- Scope
- This standard specifies the technical requirements, test methods, inspection rules, packaging, marking, storage and transportation of 13X molecular sieve. This standard is applicable to 13X molecular sieves for general gas drying, purification of raw gas in air separation units (removal of H2O and CO2), and desulfurization of liquid hydrocarbon static natural gas (removal of H2S and mercaptans). Typical chemical composition: Na|(2)O·Al|(2)O|(3)·(2.8±0.2)SO|(2)·(6～7)H|(2)O Silicon to aluminum ratio: SiO| (2)/Al|(2)O|(3)=2.6～3.0 Effective aperture: 9～10A
