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.

The invention relates to an aftertreatment arrangement (1.0) for the aftertreatment of at least gases downstream of a fluidized bed gasification process, in particular downstream of an HTW gasifier (1) of a pressure-loaded fluidized bed gasification process, having a particle separation unit (2; 11) which can be arranged downstream of the fluidized bed gasification process and upstream of a gas cooler (3) that can be used for the further aftertreatment of the gases, wherein the aftertreatment arrangement comprises an intermediate cooling unit (12) which can be arranged downstream of the fluidized bed gasification process and upstream of the particle separation unit (11), having a return (B1) for gasification steam (B) that can be coupled to the fluidized bed gasification process. Furthermore, the invention relates to a method for the aftertreatment of at least gases downstream of a fluidized bed gasification process as well as the use of an intermediate cooling unit.

A pyrolysis and gasification system produce a synthesis gas and bio-char from a biomass feedstock. The system includes a feed hopper that has a flow measurement device. The system also includes a reactor that is operable in a gasification mode or a pyrolysis mode. The reactor is configured to receive the biomass feedstock from the feed hopper. The reactor is operable to provide heat to the biomass feedstock from the feed hopper to produce the synthesis gas and bio-char. The system also includes a cyclone assembly. The produced synthesis gas including the bio-char is fed to the cyclone assembly. The cyclone assembly removes a portion of the bio-char from the synthesis gas.

A multi-stage product gas generation system converts a carbonaceous material, such as municipal solid waste, into a product gas which may subsequently be converted into a liquid fuel or other material. One or more reactors containing bed material may be used to conduct reactions to effect the conversions. Unreacted inert feedstock contaminants present in the carbonaceous material may be separated from bed material using a portion of the product gas. A heat transfer medium collecting heat from a reaction in one stage may be applied as a reactant input in another, earlier stage.
