| 摘要 |
The invention pertains to an installation comprising a reforming reactor (12) supplied with a vaporized and superheated methanol-water mixture, a device for heating the liquid methanol-water mixture by heat exchange (5) with the reformed gaseous mixture (56), a device for vaporizing and superheating the heated mixture by heat exchange (23) with a heat-carrying fluid (51), a device for effecting the reaction of the vaporized methanol-water mixture by heat exchange (28-29) also with the heat-carrying fluid (31-32), a separator (75) for separating the water from the reformed mixture by cooling and partial condensation (61-63-64), and a device for producing pure hydrogen which also produces residual combustibles, and a device (15) for heating the heat-carrying fluid (31-32) by combustion (15), in particular of the residual combustibles. The heat exchangers and the device for heating the heat-carrying fluid are all comprised by double coaxial tubing coil-type exchangers disposed about the inner cylindrical periphery of a same housing which forms both a combustion chamber (12) and a reforming reactor ( 28-31) (29-32).
