Abstract

Fibrous Ni/Al2O3 catalysts prepared by one-step electrospinning have been recently developed for methane reforming. The purpose of this study is to investigate the merits of the fibrous catalysts via comparing with conventional monolithic Ni/Al2O3 catalysts prepared by impregnation. The fibrous catalysts exhibited the smaller and more uniform Ni nanoparticles, the stronger catalyst/support interaction and the higher catalyst loadings compared with supported spherical catalysts. In addition, fibrous catalysts demonstrate the faster mass transfer and the higher resistance to carbon deposition during methane partial oxidation, resulting in the higher syngas yields. Therefore, the fibrous catalysts have the advantages of the higher catalyst loading with the higher dispersion and the faster mass transfer for achieving the higher catalytic reaction rates over conventional impregnated catalysts.
