This work reports the first direct evidence of sulfur surface chemistry during catalyst regeneration on a Ni tar reforming catalysts used in real biomass-derived syngas with ~ 50 ppm H2S. These groundbreaking results demonstrate the importance of the regeneration protocols, which we are in the process of developing.
