An analyzer includes a reforming unit which reforms fuel containing an organic compound which contains carbon and hydrogen into a reformed gas containing hydrogen, a flame ionization detector which is connected to the reforming unit, and detects an ion generated by combusting the reformed gas supplied from the reforming unit and a sample gas, or ionizing a sample gas by reaction with the reformed gas supplied from the reforming unit, and outputs an output signal representing the ionic amount, and an analysis controller which analyzes the output signal from the flame ionization detector, and provides data capable of identifying a component contained in the sample gas.

Analyzer

A processing apparatus capable of separating and recovering resins and metals, respectively, from an object being processed, which has resins and metals as its constituent, comprises a first gastight area (,), in which temperature and pressure are regulated so as to permit selective thermal decomposition of resins from the object (,) being processed, a second gastight area (,), which is partitioned from the first gastight area by an openable and closeable partition (,C) and in which temperature and pressure are regulated so as to permit selective vaporization of metals from the object, first recovering chamber (,) connected to the first gastight area for recovering gases produced by thermal decomposition of resins, and second recovering chamber (,) connected to the second gastight area for recovering vaporized metals.

Processing apparatus, processing system and processing method

Disclosed is a method of reclaiming a cathodic active material of lithium ion secondary batteries. The lithium ion secondary battery is broken and the casing and the content are separated to remove the casing from the content. The content is dissolved into a mineral acid to separate remaining non-dissolved content from the mineral acid to obtain a liquid containing the cathodic active material represented by the formula: LiMO,, where M is a transition metal element: cobalt, nickel and manganese. A lithium salt is added to the liquid, and the cathodic active material is recovered from the liquid in the form of a mixture of lithium compound and the transition metal compound, which is calcined and reclaimed into the cathodic active material.

Disclosed is a method and apparatus for pyrolytically decomposing waste plastic which may contain halogen-containing polymer such as PVC. The plastic is heated at 270&deg; to 350&deg; C., whereby a plasticizer contained in the plastic material is decomposed and vaporized, and a chlorine-containing polymer is dechlorinated to produce hydrogen chloride. The vaporized decomposition matter and the hydrogen chloride are removed from the plastic, and the vaporized decomposition matter is separated from the hydrogen chloride. Then isolated plastic is further heated to 450&deg; C. or higher to produce a pyrolysis product. Alternatively, the former heating step is divided into two steps of: heating at a temperature lower than 270&deg; C., whereby a plasticizer is decomposed; and heating to 270&deg; to 350&deg; C., whereby a chlorine-containing polymer contained in the plastic material is dechlorinated. Accordingly, the decomposition matter of plasticizer and hydrogen chloride are separately removed from the plastic.

Disclosed is a method of recovering lithium from a battery containing lithium such as a lithium ion secondary battery. The lithium-containing member of the battery is dissolved with an acidic liquid, and an alkaline material is added to the obtained lithium solution to transform a transition metal which may be dissolved in the lithium solution into a metal hydroxide precipitation, whereby the metal hydroxide precipitate is separated from the lithium solution. The lithium solution is then dried to obtain a solid containing the lithium, and the lithium is eluted from the solid with a non-aqueous solvent. Retrieving lithium from the lithium eluate is accomplished by use of a cation exchanger.

Disclosed is a method and an apparatus for pyrolytically decomposing waste plastic, e.g. PVC, to recover light fuel oil. The invention enables to prevent the product from contamination by halogen compounds. The plastic is first thermally decomposed in an atmosphere of a normal or reduced pressure to produce a primary decomposition product in the form of gas and a decomposition residue. The primary decomposition product is cooled at a first cooling temperature to separate the primary decomposition product into a relatively light fraction containing a desired light constituent and a relatively heavy fraction by condensation of the relatively heavy fraction, and the relatively heavy fraction is then thermally decomposed in an atmosphere pressurized at a predetermined pressure to produce a secondary decomposition product containing the desired light constituent in the form of gas. The relatively light fraction and the secondary decomposition product are cooled at a second cooling temperature to condense a fraction containing the desired light constituent. This method may be changed so that the first and second thermal decomposition steps are performed at the same high pressure in one vessel and the heavy fraction is circulated. Additionally, alkali treatment of time plastic to be decomposed or the decomposition gas, thermal pretreatment of the plastic and addition of water or catalyst to the plastic can be used. The decomposition apparatus which is so systematized that the decomposition can be continuously performed is shown.
