Patent ID: 8128716

Claim:
A device for the pyrolysis and gasification of substance mixtures containing organic constituents, comprising a pyrolysis reactor ( 1 ) having an inlet ( 4 ) through which the organic substances or the substance mixture containing the organic constituents are introduced, a conduit ( 5 ) through which a heat transfer medium is introduced, and an outlet ( 7 ) for conveying, pyrolysis coke to a crack reactor ( 3 ); a fluidised bed combustion reactor ( 2 ) separate from the pyrolysis reactor ( 1 ) for the combustion of the pyrolysis coke and for the generation of the heat transfer medium for the pyrolysis reactor ( 1 ), wherein ash material from said fluidised bed forms said heat transfer medium and said fluidised bed combustion reactor ( 2 ) includes an ash conduit ( 5 ) extending from the an upper portion of the fluidised bed combustion reactor ( 2 ) to the pyrolysis reactor ( 1 ) and a waste gas conduit ( 12 ) extending from the upper portion of the fluidised bed combustion reactor ( 2 ) through which waste gas is discharged; and a non-fluidised crack reactor ( 3 ) separate from said pyrolysis reactor ( 1 ) and said fluidised bed combustion reactor ( 2 ), said crack reactor ( 3 ) having an inlet ( 8 ) for receiving water vapor and an outlet ( 9 ) for discharging synthesis gas, said crack reactor ( 3 ) being connected to said pyrolysis reactor ( 1 ) at one end and said fluidised bed combustion reactor ( 2 ) at an opposite end so as to receive raw gas from the pyrolysis reactor ( 1 ) through a conduit ( 6 ) extending from an upper portion of the pyrolysis reactor ( 1 ) to the crack reactor ( 3 ) for the purification of the raw gas generated by the pyrolysis , said crack reactor is integrated into the flow of solids from the pyrolysis reactor ( 1 ) into the fluidised bed combustion reactor ( 2 ) and comprising means for cracking and purifying the raw gas ( 6 ) using solids from the pyrolysis and/or combustion reactors ( 1 , 2 ) as catalyst.
