Mesoporous nickel (35 wt%)-M (5 wt%)-alumina xerogel (denoted as 35Ni5MAX) catalysts with different second metal (M = Fe, Zr, Ni, Y, and Mg) were prepared by a single-step sol-gel method for use in the methane production from carbon dioxide and hydrogen. In the carbon dioxide methanation reaction, yield for CH 4 decreased in the order of 35Ni5FeAXThis indicated that the catalytic performance was greatly influenced by the identity of second metal in the carbon dioxide methanation reaction. Experimental results revealed that CO dissociation energy and metal-support interaction of the catalyst played key roles in determining the catalytic performance of 35Ni5MAX catalysts in the reaction. Among the catalysts tested, 35Ni5FeAX catalyst, which retained the most optimal CO dissociation energy and the weakest metalsupport interaction, exhibited the best catalytic performance in terms of conversion of CO 2 and yield for CH 4 .

“…600°C). Nickel supported on alumina is the most commonly used catalyst for CO methanation due to its good http catalytic performance and relatively low price [4,5]. However, Ni/ c-Al 2 O 3 catalyst prepared by conventional methods, such as coprecipitation, impregnation, sol-gel and mechanical mixing, showed low activity at low-temperature, and deactivated easily at hightemperature [6].…”

“…Using a magnetic amorphous Ni alloy catalyst, recently, a novel MSB reactor was proved to intensify successfully the purification process of caprolactam 6,7 through effectively enhancing hydrogenation efficiency and reducing reactor volume and reaction temperature. However, the industrial application of MSB is restricted by the lack of appropriate magnetic catalysts for related reactions.…”

in Wiley InterScience (www.interscience.wiley.com).A novel magnetic microspherical catalyst support with enough mechanical strength was prepared through coating Al 2 O 3 on a magnetic core of NiFe 2 O 4 spinel ferrite using the oil drop method to synthesize magnetic Pd-supported catalyst for acetylene hydrogenation reaction. The synthesized core-shell composite Pd/Al 2 O 3 catalyst shows high surface area and pore volume as well as sufficient saturated magnetization property, characterized by powder X-ray diffraction, low-temperature N 2 adsorptiondesorption analysis, and magnetic measurements. Catalytic performance of this magnetic Pd/Al 2 O 3 catalyst was measured for acetylene hydrogenation reaction in a magnetically stabilized bed (MSB) reactor under different operation conditions. Under the optimal conditions of 353 K, 1.5 MPa and a gas hourly space velocity of 12,000 h 21 , C 2 H 2 conversion and C 2 H 4 selectivity approximated 100% and 84%, respectively, over this magnetic Pd/Al 2 O 3 catalyst in the MSB reactor, as a control over the commercial catalyst for hydrogenation reaction C 2 H 2 conversion and C 2 H 4 selectivity was near 37 and 64% under the similar conditions. Significant improvement of acetylene hydrogenation processes over this novel magnetic catalyst enlightens us a promising route to explore process intensification techniques through MSB.
