Catalyst support means for producing a fluid catalyst; a reduction basin that pretreats an active metal of the obtained fluid catalyst in a reducing atmosphere; a fluid bed reactor which is supplied with a reduction-treated fluid catalyst having undergone the reduction, for producing a nanocarbon material; and a moisture application basin for supplying a slight amount of moisture to a source gas to be supplied to the aforementioned fluid bed reactor are provided.

Apparatus and method for producing nanocarbon material

The present invention provides a catalyst for forming carbon nanotubes that improves a yield at the time of manufacturing carbon nanotubes and enables continuous mass production of carbon nanotubes with high purity. The catalyst for forming carbon nanotubes of the present invention includes a carrier that includes MgO and a metal catalyst that is supported by the carrier, and the concentration of the MgO in the carrier is set equal to 99 mass % or higher.

Catalyst for forming carbon nanotubes

A flue gas desulfurization apparatus includes at least one activated carbon fiber boardprovided in a catalyst unit, the board being formed by alternatingly juxtaposing one or more plate-like activated carbon fiber sheets and one or more corrugated activated carbon fiber sheets so as to provide vertically extending conduits, wherein water for producing sulfuric acid is supplied, through a capillary phenomenon, to the activated carbon fiber boardprovided in the catalyst unit. The flue gas desulfurization apparatus attains removal of sulfur oxides (SO) by adding a minimum required amount of water to the activated carbon fiber boardso as to attain uniform water distribution and can reduce the amount of water required for removing sulfur oxides (SO).

An apparatus for regenerating an adsorbent includes an electrolytic cell filled with an electrolyte and an electrode unit that includes a first electrode made from the adsorbent in which a substance is adsorbed and a second electrode. The first electrode and the second electrode are soaked in the electrolyte. The apparatus also includes a power source that supplies a voltage applied between the first electrode and the second electrode.

Method of and apparatus for regenerating adsorbent

A desulfurization apparatus for desulfurizing a flue gas containing sulfur oxides through contact with a porous carbon material. The carbon material, which is provided in a desulfurization tower, is at least one species selected from activated carbon and activated carbon fiber. The apparatus contains an NO-gas-feeding apparatus for feeding NOgas into the desulfurization tower. Within the desulfurization tower, a showering mechanism is provided at the top, the showering mechanism adjusting water content of the flue gas in the desulfurization tower to that corresponding to saturation with water vapor or higher at the treatment temperature.
