Characteristics comparison of tar from lignite pyrolysis with inherent and simulated moisture for adopting a two-stage gasification process

•A new FBTS gasification process has been proposed for producing clean fuel gas.•Coal pyrolysis behavior was examined on a FB apparatus.•Effect of inherent and simulated moisture on tar property was compared fully. To utilize low rank coal cleanly and high efficiently, a new fluidized bed two-stage...
