Abstract
PURPOSE: To obtain long life and superior heat resistance by supporting a platinum catalyst on a hardened body which contains limited rutile type titanium dioxide, magnesium silicate, silica, and lime aluminate at a prescribed ratio.
CONSTITUTION: A carrier of a hardened body consists of 10W30wt% rutile type titanium oxide with 0.25W0.4μm grain size, 10W30wt% magnesium silicate which has 50W100μm grain size and contains ≥45wt% silica and ≤30wt% magnesia, 10W30wt% spherical porous silica, and 30W50wt% lime aluminate which contains ≤42wt% lime and ≥50wt% alumina. On this carrier, a platinum metallic catalyst is supported. The catalyst produced as mentioned above has long life and superior heat resistance.
