<p>PROBLEM TO BE SOLVED: To provide a technology to process dioxins by utilizing a mineral powder composition. SOLUTION: The mineral powder composition contains 60 to 75 wt.% of SiO2, 8 to 20 wt.% Al2O3, 1 to 5 wt.% of Fe2O3, 0.1 to 1 wt.% of TiO2, 2 to 4 wt.% of CaO, 1 to 3 wt.% of MgO, 3 to 5 wt.% of Na2O, 2 to 3 wt.% of K2O, and 0.01 to 1 wt.% of MnO as the major components. In addition, the composition contains potassium, selenium, germanium, zinc, copper, cobalt, nickel, molybdenum, lithium, vanadium, tungsten, barium and rubidium. The mineral powder composition has an emissivity of 80% or higher in an infrared wavelength region of 4 to 24μm. By spraying the solution of such a mineral powder composition to dioxins or the intermediates, dioxins are processed by this dioxin processing method.</p> |
