  • Patent number: 9696290
    Abstract: The interior of a fractionating tool for fractionating dioxins is packed with a purification layer and an adsorption layer. The adsorption layer includes a first adsorption layer including an activated carbon-containing silica gel layer and a graphite-containing silica gel layer, and a second adsorption layer including an alumina layer. When a solution of dioxins is injected into the purification layer and is supplied with an aliphatic hydrocarbon solvent, the solvent dissolves dioxins in the solution of dioxins and passes through the purification layer and the adsorption layer. In this process, non-ortho PCBs, PCDDs and PCDFs among dioxins are adsorbed to the first adsorption layer, and mono-ortho PCBs among dioxins are adsorbed to the second adsorption layer. As a result, dioxins are fractionated into a group including non-ortho PCBs, PCDDs and PCDFs, and mono-ortho PCBs.

    Abstract: A method for manufacturing Cu—Sn coexisting steel produces a good quality surface even after hot rolling. The steel is manufactured by continuous casting a molten steel that contains C: 0.04 to 0.20%, Si: 0.05 to 1.00%, Mn: 0.20 to 2.50%, P: no more than 0.05%, S: no more than 0.02%, Cu: 0.20 to 1.50%, Sn: 0.06 to 0.50%, Al: 0.06 to 1.00% and Ni: 0.05 to 1.00% by mass, and Fe and impurities as the remainder. The composition of the molten steel is defined as [Al]/(3[Si]+[Mn])?0.050, [Ni]/([Cu]+5[Sn])?0.10 and [Al]/[Ni]?0.20 if the content of an element X in the molten steel is represented as [X], an internal oxidation layer is formed in a process of cooling a slab, and Al2O3 is contained by the internal oxidation layer.

  • Publication number: 20160003784
    Abstract: A solute trapping column including two trapping agent layers has a first branched pathway extending from an upper part of a main body part thereof, and a second branched pathway extending from between two trapping agent layers, and with its upper part a purification column is connected. By injection of solution of dioxins and supply of solvent into the purification column, dioxins are trapped by the trapping agent layers. An extraction solvent supplied from the lower end side of the solute trapping column while keeping both the purification column and the first branched pathway blocked extracts the dioxins trapped by the second trapping agent layer and flows into the second branched pathway. An extraction solvent supplied in a similar manner while keeping both the purification column and the second branched pathway blocked extracts the dioxins trapped by the first trapping agent layer and flows into the first branched pathway.
