Abstract: A carbonaceous feed pyrolysis apparatus is provided including two or more hot particle fluidised beds, one of which contains a combustion zone, and one or more positive displacement apparatus for the transfer of hot particles beds. Also provided is a bio-oil production process including two or more fluidised beds, a first combustion zone carried out in one or more combustion fluidised beds in which a particulate material is fluidised and heated, and a second pyrolysis zone carried out in one or more pyrolysis fluidised beds in which hot particles heated in the combustion zone are used for pyrolysis of bio-mass, the combustion zone being operated at or about atmospheric pressure at a temperature of from 400° C. to 1100° C., and the pyrolysis zone being operated at a pressure of from atmospheric to 100 Barg at a temperature of from 400° C. to 900° C.

Abstract: The invention provides an apparatus which consists of two fluidized beds 1 and 2 separated by a vertical divides' 5. A positive displacement device such as an auger 3 moves the bed material from the reduction side to the combustion side of the device below the fluidization zone. The height of the two fluidized beds is equalized by movement of the bed material through a hole 4 In the vertical divider, from the high temperature side 1 (zone 1) to the tow temperature side 2 (zone 2). The bed material that moves through the hole 4 provides energy to drive reactions that may occur on the reduction side. Energy may also be provided to zone 2 by means of conductive and radiative heat transfer through the dividing wall 5. Energy is provided to zone 1 by means of an exothermic reaction, typically combustion of a fuel 13 using air 12.
