| 概要 |
Porous ceramic catalysts were fabricated by using hexaaluminate (BaMnAl11O19-alpha) as a base material. The two-stage sintering of hexaaluminate powders produced large macropores (>10,μm), being effec...tive in increasing gas permeability. The gas permeability of two-stage sintered hexaaluminate increased with elevating the first-stage sintering temperature and with lowering the second-stage sintering temperature. Calcination of alkoxide-derived gel produced the bulk sample, which showed the gas permeabilities higher than those of the two-stage sintering sample. Thermal decomposition of polyethylene dispersed in gel appears to form macropores (>10,μm) in a heating process. The porous ceramic catalyst thus obtained showed the high catalytic activity for methane combustion.続きを見る
