| 摘要 |
An autothermal reactor for producing high purity hydrogen from an organic feedstock, a source of oxygen and optionally water comprises a catalyst bed (13) for converting the feedstock into a hydrogen containing gas stream in association with a hydrogen diffusion membrane (9) which selectively separates hydrogen from the components of the gas stream. The hydrogen diffusion membrane preferably is in the form of a palladium based coil or spiral tube or a bundle of thin straight tubes or a palladium alloy supported on a porous ceramic substrate. The catalyst bed may be in the form of a granular bed of catalyst particles, a porous ceramic support material coated with catalyst, a porous ceramic foam coated with catalyst or a solid porous foam of catalyst. The catalyst bed and the hydrogen diffusion membrane preferably are located in the same reactor vessel and the catalyst bed is preferably positioned concentrically and coaxially around the hydrogen diffusion membrane. |
