摘要： PROBLEM TO BE SOLVED: To suppress the deposition of carbon on the upstream side of a catalyst layer in a reformer, to consist essentially of butane gas in a hydrocarbon gas and to prevent the reliquefaction of butane gas even when outside temp. is low by providing a hydrogen adding means for adding gaseous hydrogen to hydrocarbon gas at the pre-stage from compression. SOLUTION: In an adjusting process of a gaseous starting material, gaseous hydrogen (H2 ) and butane gas (C4 H10 ) desulfurized in a time as short as possible are mixed in a volume ratio (gaseous hydrogen)/(butane gas) of a little over 4/5 and are supplied to a compressor 4. Gaseous hydrogen for producing the mixture is obtained by taking out a part of a gaseous hydrogen product from a gaseous hydrogen product taking out port 50 provided in the final process of a hydrogen generation device through a branched pipe 52 and a flow control valve 54, which are the gaseous hydrogen adding means. The branched pipe 52 is connected at the mid-way of a butane gas feed pipe 2 for supplying butane gas to the compressor 4.

摘要： PROBLEM TO BE SOLVED: To enable keeping of the temperature of an object fluid discharged from a heat exchanger constant regardless of the flow rate of the object fluid by providing a heat transfer area altering means to allow altering of a contact area between a heat exchanger tube and a heat medium. SOLUTION: An object fluid passing through a heat exchanger tube 80b undergoes a heat exchange with water in a heat medium container 80a. Drain ports 80d, 80d' and 80d" and the heat exchanger tube 80b makes up a heat transfer area altering means in cooperation to allow altering of a contact area of the heat exchanger tube 80b with water. In other words, when the target production quantity of hydrogen is the maximum thereof and the flow rate of a mixture of H, and Co leaving a reformer 100 is high, it is necessary to set the heat exchange capacity of a heat exchanger 80 to the maximum. Hence, the drain port 80d of the maximum level alone is opened while the drain ports 80d' and 80d" of the medium and minimum levels respectively are closed. Thus, an overflow occurs only at the drain port 80d to maximize the amount of water within the heat medium container 80a thereby allowing the setting of the heat transfer area of the heat transfer tube 80b with the water to the maximum value.
