Improvements in and relating to reactor fluid supply systems

A reactor system for pyrolysis of a carbonaceous feed material, comprising a fluidised bed reactor and at least one injector for supplying fluid into the fluidised bed reactor, wherein:

• the at least one injector comprises an internal flow passage extending from an inlet to an outlet, the at least one injector having a first section including the inlet and a first portion of the internal flow passage, and a second section including the outlet and a second portion of the internal flow passage;
• the at least one injector additionally comprises a temperature regulator for controlling fluid temperature in at least the second section of the injector, wherein the temperature regulator comprises a cooling jacket configured to receive a cooling fluid, and wherein the cooling jacket extends along and surrounds the second portion of the internal flow passage;
• the fluidised bed reactor contains a fluidised bed zone configured to accommodate a fluidised bed when the reactor system is in use;
• and
• the second section of the at least one injector is located inside the reactor and extends into the fluidised bed zone so that the outlet of the injector is positioned in the fluidised bed zone.
