Hydrothermally Stable and Cost-Effective Sulfur Trap Materials For Catalyst Protection In Continuous Catalytic Hydrothermal Gasification
Short Introductive summary
Catalyst deactivation by sulfur compounds limits continuous cHTG of sulfur-rich feedstocks. To address this, hydrothermally stable, regenerable CeO2-based sulfur traps were developed and tested under supercritical water conditions. Doped and granulated CeO2 materials showed high sulfur absorption capacity, good regenerability, and mechanical robustness, demonstrating strong potential for long-term catalyst protection in cHTG processes.
