EnviCat GP catalysts address the high quality demands of technical gases, reducing the level of impurities to minimal levels.
The catalyst effectively purifies carbon dioxide (CO2), which is used in the production of urea (CH4N2O):
After the steam reforming process, which produces hydrogen from a hydrocarbon stream, the CO2 is separated. This CO2 must be purified: impurities such as hydrogen (H2), hydrocarbons (HCs), and carbon monoxide (CO) need to be removed so it can be reused for the urea synthesis process.
EnviCat GP also purifies oxygen (O2) which has been produced via electrolysis:
In a process called electrolysis, water (H2O) is decomposed into hydrogen (H2) and oxygen (O2) by passing an electric current. High-purity oxygen is required for many chemical processes. Any remaining traces of hydrogen must therefore be eliminated. EnviCat GP removes these trace impurities to achieve the necessary purity.
EnviCat GP catalysts are used to purify CO2 of impurities to minimal (ppb) levels for use in food and beverage applications.
