Opal Pure™ zeolites offer cutting-edge emission control solutions for automotive and chemical industries. With our extensive experience, Ecovyst, through its Zeolyst International joint venture, proudly presents Opal Pure™ zeolite products designed for emission control applications, delivering exceptional performance in the following areas:

1. NOx Abatement: Whether for automotive or stationary sources, Opal Pure™ zeolites are a popular choice for SCR catalyst applications, surpassing traditional Vanadium-based methods. Opal Pure™ zeolites deliver remarkable catalytic activity at low exhaust temperatures, remaining efficient and stable even at high temperatures. Notably, Opal Pure™ zeolites do not contribute to the emission of vanadium into the environment, avoiding potential environmental impacts associated with heavy metals.
2. VOC Adsorption: Thanks to the hydrophobic properties of specific zeolites, Opal Pure™ zeolites excel at selectively adsorbing VOCs—effectively separating these pollutants from exhaust streams. Opal Pure™ zeolites efficiently adsorb VOCs and desorbs them when exhaust gas reaches a sufficient temperature. 
3. VOC Abatement: When used in catalyst wash coat preparation, Opal Pure™ zeolites provide higher tolerance to poisons and lower ignition temperatures compared to alumina-based solutions. Opal Pure™ zeolites also exhibit a lower tendency to form harmful byproducts, thus reducing the formation of pollutants.
4. N2O Removal: Metal-exchanged zeolite catalyst solutions for chemical and automotive industries. Opal Pure™ zeolites can be tailored to selectively reduce nitrogen oxides (NOx) while minimizing the generation of unwanted byproducts, effectively reducing N2O emissions.

Applications:

• Automotive SCR (Euro 6)
