    摘要: A method for improving thermal efficiency of steam production in a steam reforming based syngas plant is provided. In one embodiment, the method can include the steps of: preheating a hydrocarbon feed stream in a first heat exchanger from a first temperature to a second temperature; preheating the hydrocarbon feed stream in a second heat exchanger to a third temperature, wherein the third temperature is greater than the second temperature; introducing the hydrocarbon feed stream in the presence of steam to a steam methane reformer under conditions effective for producing a product stream comprising hydrogen, carbon oxides, and water vapor; and exchanging heat between the product stream and a boiler feed water stream in a third heat exchanger, wherein prior to exchanging heat with the product stream, the boiler feed water stream is used to provide the preheating to the hydrocarbon feed stream in the first heat exchanger.

    摘要: Provided is a transportation device which is capable of continuously travelling without being supplied with hydrogen from the outside. According to the present invention, a transportation device is provided with an ammonia storage means, a hydrogen production device, a fuel cell, a motor, a battery and a control unit. The hydrogen production device produces hydrogen by decomposing ammonia; and the fuel cell is supplied with hydrogen from the hydrogen production device and generates electric power. The motor operates by being supplied with some or all of the electric power generated by the fuel cell. The battery is supplied with some or all of the electric power generated by the fuel cell, and supplies electric power to the motor and the hydrogen production device.

    摘要: A compact fuel battery system is provided that has an integrated hydrogen generator. This fuel battery system 1 is provided with a hydrogen generator 10 and a fuel battery cell 20. The hydrogen generator 10 is provided with a plate-shape dielectric 2 having a raw material gas flow path surface 11 in which a raw material gas flow path 13 is formed. An electrode 3 faces the back surface 12 of the dielectric 2. A hydrogen separation membrane 5, which has a first surface 18 and the second surface 19, closes an opening of the raw material gas flow path 13. Furthermore, the hydrogen generator 10 is provided with a high-voltage power supply 6 which generates electric discharge between the hydrogen separation membrane 5 and the electrode 3. The fuel battery system is characterized in that the second surface 19 of the hydrogen separation membrane 5 of the hydrogen generator is arranged facing the fuel electrode 21 of the fuel battery cell 20.
