More Information
Summary:A hydrogen producing reactor is disclosed. The hydrogen producing reactor has a reaction chamber containing a catalyst bed adapted to produce reaction products con-taining hydrogen from a hydrogen-producing feedstock. The reaction chamber also in-cludes a hydrogen-selective, hydrogen-permeable gas separation module adapted to re-ceive the reaction products from the catalyst bed and to separate a product stream con-taining hydrogen from the reaction products. The gas separation module comprises a porous substrate, an intermediate porous layer located at the porous substrate, and a hy-drogen-selective membrane overlying the intermediate layer. The intermediate porous layer comprises a powder having a Tamman temperature higher than the Tamman tem-perature of the porous substrate. A steam reforming process is also disclosed using the disclosed reactor.
