Production of Metallic Catalyst Converter

In present research in order to reduce emitted pollutant gases from vehicles, design and production of metallic catalyst converter have been studied. The specimens are adjustable on different engines with different capacity. For this purpose the following steps were carried out: The first step is preparation of α- 4 sheet consists of annealing, forming and making monolith. The second step contains providing wash coat and catalyst metals and coating them on washed coated monolith. The last step is canning of catalyst converter. After accomplishing above steps, required tests have been done as below: Measurement of emitted pollutants from vehicles, stability of catalyst converter in vehicle (road test) and finally measurement of amount of fuel consumption of vehicles with different used catalyst converters in them. Results of these tests showed that emission of CO was equivalent with Euro3 standard and NOX emission was equivalent to Euro4 standard and NOX + HC emission was equivalent with Euro3 standard.
