Molecular Sieve NSP-4
The molecular sieve NSP-4, also called zeolite NSP-4 or zeolith NSP-4, is a velocity separation type adsorbent. It mainly utilizes its characteristic of faster adsorption of nitrogen than methane. The kinetic selectivity of nitrogen to methane is 405. Compared with the traditional velocity separation type carbon molecular sieve, NSP-4 adsorbent has the advantages of larger nitrogen adsorption capacity faster than nitrogen adsorption rate. It is more suitable for methane enrichment.
