Ammonium-stabilized Levasil Colloidal Silica is the pure alternative for the effective selective catalytic reduction (SCR) vital to meet ever stricter regulations for both automotive manufacturers and power plants.

Reducing emissions – from both power plants and diesel engines for cars – is a growing global concern. With their low sodium levels, our ammonium-stabilized Levasil CA products are perfect for use in – and for improving performance of SCR catalysts, with benefits such as extended lifetime, increased productivity and optimized use of rare raw materials.

SCR is used to reduce emissions, particularly nitrous oxides. The best-known application is the catalytic converter that is an integral part of most vehicles powered by hydrocarbon fuels but also essential in stationary power plants.
