Abstract
Preparation of ZnO absorbents by 3D additive manufacturing (AM) for the adsorption of H2S in syngas fuel is conducted. ZnO feedstock for 3D AM was extruded to produce pyramid catalytic ceramic support (the absorbent) with a fracture strength of 5.7-9.1 MPa. The pore size of the supports showed bimodal distributions, which could impregnate Ni/CeO2 catalyst. The desulfurization effect of the catalyst/absorbent were investigated on simultaneously reforming of CH4 to H2 at 800°C. After reforming by the catalysts, the concentrations of H2S of 38.5 ppm in the raw syngas were reduced to a level of 0.9 ppm.
