Abstract
A process is provided for the catalytic removal of sulfur compounds, such as hydrogen sulfide and sulfur dioxide, out of a gas by contacting the gas with catalyst composition containing a silicon carbide support and a catalyst component, such as a salt or elemental state of a metal, such as titanium, zirconium, yttrium, lanthanum, uranium, lead, molybdenum, iron, cobalt, copper, nickel, zinc and cadmium and an oxide of a metal, such as uranium, lead, calcium, magnesium and cadmium. The process may be conducted at a temperature above or below the dew point of sulfur.
