Selective oxidation of alcohols over foam-metal catalysts

Studies of CO2 absorption and effective interfacial area in a two-stage rotating packed bed with nickel foam packing

“…Since the metal foam materials have excellent physical properties, they are used as packing or catalyst support in the chemical processes in the last decade years [19][20][21]. The metal foam packing, which also has high specific surface area (a p ) and excellent mechanical strength, is very suitable for the gas-liquid or gas-liquid-solid flow in reactors [22][23][24][25]. In this work, a novel two-stage rotating packed bed with nickel foam packing (TSNF-RPB) was developed with the purpose of simplifying the combination of rotational packing and static rings in the rotor of a TSCC-RPB.…”

Evaluation of Foam Nickel for the Catalytic Partial Oxidation of Methane

“…However, very few studies have addressed the catalytic activity of the metallic foam itself. From those few studies, copper, copper alloys, nickel, nickel alloys [29,30,33], silver [33,34], and ferrous alloys [31] foams have all shown catalytic activity for the oxidation of hydrocarbons.…”

Alcohol selective oxidation over modified foam-silver catalysts

“…Our previous studies revealed that the selectivity of foam silver catalysts in alcohol oxidation accounted for 90-96 %, that exceeded the one of conventional crystalline silver catalyst by 2-5 % and commercial supported 40 wt.% Ag/pumice catalyst by 5-7 % [12][13][14][15][16]. This effect is caused by high gas permeability of the foam samples.…”

“…Thus, bulk foam silver and supported foam Ag/ceramics catalysts have physicochemical and catalytic properties exceeding the characteristics of the traditional crystalline silver and supported Ag/pumice catalysts under the same operating conditions [12][13][14][15][16]. Foam silver has higher gas permeability, mechanical strength, lower specific weight; it is not sintered during the high-temperature reaction due to its three-dimensional cellular structure.…”
