STEAM REFORMING FUEL PROCESSOR

摘要

A steam reformer (200) includes a hydrogen producing region (36), in which a mixed gas stream (20) containing hydrogen gas and other gases is produced from vaporized water and a carbon containing feedstock (16'). The steam reformer further includes a separation region (22), in which the mixed gas stream (20) is separated into a hydrogen-rich stream (24) and a byproduct stream (26) and a polishing region (48), in which the hydrogen-rich stream is further purified and hydrogen product stream (14) is produced. In some embodiments, the steam reformer(200) is a vertically oriented fuel processor including an external metal or sealed ceramic shell, and the separation region (22) includes at least one hydrogen-selective membrane (46).
