Abstract
PURPOSE:To perform desulfurization and denitrification simultaneously with single method and device, by causing the carrier, where titanium oxide stabilized thermally by tungsten oxide is caked by the alumina matter, to carry iron oxide as the catalyst for simultaneous desulfurization and denitrification. CONSTITUTION:As the catalyst to remove simultaneously sulfur oxides and nitrogen oxides in exhaust gas from the combustion device of fuel containing sulfur such as a boiler, the carrier where titanium oxide stabilized thermally by tungsten oxide is caked by the alumina matter is caused to carry iron oxide. Then, this catalyst removes sulfur oxides and nitrogen oxides in exhaust gas simultaneously by the single device and the single operation method.
