A disk-shaped ceramic catalyst made by 3D printing (3DP) is used to reform syngas. We select two Al2O3 powders (α- andhigh-surface-area θ-Al2O3) and polymeric binders for preparing the 3DP feedstock. Catalyst stacked Al2O3 disks are made bykneading the polymers with ceramic powders and extruding to produce filaments, which are melted and used for 3D additivemanufacturing (AM). The processing parameters (sequence of addition, viscosity of the feedstock, etc.), the phasetransformation of the θ-powder, and catalytic properties of the made carrier are examined. The made alumina disks weredensified to a relative density (RD) of 40% −65%. Two porous disks were coated with catalyst NiO and CeO2, and used toreform syngas made from waste paper. The best case reforms the CH4 content in the syngas from 25.7% down to 0.15% orlower. The reformed gaseous fuel is suitable for solid oxide fuel cells (SOFCs). KCI Citation Count: 2
