Theoretical and experimental demonstration of lignite chemical looping gasification of phosphogypsum oxygen carrier for syngas generation

•Phosphogypsum was used as oxygen carrier in CLG process for syngas.•Lignite was used as solid fuel in this paper.•Syngas generation is via solid–solid reaction and gas–solid reaction.•Optimizing operation condition has been obtained.•Contrasted experiment and theory analysis. Phosphogypsum (PG) is...
