摘要

Fluidized bed reactor (10) for producing product gas from carbon-containing input materials via allothermal gasification comprises: a combustion chamber (100) with a first fluidized bed (104) for producing heat required for the allothermal gasification; a reformer reactor (200) for carrying out the allothermal gasification with a second fluidized bed (208); and a feeding device for the input materials to be gasified. The reformer reactor is at least partially immersed in the combustion chamber, and defines a flow channel passing through the first fluidized bed. Fluidized bed reactor (10) for producing product gas from carbon-containing input materials via allothermal gasification comprises: a combustion chamber (100) with a first fluidized bed (104) for producing heat required for the allothermal gasification; a reformer reactor (200) for carrying out the allothermal gasification with a second fluidized bed (208); and a feeding device for the input materials to be gasified, where the reformer reactor is at least partially immersed in the combustion chamber, and defines a flow channel passing through the first fluidized bed, and the second fluidized bed is circulated in the flow channel in a predetermined flow direction. An independent claim is also included for producing product gas from carbon-containing input materials via allothermal gasification using the fluidized bed reactor, comprising: (a) producing the pyrolysis gas through pyrolytic conversion of the carbon-containing input materials in the pyrolysis section of the flow path; (b) producing a circulating flow of the second fluidized bed along the flow path, where the circulating flow comprises the pyrolysis gas and the solids formed during the pyrolytic conversion; (c) producing the product gas in the reforming section by absorbing heat from the first fluidized bed; (d) separating the product gas and the solids in the cyclone; and (e) recycling the solids in the pyrolysis section, and discharging the product gas from the fluidized bed reactor.
