Shuruaati Din
1960s me jab vehicles ki sankhya badhne lagi, tab air pollution bhi ek major concern ban gaya. Vehicles se nikalne wali harmful gases jaise carbon monoxide (CO), nitrogen oxides (NOx), aur hydrocarbons (HC) environment ko kaafi nuksan pahucha rahi thi. In gases ko control karne ke liye scientists aur engineers ne catalytic converter ka concept develop kiya.
1970s: Catalytic Converter ka Udbhav
1970s me catalytic converter ko officially introduce kiya gaya jab United States ne Clean Air Act pass kiya. Is Act ke tahat automobile manufacturers ko vehicles me catalytic converters install karna mandatory kar diya gaya. Is invention ka shrey Dr. Eugene Houdry ko diya jata hai, jo ek French mechanical engineer the. Unhone 1950s me catalytic converter ka initial concept develop kiya tha.

- Platinum (Pt)
- Palladium (Pd)
- Rhodium (Rh)
Yeh catalysts mil kar teen main reactions ko perform karte hain:
- Oxidation of Carbon Monoxide (CO) to Carbon Dioxide (CO2):
- CO + O2 → CO2
- Oxidation of Unburned Hydrocarbons (HC) to Carbon Dioxide (CO2) aur Water (H2O):
- CxHy + O2 → CO2 + H2O
- Reduction of Nitrogen Oxides (NOx) to Nitrogen (N2) aur Oxygen (O2):
- NOx → N2 + O2
Catalytic Converter ke Components
Catalytic converter kai components se mil kar bana hota hai. Yeh components mil kar exhaust gases ko treat karte hain:
- Core: Core catalytic converter ka main part hota hai. Yeh honeycomb structure me hota hai aur isme catalysts coat hote hain. Honeycomb structure hone se surface area badh jata hai aur gases ka catalytic surface se contact improve hota hai.
- Washcoat: Washcoat ek layer hoti hai jo core par applied hoti hai. Yeh catalysts ko hold karne me madad karti hai aur surface area ko aur bhi badha deti hai.
- Catalyst: Catalyst woh substances hote hain jo chemical reactions ko speed up karte hain. Platinum, palladium, aur rhodium catalytic converters me commonly use hone wale catalysts hain.
