  The following is the detailed introduction of our ZSM-5 molecular sieve :
  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 molecular sieve synthesized suing organic compounds
  
  1、Chemical Composition
  molecular formula ：AlKO4S
  (SiO2/AL2O3)=38 (SiO2/AL2O3)=50
  AL2O3 3.8-3.9％ 2.3-2.5％
  SiO2 85-86％ 86.0-87.0％
  
  
  
  
  2、Adsorption
  Adsorbent N-hexane Cyclohexane Water
  (SiO2/AL2O3)=38 9.5-10.5％ 1.9-2.3％ 9.0-10.0％
  (SiO2/AL2O3)=50 9.0-10.0％ 1.5-2.0％ 7.0-8.0％
  
  3、Structure State
  Crystallinity ≥95%
  Pore size 5Å
  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 1200℃.
  Hydro-thermal stability The binder-additive catalyst could retain its crystallinity when treated under 100% steam at a temperature of 700℃ for 12h.
