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

Included are a nano-carbon material production unit for producing a nano-carbon material using a fluidized catalyst formed by granulating a carrier supporting an active component, an acid treatment unit for dissolving and separating a catalyst by an acid solution by feeding a catalyst-containing nano-carbon material into the acid solution, and a pH adjustment unit, which is an anti-agglomeration treatment unit, provided on a downstream side of the acid treatment unit, for performing an anti-agglomeration treatment to prevent agglomeration among nano-carbons due to repulsion caused by dissociation among oxygen-containing functional groups added to the nano-carbon material.

Nano-carbon material production apparatus and method

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).
