Small-pored crystalline titanium molecular sieve zeolites and their use in gas separation processes |
摘要 |
Novel gas separation agents with precisely and predictably controlled pore sizes within the range of 3-4 Angstrom units and their preparation from ETS-4 by exchange with cations, particularly multivalent cations such as strontium followed by drying and calcination to effect controlled pore shrinkage is disclosed. These novel materials have utility in gas separation processes particularly the separation of nitrogen from a mixture of the same with methane. |
