Selective Catalytic Reduction

An advantage of the SCR technology is its relative insensitivity to sulfur poisoning. Among the various types of catalysts, vanadium formulations show the highest resistance to sulfur. V/Ti based catalysts, practically insensitive to sulfation, have been traditionally used in industrial coal-fired applications of high sulfur content [2454].
