Title:
FUEL PROCESSING REACTOR WITH INTERNAL HEAT EXCHANGE FOR LOW PRESSURE GAS STREAM
Document Type and Number:
WIPO Patent Application WO2004090074
Kind Code:
A3
Abstract:
A compact fuel processing reactor (10) includes a housing (90) having an inlet (40) for receiving a process gas (20) and an outlet (50) for a directing a product gas out (30) of the housing. A catalyst bed (60) that includes discrete particles (70) of a refractory material is located within the housing for contacting the process gas. A coiled tubing heat exchanger (80) is at least partially disposed within the catalyst bed for cooling the catalyst bed. The coiled tubing (86) can comprise a smooth continuous outer surface in intimate contact with the discrete particles (70). The circulating cooling medium (82), (84) comprises water in liquid, gas or a mixture of liquid and gas phases. The discrete particles (70) in the catalyst bed are in intimate contact with at least a portion of the coiled tubing (86) to promote heat transfer from the catalyst bed to the coiled tubing. The heat exchanger (80) has less than about 25, preferably less than about 20, more preferably less than about 15, and still more preferably less than about 10 square meters of heat exchanging surface area per cubic meter of catalyst bed. The catalyst bed (60) can be a water gas shift, desulfurization or reforming bed. The reactor can include one or more additional catalyst beds arranged in series such that the housing encloses a shift catalyst bed as well as a desulfurization bed and/or a reforming bed. Methods of cooling a catalyst bed within a compact reactor and methods of manufacturing a compact reactor are also provided.
