Ni(II)-Al(III) layered double hydroxide as catalyst precursor for ethanol steam reforming: Activation treatments and kinetic studies

A Kinetic Study of Ethanol Steam Reforming Using a Nickel Based Catalyst

“…The reduced NiAl sample had a specific area of 100 m 2 /g and the mean size of the Ni metallic crystallites was estimated using Scherrer's equation, being close to 5 ± 1 nm. More details of synthesis and characterization of NiAl sample are given elsewhere [22].…”

Improved reversibility of color changes in electrochromic Ni–Al layered double hydroxide films in presence of electroactive anions

“…Net positive charges on the layers are balanced by exchangeable anions intercalated between the sheets [2][3][4][5]. LDHs have potential applications as catalysts and catalyst supports [6][7][8][9][10], anion exchangers and molecular containers [11][12][13], for use as electrical and optical functional materials [14][15][16][17][18] and as flame retardants and nanofillers [19][20][21][22][23]. LDHs containing nickel also are under consideration as alternative cathode materials for nickel batteries [24][25][26].…”

Energy and exergy analysis of an ethanol fueled solid oxide fuel cell power plant

“…After that, the liquid mixture is vaporized and preheated on devices HEX-1 and HEX-2 prior to the Reactor inlet. The endothermic steam reforming of the ethanol ( ∆H = +173.5 kJ/mol) is studied considering a packed bed reactor charged with a Ni/Al hydrotalcite catalyst [15][16] and among the various reaction patterns reported previously [14,[16][17] the Lagmuir-Hishelwood kinetic model reported in Arteaga et al [6,14] is used to describe a six step reaction scheme including the coke deposition on catalyst surface The mixture leaving the Reactor is then fed into a solid oxide fuel cell module where an air flux (21%O 2 , 79%N 2 ) is used as oxidant which is previously compressed and heated in a Compressor, HEX-3 and HEX-4. The SOFC model is used to study the process and to design various scenarios considering variations of the reformer operational parameters.…”
