Zsm-5 Molecular Sieve

These ZSM-5 Molecular Sieve is produced from water glass and aluminum sulfate synthesis. Compared with organic synthesis
The ZSM-5 Molecular Sieve, characteristic of the simpler synthesis process, stabler quality, free of pollution, less cost, better hydrothermally, compared to those of ZSM-5 zeolite synthesized suing organic compounds

3a Structure State
Crystallinity a Y95%
Pore size 5A
Framework Density 1.81 (determined in isooctane)
Thermal stability The differential thermal analyst(DTA) curve shows that the crystal exhibits no major structural change up to temperature of about 1200a .
Hydro-thermal stability The binder-additive catalyst could retain its crystallinity when treated under 100% steam at a temperature of 700a for 12h.
