Abstract

The present invention relates to a rotor for a pyrolysis centrifuge reactor, said rotor comprising a rotor body having a longitudinal center axis, and at least one pivotally mounted blade being adapted to pivot around a pivot axis under rotation of the rotor body around the longitudinal center axis. Moreover, the present invention relates to a pyrolysis centrifuge reactor applying such a rotor.

First claim

The invention claimed is:

1. A pyrolysis centrifuge reactor comprising:
a reactor housing having a centre axis, the reactor housing comprising tracks formed in or on an inner surface of the reactor housing in order to lead a solid feed from an inlet to an outlet, and
a pyrolysis rotor comprising a cylindrically shaped rotor body having a longitudinal centre axis that essentially coincides with the centre axis, and at least one pivotally mounted blade being adapted to pivot around a pivot axis under rotation of the rotor body around the longitudinal centre axis, wherein the at least one pivotally mounted blade is positioned in a recess formed in a peripheral surface of the cylindrically shaped rotor body.

2. A pyrolysis centrifuge reactor according to claim 1 , further comprising a reaction vessel formed between the peripheral surface of the rotor body and the inner surface of the reactor housing.

3. A pyrolysis centrifuge reactor according to claim 2 , wherein the at least one pivotally mounted blade is adapted to pivot between an inner position given by a shape of the recesses in the rotor body and an outer surface given by the inner surface of the reactor housing.

4. A pyrolysis centrifuge reactor according to claim 1 , wherein the pivot axis is essentially parallel to the longitudinal centre axis.

5. A pyrolysis centrifuge reactor according to claim 1 , wherein the pyrolysis rotor comprises a plurality of pivotally mounted blades.

6. A pyrolysis centrifuge reactor according to claim 5 , wherein each of the plurality of pivotally mounted blades is adapted to pivot around an associated pivot axis under rotation of the rotor body.

7. A pyrolysis centrifuge reactor according to claim 5 , wherein the plurality of pivotally mounted blades are positioned in respective recesses formed in the peripheral surface of the cylindrically shaped rotor body.

8. A pyrolysis centrifuge reactor according to claim 5 , wherein an overall length of the plurality of pivotally mounted blades essentially equals a length of the rotor body.

9. A pyrolysis centrifuge reactor according to claim 1 , further comprising a rotor axle, said rotor axle coinciding with the longitudinal centre axis of the rotor body.

10. A method of using a pyrolysis centrifuge reactor according to claim 1 , wherein the rotor rotates with a speed of rotation being less than 6000 rpm.
