Problem to be solved: to provide a method of adjusting or regulating a filling level or filling height of a floor material held in a suspended state (floating state) of a carbonaceous material gasification apparatus, particularly a floating bed reactor.In a gasification apparatus for a carbonaceous material 300 for converting biomass and / or coke K into a gas 403, a downwardly tapered floating bed reactor comprising a lower inlet opening 301 is prepared and the raw material is directed downward. Gas gasification agent V is introduced upward.The flow rate of the gasification agent is adapted to the shape of the flow cross section of the conical reactor in consideration of the material characteristics of the biomass and / or coke so that a stable fixed bed held in suspension in the floating bed reactor is generated.The height of the upper boundary layer of the fixed bed in the reaction apparatus is adjusted by extruding in the reaction chamber and extracting the gas from the extraction pipe 303 provided in the reaction apparatus ceiling portion 302 with the particles, and the position of the extraction pipe determines the vertical position of the upper boundary layer of the floating floor.Diagram
