Deactivation by sulfur poisoning of tar reforming catalysts is a challenge for biomass gas-to-liquids processes.  In order to improve the understanding of deactivation and regeneration mechanisms, sulfur K-edge XANES was used in conjunction with reaction studies to examine sulfur transformations between sulfides and sulfates during regeneration schemes on Ni/Mg/K/Al2O3.
