PURPOSE:To efficiently treat exhaust gas, by introducing the exhaust gas from Diesel engine using fuel contg. <=0.05wt.% S content to a catalyst body carrying porous inorg. material and one or more kinds among Pt, Rh and Pd on a refractory three-dimensional structure. CONSTITUTION:The catalyst body is obtd. by carrying the porous inorg. material such as alumina, silica, zirconia on the refractory three-dimensional structure such as cordierite honeycomb monolith, ceramic foam and thereafter, by further carrying at least one kind of Pt, Rh and Pd. CO and HC are removed by introducing the exhaust gas of Diesel engine using internal combustion engine fuel contg. <=0.05wt.% S content to the catalyst body, and, generation of SO2 and SO3 mist can be reduced. |
