摘要:
Provided is a power conversion system having a solid-oxide fuel cell capable of stably generating electricity from hydrogen generated by an organic hydride. The power conversion system includes a solid-oxide fuel cell, a reactor for producing hydrogen and a dehydrogenation product from an organic hydride by dehydrogenation reaction, and a heat engine for generating motive power. The power conversion system separates the hydrogen produced by the reactor, and supplies the hydrogen as fuel to the solid-oxide fuel cell. Exhaust heat of the heat engine is supplied to both the solid-oxide fuel cell and the reactor.

To allow hydrogen to be supplied to a dehydrogenation reaction unit for dehydrogenating an organic hydride by using a highly simple structure so that the activity of the dehydrogenation catalyst of the dehydrogenation reaction unit is prevented from being rapidly reduced. The hydrogen production system (1) comprises a first dehydrogenation reaction unit (3) for producing hydrogen by a dehydrogenation reaction of an organic hydride in presence of a first catalyst, and a second dehydrogenation reaction unit (4) for receiving a product of the first dehydrogenation reaction unit, and producing hydrogen by a dehydrogenation reaction of the organic hydride remaining in the product in presence of a second catalyst, wherein an amount of the first catalyst used in the first dehydrogenation reaction unit is equal to or less than an amount of the second catalyst used in the second dehydrogenation reaction unit, and an amount of hydrogen produced in the first dehydrogenation reaction unit is less than an amount of hydrogen produced in the second dehydrogenation reaction unit.

Provided are a carbon catalyst for hydrogen production having an excellent catalytic activity, a production method therefor, and a method of producing hydrogen using the catalyst. The carbon catalyst for hydrogen production is a carbon catalyst, which is obtained by carbonizing a raw material including an organic substance and a transition metal, the catalyst being used for hydrogen production by thermal decomposition of a hydrocarbon compound and/or an oxygen-containing organic compound. Further, the carbon catalyst for hydrogen production may be obtained by loading an alkaline earth metal on a carbonized material produced by the carbonization.
摘要:
A hydrogen production process and a reactor for dehydrogenation in which it is possible to mix hydrogen with a raw material for a dehydrogenation reaction easily and simply and suppress a reduction in the performance of a dehydrogenation reaction catalyst when hydrogen is produced by combining the dehydrogenation reaction of organic hydrides or the like with a hydrogen separation membrane. A flow-type reactor for dehydrogenation of an organic compound includes a hydrogen separation membrane selectively permeable to hydrogen; and a dehydrogenation catalyst for promoting a dehydrogenation reaction of an organic compound which can release hydrogen upon the dehydrogenation reaction, including: a reaction side area through which the organic compound can flow and which includes the dehydrogenation catalyst and a permeation side area which is separated from the reaction side area by the hydrogen separation membrane and through which hydrogen that has passed through the hydrogen separation membrane can flow.
摘要:
Processes for using a combination of carbon dioxide and oxygen in the dehydrogenation of hydrocarbons are provided. A hydrocarbon feedstock, carbon dioxide and oxygen are fed to an oxidative dehydrogenation reactor system containing one or more catalysts that promote dehydrogenation of the hydrocarbon feedstock to produce a dehydrogenated hydrocarbon product. The processes of the present invention may be used, for example, to produce styrene monomer by dehydrogenation of ethylbenzene using carbon dioxide and oxygen as oxidants.
摘要:
Recovery of dehydrogenation product must be done separately from supply of hydrogen fuel. However, there is a problem that it takes much time when dehydrogenation product recovery and fuel filling are done separately. A fuel filling/waste solution recovery apparatus includes measuring means to measure a volume of supplied fuel and a volume of recovered waste solution by measuring flow rates of solutions passing through a fuel filling nozzle and a recovery nozzle or piping, and a display which shows the volume of supplied fuel and the volume of recovered waste solution which are measured by the measuring means.
