Abstract EN
SAPO 34 zeolite membranes were prepared on a tubular mullite support.
Before membrane preparation, the support surfaces were coated with seed crystals.
Seeds particles were prepared by hydrothermal synthesis.
Before seeding, the substrates were treated with polyvinylpyrrolidone (PVP) to orient the seeds.
Both the treated and untreated supports were seeded, and membranes were synthesized on those support tubes by ex situ hydrothermal method.
The PVP molecule exists in the two resonance structures.
Hence the acylamino bond –N+ = C–O-– acts as intermediate linker between support surface and seed surface.
Due to charge interaction, the seed crystals were anchored strongly to support surface.
The synthesized membranes along with seed crystals were characterized by XRD, FESEM, and EDAX analysis.
The single-gas permeation with CO2 and H2 was investigated.
Up to 5 bar of feed pressure, the permselectivity of CO2 and H2 was as high as 4.2.
