1. A pyrolysis reaction system, the system comprising:
a pyrolysis chamber comprising a feed inlet, a gas inlet and a product outlet, wherein the pyrolysis chamber is configured i) to receive a pyrolysable organic feed and an inert gas via the feed inlet and gas inlet respectively, ii) to pyrolyse the organic feed at a pyrolysis temperature to produce a carbonaceous pyrolysis product and a pyrolysis gas, wherein the pyrolysis gas will combine with the inert gas in use to form a gas mixture having a pyrolysis chamber pressure in the pyrolysis chamber, and iii) to discharge the carbonaceous pyrolysis product via the product outlet;
a gas reactor configured to react the pyrolysis gas by combustion at a gas reaction temperature and a gas reactor pressure; and
a first partition defining a boundary between the pyrolysis chamber and the gas reactor, the first partition comprising a plurality of first apertures to provide fluid communication between the pyrolysis chamber and the gas reactor,
wherein the pyrolysis reaction system is operable with the gas reactor pressure less than the pyrolysis chamber pressure such that the gas mixture flows from the pyrolysis chamber to the gas reactor through the first apertures, thereby providing at least a portion of the pyrolysis gas for reaction in the gas reactor,
wherein the pyrolysis reaction system is configured to transfer heat by convection and/or conduction from the gas reactor to the pyrolysis chamber through the first partition when the gas reaction temperature is greater than the pyrolysis temperature in operation,
wherein the first partition is configured to exclude solids from the gas mixture flowing from the pyrolysis chamber to the gas reactor through the first apertures,
wherein the gas reactor comprises a port for introducing a gas containing oxygen and a duct for removing flue gas, wherein the gas reactor is configured such that in operation the pyrolysis gas reacts by combustion with the oxygen, and
wherein the gas reactor comprises an annulus surrounding the pyrolysis chamber and the port is configured to introduce the gas containing oxygen tangentially into the gas reactor such that a vortex flow around the pyrolysis chamber is produced in at least a part of the annulus.
