EXHAUST GAS PURIFICATION CATALYST AND PRODUCTION METHOD THEREFOR, AND METHOD FOR PURIFYING NITROGEN OXIDE IN EXHAUST GAS |
摘要 |
<p>An exhaust gas purification catalyst is made as a composition comprising titanium oxide (TiO 2 ), aluminum sulfate (Al 2 (SO 4 ) 3 ), an oxide of vanadium (V), and an oxide of molybdenum (Mo) and/or tungsten (W), wherein on titanium oxide having sulfate ions and aluminum ions adsorbed thereon obtained by making contact with aluminum sulfate at more than 1 wt% and not more than 6 wt% relative to titanium oxide in the presence of water, an oxo acid salt of vanadium or a vanadyl salt and an oxo acid or an oxo acid salt of molybdenum and/or tungsten are supported in a proportion of more than 0 atom% and not more than 3 atom%, respectively. By this, the degradation of catalyst performance can be suppressed even with exhaust gas containing potassium compounds at a high concentration in combustion ash.</p> |
