STEAM REFORMER WITH INTERNAL HYDROGEN PURIFICATION

摘要

A steam reformer with internal hydrogen purification includes internal bulk hydrogen purification, internal hydrogen polishing to remove trace levels of carbon monoxide and carbon dioxide, an integrated combustion method utilizing waste gas to heat the reformer, efficient integration of heat transfer and a compact design. The steam reformer includes a concentric cylindrical architecture with the outermost shell (50) nesting an annular combustion region (60), and annular reforming region (62), and annular hydrogen transport region (54) and cylindrical polishing region (56).
