Category-Wise Analysis

Three-Way Oxidation-Reduction Catalytic Converter - By Product

The three-way oxidation-reduction catalytic converter (TWORCC) is an advanced emissions control device used in gasoline-powered vehicles. It has three important functions oxidizing carbon monoxide (CO) into carbon dioxide (CO₂), converting unburned hydrocarbons (HC) into CO₂ and water (H₂O) and reducing nitrogen oxides (NO2) into nitrogen (N₂) and oxygen (O₂). A catalytic reaction of precious metals such as palladium, platinum, and rhodium does this process. The three-way catalyst shows high effectiveness when the air fuel ratio is regulated as it is a main component in vehicles to follow the stringent emissions standards. It is extensively used in passenger cars and light-duty trucks.

Two-Way Oxidation Catalytic Converter - By Product

The two-way oxidation catalytic converter (TWOCC) is predominantly utilized in older gasoline engines and certain diesel applications. Its primary function is the oxidation of carbon monoxide (CO) into carbon dioxide (CO₂) and the transformation of unburned hydrocarbons (HC) into CO₂ and water (H₂O). Three-way converters do not facilitate the reduction of nitrogen oxides (NO2), leading to less efficient meeting of strict emission standards. The two-way converters are more located in diesel engines as independent NO2 reduction systems such as selective catalytic reduction (SCR) are implemented. In response to removing environmental regulations, the two-way converters have a phase-out process in favor of more effective three-way catalytic converters.

Palladium - By Material

Palladium (Pd) is an important metal used in automotive catalytic converters specifically in applications involving gasoline engines. It functions as a promoter to carry on oxidation and reduction reactions that transform harmful emissions such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NO2) into less harmful gases. It is used for its superior catalytic properties, durability, and resistance to elevated temperatures. Over the years, its demand has increased as automakers have substituted platinum with palladium owing to cost benefits. The price of palladium has prompted research into alternative materials and hybrid catalyst formulations.
