中文摘要：
薄钯合成的膜被修改无电的 plating 方法与高氢流动在氧化铝支持和稠密的 Pd/-Al2O3 合成的膜上准备，为氢的好选择被获得。它在氮上为氢渗入和氢选择在一个单个煤气的浸透系统被测试。相应的膜的氢渗入象 2.45 ×一样高 10 ? 6mol · m ? 2 · s ? 1 · Pa ? 1 并且在 623K 和 0.1MPa 的压力差别的超过 700 的 H2/N2 选择。到 H2 浸透的合成的膜的主要抵抗躺在铝陶器的支持而非薄 Pd 层。
英文摘要：
Thin palladium composite membranes were prepared by modified electroless plating method on a-alumina supports and a dense Pd/α-Al2O3 composite membrane with high hydrogen flux, good selectivity for hydrogen was obtained. It was tested in a single gas permeation system for hydrogen permeance and hydrogen selectivity over mtrogen. The hydrogen permeance of the corresponding membrane was ashigh as 2.45×10^-6mol·m^-2·s^-1.Pa^-1 and H2/N2 selectivityover700 at 623K and a pressure difference of 0.1MPa. The-main resistance of the composite membrane to H2 permeation lies in the aluminum ceramic support rather than the thin Pd layer.
