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.

Abstract: A reactor system for pyrolysis of carbonaceous waste, a method of treating waste comprising carbonaceous waste by pyrolysis in the reactor system, and uses of particulate material in the reactor system and/or method, are provided. The reactor system comprises a fluidised bed pyrolysis reactor. The fluidised bed pyrolysis reactor comprises a shell defining a heating chamber, the heating chamber having a fluidised bed zone configured to contain a fluidised bed of particulate material comprising particulate material susceptible to inductive heating. The reactor system also comprises a pyrolysis induction heater assembly comprising an induction emitter configured to inductively heat the particulate material. The shell of the reactor is made from an inductively inert material.
