Injector, reactor, apparatus and process for pyrolysis of polymeric material

A pyrolysis injector for a pyrolysis reactor comprising:

• a feeder unit with a particulate polymeric material inlet and an oil inlet, wherein said particulate polymeric material inlet and said oil inlet lead to an oil retention reservoir arranged for mixing said particulate polymeric material and oil into a mixture of oil-wet particulate polymeric material, and with one or more feeding augers arranged in a feeder gutter portion of said oil retention reservoir, said oil retention reservoir configured to retain a volume of oil having a fluid surface at a level above the feed gutter portion
• said feeder gutter portion leading to a narrowing pipe portion about an end portion of said one or more feeding augers arranged for compacting said oil-wet particulate polymeric material for forming a compacted oil-wet particulate polymeric material,
• said narrowing pipe portion leading to a compacting pipe arranged for feeding said compacted oil-wet particulate polymeric material to the pyrolysis reactor through an injector-reactor inlet,
• one or more first heating elements arranged for heating said oil retention reservoir with said mixture of oil-wet particulate polymeric material present therein, and for boiling off one or both of water and chemicals,
• one or more second heating elements arranged on said compacting pipe with said compacted oil-wet particulate polymeric material and arranged for pre-heating said compacted oil-wet particulate polymeric material before injection to said pyrolysis reactor through the injector-reactor inlet, and
• wherein said oil inlet is arranged for receiving a part of an intermediary condensed pyrolysis fluid in a condensed liquid state back to said oil retention reservoir.
