ZSM-5 Zeolite
ZSM-5 Zeolite
Synthesis of ZSM-5 by direct method
ZSM-5 zeolite is synthesized directly by reacting soluble glass with aluminium sulphate to ZSM-5 zeolite, not using organic amine. This product has been used as the parent of alkylationm, isomeration, aromatization and dewaxing catalysts and so on. The ZSM-5 zeolite, characteristic of the simpler synthesis process, stabler quality, free of pollution, less cost, better hydrothermally.
1,Chemical Composition
Production Introduction
| (SiO2/AL2O3)=38 | (SiO2/AL2O3)=50 | (SiO2/AL2O3)=25 |
AL2O3 | 3.8-3.9% | 2.3-2.5% | 5-5.5% |
SiO2 | 85-86% | 86.0-87.0% | 80-85% |
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% |
(SiO2/AL2O3)=25 | 9.5-10.5% | 2.05-2.5% | 11.0-12.0% |
3,Structure State
Crystallinity ≥95%
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 1200℃.
Hydro-thermal stability The binder-additive Catalyst could retain its crystallinity when treated under 100% steam at a temperature of 700℃ for 12h.
