A nitrogen-doped carbon-coated silicon carbide as a robust and highly efficient metal-free catalyst for sour gas desulfurization in the presence of aromatics as contaminants

As far as environmental chemistry is concerned, N-doped nanocarbons have been employed as efficient, selective and robust metal-free systems for the selective oxidation of H 2 S to elemental sulfur in tail gas treatment units. Modified Claus units that include tail gas treatments can reach up to 99....
