Silica-based hydrogen separation material and manufacturing method therefor, as well as hydrogen separation module and hydrogen production apparatus having the same |
摘要 |
An object of the present invention is to provide a hydrogen separation material resistant to thermal shock, excellent in hydrogen separation characteristic and applicable to a hydrogen separation membrane, etc. and a manufacturing method thereof, as well as a hydrogen separation module and a hydrogen production apparatus comprising the same.;In the hydrogen separation material, a silica glass membrane is formed on a porous support having a linear expansion coefficient of 2×10−6/K or less. The manufacturing method for the hydrogen separation material includes a porous support forming step of forming a porous support comprising porous silica glass and a silica glass membrane forming step of forming a silica glass membrane on the surface of the porous silica glass. The hydrogen separation module comprises the hydrogen separation material and a steam reforming catalyst. The hydrogen production apparatus comprises the hydrogen separation module. |
