HYDROGEN SEPARATION SYSTEM USING 5A GROUP METALLIC HYDROGEN SEPARATION MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen separation system providing a hydrogen recovery higher than in conventional reformers, by using both a Pd-based alloy hydrogen separation membrane and a 5A group metal alloy hydrogen separation membrane. SOLUTION: In the hydrogen separation system, the hydrogen separation membrane is disposed on the outer peripheral face of a support body consisting of a casing-like or a cylindrical porous support body or a support body consisting of a perforated plate serving for supporting the hydrogen separation membrane, and a plurality of hydrogen separation reformers formed by arranging a reforming catalyst layer are serially arranged on the outer periphery of the hydrogen separation membrane. The hydrogen separation membrane uses the Pd-based alloy hydrogen separation membrane on the upstream of the treating object gas, and the 5A group metal alloy hydrogen separation membrane on the downstream of the treating object gas.
