Abstract

Ceramic open cell foam is proposed as an alternative structure in the automotive exhaust abatement system in the current work. Combination of zeolite and its interconnecting channels promote radial mixing and enhance turbulence which is highly desired in exhaust gas treatment. However, the associated pressure loss in the structure becomes a major limitation which may affect the overall engine performance. This paper addresses the pressure drop characteristic of alumina-zeolite porous ceramic (AZPC) filter and its effects towards engine performance. The filter employs polymeric sponge method to produce porous structure with a composition of 70 vol. % alumina and 30 vol. % of zeolite. Three filters were produced, namely the porous monolith, channelled porous monolith and cylindrical beads with the corresponding capacity for 1300 cc engine. Testing was conducted using a centrifugal blower having a flow rate up to 1224 m3/hour. Pressure difference for the filters were measured and compared to that of commercially available honeycomb monolith catalytic converter. The filters were then tested in the actual 1300 cc engine to determine the engine performance. Results show that the filters’ backpressure is within the 400 and 500 cells per square inch (cpsi) of honeycomb monolith and only deviates slightly from the existing catalytic converter. The AZPC filters depict high potential capability as the pollutant abatement in the automotive application.
