Purification of Pure and Ultrapure Gases

Gas Purifcation – Catalysts and adsorbents for technical gases

Technical gases are used in a broad range of applications – from carrier gases in analytical systems, to process gases in industrial units, to food-grade components in consumer products. These gases are tailored for their particular use so the degree of purity is a critical consideration. To obtain the quality needed, gases must be purified to eliminate substances such as hydrocarbons, hydrogen, oxygen, carbon monoxide or sulphur compounds, to name but a few typical impurities.

Süd-Chemie´s catalysts and adsorbents are able to reduce the level of these undesirable substances to minimal levels of a few ppm or even ppb. Building on decades of research and practical application Süd-Chemie has developed the preferred products to address the high quality demands of this application. This is reflected in mechanically stable and durable products that ensure efficient and reliable purification of technical gases.

Diversity for individual applications

The EnviCat® and ActiSorb® series of products serve a broad range of applications and are suitable for use in highly-diverse compositions and concentrations of gas, and under a wide range of operating conditions. Even at low inlet temperatures, these oxidation catalysts and adsorbents achieve high levels of purity and high conversion rates. Offering thermal stability up to 1,000° C, specialized products also offer an impressive performance, even at extremely high temperatures.

To ensure superior performance, the products are developed for each application, selecting the optimal active components and carrier materials for the catalytic purification of technical gases.
