Abstract
Reactor for recovery or recycling of hydrocarbon products from hydrocarbon-containing material by decomposing and gasifying the material in a reactor housing, comprising a gas/particle separator device arranged to separate solid particles accompanying the gas and to return these particles directly to the reactor housing in the opposite direction to axially flowing gasified hydrocarbon products, and/or comprising a rotor shaft with axially running channels which are in flow communication with a coolant, and/or comprising a radial play formed between the periphery of a rotor and the inside of the reactor housing and amounting to at least 3 cm and at most 6 cm.

A reactor for recovering or recycling of hydrocarbon products from hydrocarbon-containing materials, comprising a cylindrical reactor housing extending axially between a rear, first end wall and a front, second end wall, a rotor rotatably arranged in the reactor housing and driven in rotation by means of a motor and a rotor shaft coaxially aligned with the reactor housing, the rotor shaft extending through the rear end wall into the reactor housing to which process material is fed radially or axially via an inlet to the reactor housing, gasified hydrocarbon products are discharged axially via a reactor gas outlet opening out centrally in the front end wall, and residual solid process material is discharged via a residual material outlet opening out peripherally in the reactor housing, wherein characterized in that at least a portion of the rotor shaft between the motor and the rotor is formed with channels running in the longitudinal direction of the rotor shaft, said channels being in flow communication with a coolant.
A reactor for recovery or recycling of hydrocarbon products from hydrocarbon-containing materials, comprising a cylindrical reactor housing extending axially between a rear, first end wall and a front, second end wall, a rotor rotatably arranged in the reactor housing and driven in rotation by means of a motor and a rotor shaft coaxially aligned with the reactor housing, the rotor shaft extending through the rear end wall into the reactor housing to which process material is fed radially or axially via an inlet to the reactor housing, gasified hydrocarbon products are discharged axially via a reactor gas outlet opening out centrally in the front end wall, and residual solid process material is discharged via a residual outlet opening out peripherally in the reactor housing, wherein between the periphery of the rotor and the inside of the reactor housing there is formed a radial play of 2 to 8 cm.
A method for recovering or recycling of hydrocarbon products from hydrocarbon-containing materials using a reactor for recovery or recycling of hydrocarbon products from hydrocarbon-containing materials, comprising a cylindrical reactor housing extending axially between a rear, first end wall and a front, second end wall, a rotor rotatably arranged in the reactor housing and driven in rotation by means of a motor and a rotor shaft coaxially aligned with the reactor housing, the rotor shaft extending through the rear end wall into the reactor housing to which process material is fed radially or axially via an inlet to the reactor housing, gasified hydrocarbon products are discharged axially via a reactor gas outlet opening out centrally in the front end wall, and residual solid process material is discharged via a residual outlet opening out peripherally in the reactor housing, wherein between the periphery of the rotor and the inside of the reactor housing there is formed a radial play of 2 to 8 cm,
- wherein said method comprise:
- generating and maintaining an agitated layer of non-fluidized finely ground material surrounding the reactor rotor, said layer having a radial extension of at least 2 to 8 cm between the rotor and the inside of the reactor housing.
