Catalyst selectivity in thiophene hydrodesulfurization: Effect of H2S and aging
The distribution of hydrodesulfurization (HDS) products of thiophene was compared on 9 different catalysts at different degrees of sulfidation and at aging in H-2/thiophene mixtures. The main products of HDS were C-4 and C-1-C-3 hydrocarbons. The effect of sulfur uptake on the products' distribution was similar for Co and Ni promoted, and reverse to that on Pd and Pt promoted samples. The effect of aging was similar for all samples.
