The Binder Jetting 3D printing technique was used to fabricate spherical Ni-Al CO2 methanation catalysts from co-precipitated catalyst precursor powder.Catalysts with different nickel loadings were prepared by varying the molar Ni/Al ratio(1/1,2/1,3/1,5/1)during precipitation or the amount of admixed precursor powder(10,20,30 wt.%)for printing.XRD and TG analysis revealed phase composition and reducibiliry characteristics analogous to conventionally prepared Ni-Al catalysts.TEM displayed nickel particle sizes as small as 3.9 run with a Ni dispersion of up to 13.4 % determined by H2 chemisorption.Moreover,meso-and macroporous catalyst pellets were generated with a specific surface area of up to 192 m~2/gcat-The catalysts NiAl11-20,NiA121-20 and NiA151-20 were exemplarily tested in a single pellet string reactor where CO2 conversions of up to 99 % and a high selectivity towards CH4 was observed at p_(tot)= 9 bar upon reaching thermodynamic equilibrium.
