Methanation of carbon dioxide: preparation of Ni/MgO catalysts and their performance

A novel W-doped Ni-Mg mixed oxide catalyst for CO2 methanation

“…Nevertheless, the large-scale application of these catalysts has been limited by their high cost. As an alternative solution, non-noble transition metal catalysts (e.g., Ni, Co) have attracted increasing attention for their comparable methanation activity with highly improved cost-efficiency [13][14][15][16].…”

“…However, the conventional metal oxides remain as the most promising support to optimize Ni-based catalysts for CO 2 methanation because of their high thermal stability and low cost [18]. Among those, MgO shows the potential because the strong interaction between Ni species and MgO favors the formation of highly dispersed small Ni particles, which contributes to the great enhancement of CO 2 methanation activities [13,16,19,20]. Further modifications of the surface properties can be achieved by controlling the formation of 'ideal' Ni-Mg solid solution [21,22].…”

Catalytic conversion of isopropanol over NiO/MgO system doped with Li2O

“…Magnesium oxide has been directly used as catalytic support [4,5] and as basic catalyst [6] in such reactions as aldolic condensation, isomerization of double bonds [5] and oxidative methylation of acetonitrile [7,8]. NiO/MgO is a catalyst or a catalyst precursor, used for steam reforming [9,10], methanation of CO and CO 2 [11,12] and N 2 O decomposition [13,14]. The NiO/MgO system constitutes ideal solid solutions over the whole molar fraction range having unusual catalytic properties [9,15,16].…”

Numerische Simulationen der katalytischen Methanisierung von CO2 in einem pseudo‐homogenen Strömungsrohr

“…Katalysatoren wie Ni [1], Ru [2], Rh [3], Pd [4], Fe [5] und Co [6] wurden verwendet, während Al 2 O 3 [7], SiO 2 [8], ZrO 2 [9], CeO 2 [10], La 2 O 3 [11], MgO [12], TiO 2 [13], Kohlenstoffmaterialien [14] und Zeolithe [15] als Katalysatorenträger eingesetzt wurden.…”
