Reactor arrangement and method for decomposing objects consisting of plastic-based composite materials

A reactor arrangement for decomposing objects comprising plastic-based composite materials into individual constituents by performing solvolysis in at least one reactor chamber in which the objects are exposed to a solvent heated to a supercritical state, comprising:

• at least three pressure chambers positioned in series comprising a first load lock chamber, a reactor chamber adjoining the first load lock chamber, a second load lock chamber adjoining the reactor chamber which are connected together by actuatable partitions which are movable from an open position, in which two of the three adjacent pressure chambers are connected to each other, to a closed position, in which the two connected pressure chambers are fluidically, thermally and pressure isolatable from each other;
• the reactor chamber being thermally coupled to a heating system which is fluidically connectable by at least one first line to the first load lock chamber and is connected to a first pressurizable feed line through which solvent is fed into the reactor chamber;
• the second load lock chamber includes a second line which is connectable to the first load lock chamber;
• and
• means for transferring objects and a carrier for holding objects and objects being forced to transfer from one of the pressure chambers to an adjacent pressure chamber when one of the actuatable partitions is in an open position.
