Preparation and gas permeabilities of zeolite membranes
- Dalian Univ. of Technology (China); and others
Zeolites with less than 10 {angstrom} pore are desirable membrane materials, due to their crystallinity, resistance to high temperature, and chemical inertness. A variety of new membranous materials were synthesized composed of a continuous intergrowth of 5-50 micrometer type A, X, Y, or ZSM-5 crystals. The membranes were crystallized under hydrothermal conditions at 90 to 220{degrees}C on the external surface of a porous ceramics. The reagents used were aluminum sulphate, water glass (20.1 wt% SiO{sub 2}, 6.09 wt% Na{sub 2}O, 73.8 wt% water), sodium hydroxide, sulphuric acid, deionized water and templating agents. The molar composition was: 0.1-0.5 Na{sub 2}O:1 SiO{sub 2}:0.04-0.05 Al{sub 2}O{sub 3}:20-60H{sub 2}O.
