Reaction Kinetics of CO and CO₂ Methanation over Nickel [PDF]

Industrial & Engineering Chemistry Research, 2021
Methanation of both CO and CO2 with electrolysis-sourced hydrogen is a key step in power-to-gas technologies with nickel as the most prominent catalyst. Here, a detailed, thermodynamically consistent reaction mechanism for the methanation reactions of CO and CO$_{2}$ over Ni-based catalysts is presented.

Studies on the promotion of nickel—alumina coprecipitated catalysts: II. Lanthanum oxide [PDF]

, 1988
Two series of lanthanum promoted nickel—alumina catalysts have been prepared by coprecipitation of the metal nitrates, using potassium carbonate. The molar ratio between nickel and the sum of aluminium and lanthanum was kept constant at 2.5 or 9.0 within
