Abstract: A feed system for a reactor, a reactor assembly comprising such a feed system, and a method of supplying a feed material to a reactor with a feed system are provided. The reactor may be a pyrolysis reactor, such as a fluidised bed pyrolysis reactor. A method of pyrolysing a feed material is also provided. The feed system may comprise a feed conduit extending from an inlet to an outlet, and may have a first section including the inlet and a second section including the outlet. The first section may accommodate an auger. The second section may comprise at least one plug forming zone in which feed material is compressed into a substantially gas-tight plug during operation. There may be a temperature regulator for controlling the temperature in the second section. The temperature regulator may comprise a cooling jacket.

Abstract: A reactor fluid supply system, a reactor system comprising such a fluid supply system, a method of supplying fluid into a reactor, and a method of operating a reactor system are provided. Preferably, the reactor system comprises a fluidised bed pyrolysis or combustion reactor and a fluid injector. The injector may comprise an internal flow passage extending from an inlet to an outlet, and have a first section including the inlet and a first portion of the passage and a second section including the outlet and a second portion of the passage. There may be a temperature regulator for controlling fluid temperature in the second section of the injector, the regulator comprising a cooling fluid jacket surrounding the second portion of the internal flow passage. The second section of the injector may be located inside the reactor so that the outlet of the injector is positioned in the fluidised bed of the reactor.
