 2 O, 291 g/mol) and 16.77 g of manganese(II) nitrate tetrahydrate (Mn(NO 3 ) 2 ·4H 2 O, 251.01 g/mol) salts were taken in aqueous form.…”

“…Формирование кристаллической структуры происходит при более высоких температурах, что может быть связано с полным удалением нитрат-анионов. катализаторов может также заключаться в том, что высокая лабильность кислорода в их структуре позволяет аккумулировать О 2 и регулировать его концентрацию в зоне катализа за счет эффекта накопительной емкости по кислороду [18], что обеспечивает устойчивую работу катализатора в кислородсодержащей среде при осуществлении процесса ТРМ [16].…”
