| Popis: |
Reduction of emissions from diesel engines using novel flow-through oxidation catalysts containing base metal oxides has been demonstrated. The soluble organic fraction (SOF) of the particulates can be converted and gas phase hydrocarbons can be removed via the proper choice of oxides. Low levels of platinum on the catalysts also compliment HC and CO conversion without leading to “sulfate-make”. Catalyst performance is shown for transient and steady state engine testing relative to emissions standards for U.S. truck and European auto applications. Laboratory studies using PYRAN TM thermal chromatography and engine storage & release test results provide insight of the mechanisms of removal and conversion of SOF and HC's by the catalysts. |
