The 5A molecular sieve is an alkali metal aluminosilicate with an effective pore opening of 5 angstroms(0.5 nm) and is the calcium-exchanged form of the type A zeolite. The strong ionic forces of the divalent calcium cation make 5A an excellent choice for removing carbon dioxide, alcohols and other oxygenates, methyl and ethyl mercaptans, and normal- and iso-paraffins separation, removing water, carbon dioxide, hydrogen sulfide from sour natural gas, while decreasing COS formation.. This product is also effective for the bulk separation of normal and iso-paraffin hydrocarbons. This type of molecular sieve has a high rate of adsorption and desorption, a higher rate of contamination resistance and a high crush strength.
The main application is the recovery and purifcation of hydrogen from raw gases. The hydrogen product meets every purity requirement up to 99.9 mol% and is achieved at highest recovery rates.
