The authors have developed a flow through Diesel Oxidation Catalyst that removes 60-80% of the soluble organic fraction (SOF) from diesel truck engine particulate emissions. This unique catalyst exhibits high reduction in total particulate matter (TPM) emissions and low sulfate formation using a novel proprietary washcoat formulation with low platinum levels. This paper describes performance results from engine emissions tests for TPM, SOF, and gas phase HC and CO reduction for fresh and aged catalysts under steady state an transient operating conditions. Using a novel laboratory technique, the authors simulate adsorption and subsequent catalytic combustion of the SOF. The technique allows for the analysis of all the liquid and gaseous products produced and the overall selectivity of the catalytic reactions.
