Martirosyan, Chemical Engineering, University of Houston, 4800 Calhoun, Bldg. 1, S222, Houston, TX 77054 and Dan Luss, Chemical Engineering, University of Houston, Houston, TX 77204 EPA regulation mandates a minimum of 90 % reduction of diesel engine emission of particulates to 0.01 g/mile. The reduction of the particulate material (PM) is accomplished by use of ceramic diesel particulate filter (DPF). The removal of the accumulated PM is still the most challenging aspect of this technology. Due to the relatively low temperatures of the diesel exhaust gas, the current state-of-the-art is to use catalytic assistance to reduce the soot ignition temperature and accelerate its oxidation. We use a simple computer model to study the diesel exhaust flow pattern, particulate upload rate, filter regeneration rate, and temperature distribution during the regeneration when different catalysts are used.
