Abstract

The catalytic removal of pollutants including nitrogen oxides (NOx), hydrocarbons (HC's) and carbon monoxide (CO) in the exhaust of automobiles is generally performed by using monolithic supports coated with noble metal catalysts, notably platinum and rhodium (Pt/Rh) adsorbed onto a washcoat. This is typically achieved to within 90-98% conversion efficiency for average entry conditions (50<Re<400 at actual conditions), with pressure drops not exceeding 1.25-2 kN/m2. The monolith is a honeycomb structure, essentially composed of many parallel channels of square cross section. This therefore acts as a high surface area reactor. One of its drawbacks lies in the amount of precious metal requirements. With the increasing demand and price of thes...
