ABSTRACT:
NOx removal catalyst can be obtained by kneading various kinds of inorganic fibers and water containing a surfactant to make a pulp-like substance, adding a catalytic 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 conventional various molding methods, and then dried and calcined for use. Instead of the above catalytic components; catalytic carriers such as titanium, zeolite, zirconia and the like may be shaped and calcined in the same manner and used for carrying a catalytic component. A particularly high performance and strength can be obtained with good result when a composition produced by calcining a molybdenum (Mo), vanadium (V) or tungsten (W) compound born on titanium oxide at 400.degree. to 700.degree. C. is used.
