<p>NOx removal catalyst can be obtained by kneading various kinds of inorganic fibers and water containing a surfactant or its similars to make a pulp-like substance, adding a catalystic component thereto and then further kneading the resultant mixture to prepare a catalyst paste. The thus obtained catalyst paste is shaped into a honeycomb-like, plate-like or column-like form according to conventional various molding methods, and then dried and calcinated for use. Instead of the above catalystic components, catalystic carriers such as titanium, zeolite, zirconia and the like may be shaped and calcinated in the same manner and used, carrying a catalystic component. A practically high performance and strength can be obtained to bear a good result when a composition produced by calcinating molybdenum (Mo), vanadium (V) or tungsten (W) compound born on titanium oxide at 400 to 700 DEG C is used.</p> |
