| description | To provide a packed bed capable of suppressing the outflow of fine powder without using an adhesive, and retaining catalytic activity.SOLUTION: A packed bed is formed from a mixture of porous particles and fine powder, where (1) the porous particles have a skeleton body, the skeleton body has a through hole, a most frequent pore diameter in a pore diameter distribution of the through hole is 0.1 μm or more and 100 μm or less, and a particle size of the porous particle is 20 μm or more and 3,000 μm or less; and (2) an average primary particle diameter of the fine powder is 1 nm or more, and 80% or less of the most frequent pore diameter of the pore diameter distribution of the through hole.SELECTED DRAWING: None
【課題】接着剤を使用せずに微粉末の流出を抑制し、且つ、触媒活性を維持することができる充填層を提供する。【解決手段】多孔性粒子と微粉末との混合物から形成されている充填層であって、（１）該多孔性粒子は骨格体を有し、該骨格体が貫通孔を有し、該貫通孔の孔径分布の最頻孔径が０．１μｍ以上１００μｍ以下であり、且つ、該多孔体粒子の粒度が２０μｍ以上３０００μｍ以下であり、（２）該微粉末の平均一次粒子径が１ｎｍ以上であり、且つ、該貫通孔の孔径分布の最頻孔径の８０％以下である、ことを特徴とする充填層。【選択図】なし |
