Abstract (en)
[origin: WO2022090079A1] The invention relates to a reactor arrangement and to a method for decomposing objects consisting of plastic-based composite materials into their individual constituents by way of a solvolysis using at least one reactor chamber in which the objects can be exposed to a solvent in the supercritical state. The invention is characterised in that at least three pressure chambers arranged in series, a first load lock chamber, a reactor chamber adjoining same, and a second load lock chamber adjoining the latter, are provided and are each connected to each other via an actuatable partition means which can be moved in each case from an open position, in which two of the mutually adjacent pressure chambers are connected to each another, to a closed position, in which two of the mutually adjacent pressure chambers are fluidically, thermally and pressure-specifically isolated from each other. The reactor chamber is thermally coupled to a heating system and can be directly or indirectly fluidically connected via at least one first line to the first load lock chamber and can be connected to a first pressurisable feed line, via which solvent can be fed into the reactor chamber. The second load lock chamber has a second line, which can be connected directly or indirectly to the first load lock chamber. A means is also provided which can transfer the objects or a carrier holding the objects from one pressure chamber to the adjacent pressure chamber in a force-assisted manner when the partition means is moved into the open position.
