A method which can efficiently produce ammonia at low temperature and low pressure and which can respond flexibly to an unsteady electrical power supply condition. In addition, a catalyst which is excellent in activity for synthesizing ammonia and which is used in a method for efficiently producing ammonia without regard to supply condition and supply location of electrical power. The method is characterized in that a reactor for synthesizing ammonia is used, and the reactor has a pair of electrodes, a voltage applying means for applying voltage between the electrodes, a catalyst between the electrodes, a raw material gas inlet port, and an ammonia-containing gas discharge port, and including introducing at least nitrogen and hydrogen as a raw material gas into the reactor for synthesizing ammonia, and applying a voltage to the electrodes of the reactor for synthesizing ammonia, wherein electrical discharge does not occur by the voltage.

Ammonia synthesis method and catalyst for ammonia synthesis

To improve a performance of a semiconductor device having a capacitance element. An MIM type capacitance element, an electrode of which is formed with comb-shaped metal patterns composed of the wirings, is formed over a semiconductor substrate. A conductor pattern, which is a dummy gate pattern for preventing dishing in a CMP process, and an active region, which is a dummy active region, are disposed below the capacitance element, and these are coupled to shielding metal patterns composed of the wirings and then connected to a fixed potential. Then, the conductor pattern and the active region are disposed so as not to overlap the comb-shaped metal patterns in the wirings in a planar manner.

A reforming catalyst () induces an isomerization reforming reaction and a decomposition reforming reaction of a gasoline fuel. Injectors () supply an isomerized fuel generated by the isomerization reforming reaction and a decomposed fuel generated by the decomposition reforming reaction respectively to the internal combustion engine (). The ratio of the isomerization reforming reaction and the decomposition reforming reaction depends on a catalyst temperature, and can be altered arbitrarily by controlling an air supply amount to the catalyst () via an air amount regulating valve () and a fuel supply amount to the catalyst () via a fuel injector () and thereby controlling the catalyst temperature.
