Abstract: The invention provides a carbonaceous feed pyrolysis apparatus including two or more hot particle fluidised beds, and material transfer means for the transfer of hot catalyst particles between two or more of the beds, wherein one or more of the 5 fluidised beds is a gasifier which contains a gasification zone and one or more of the fluidised beds is a pyrolysis reactor which contains a pyrolysis zone, so that the particles are recirculated and serve as an energy carrier to drive pyrolysis in the pyrolysis zone. The invention extends to a carbonaceous feed pyrolysis process using said apparatus.
