Research highlights

  1. Chemical looping gasification of biomass with Fe2O3/CaO as the oxygen carrier for hydrogen-enriched syngas production

  • Fe2O3/CaO was used as the oxygen carrier for chemical looping gasification of biomass.
  • Hydrogen production was promoted by one step reduction and oxidation of Ca2Fe2O5.
  • A temperature of no less than 800 °C was needed for a completed redox of Ca2Fe2O5.
  • Biomass ash destroyed the Ca2Fe2O5 structure to generate CaSiO3 and Fe2O3 during cyclic test.

 

  1. Steam co-gasification of horticultural waste and sewage sludge: Product distribution, synergistic analysis and optimization

  • Co-gasification of HW and SS was investigated using steam as gasification agent.
  • H2 content was increased and syngas yield was decreased with higher SS ratio.
  • Syngas yield and H2 production were significantly promoted by synergistic effect.
  • Optimal design and energy flow were performed for steam co-gasification.
